defective lcd panel vizio horizontal and vertical lines in stock

Lines can appear as a result of signal problems or interference, bad connections or resolution incompatibility with other devices. Most problems with lines on a Vizio LCD TV can be resolved if you troubleshoot the device.

Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

Check for loose connections with the cord. Inspect if the display problem is consistent with all channels and inputs from other devices. If not, it may be a signal issue. Try toggling between picture modes from the ‘Picture’ menu.

On average, your TV screen repair with vertical lines costs between $150 and $400. The TV’s motherboard or control board are usually the problem, and it could sustain damage that requires you to replace or repair it.

If your flat screen TV has the dreaded vertical lines, half of the screen has turned darker, the screen is cracked, or the screen is broken, this can be repaired but may cost more than you paid for the complete TV. If your screen is cracked or broken, you can try replacing the Screen, LCD, Plasma, or LED part.

But despite being advanced systems, Vizio TVs sometimes fail to work, and you get many errors when using them. Many Vizio TV user complaints revolve around the device screen flickering constantly, SmartCast failing to load, and the TV turning on but not showing pictures.

A bad cable, or a cable that is not securely fastened to the input/output ports, can disrupt the signal and cause horizontal or vertical lines. Verify that the cable in use is secured correctly at both the external device and the TV.

If you want to reduce waste or have a simple fix, repairing your TV is worth it. However, sometimes the cost of repairs can exceed the cost of a new TV. Therefore, depending on the age of your TV and the parts you need to replace, replacing your old TV with a new model is more cost-effective.

The national cost average is $100 to $300 for TV repairs, with most people spending about $200 to repair an inverter in an LED TV.TV Repair Cost by Brand.BrandRepair Costs (Labor Included)

A Vizio TV can last you about 7 years on average, but you can extend their life up to a possible 10 years with a little sensible care. Vizio are great TVs that you can enjoy for a long time and today we’ll tell you all about how you can do that.

Vizio is offering a warranty part replacement on all the units with the bad chip assembly. Vizio will replace a recalled TV that has already lost its picture with a new unit (not a refurbished one as they customarily do) according to its customer service representative.

If for whatever reason you do not have access to your TV’s remote, you can still factory reset your Vizio TV. To do this find the power button on your TV. Depending on the model you have this may be on the right hand side, left hand side, or very bottom of the device.

If your Vizio TV keeps restarting during setup, it may be that the voltage current coming from the outlet might be fluctuating too much. To confirm, plug a voltmeter into the outlet and if the current value is too low or fluctuating, you may need to find another outlet or replace the current one.

Why Should you Trust Me?Hi, I am Anirban Saha, an Engineer with a Specialization in Electronics and Communication Engineering. I have experience with electronics circuits and computer peripherals.

Vizio Smart TVs are known for their value for money. However, some users have been reporting that they are experiencing horizontal lines on the screen.

Another common cause is a problem with the TV panel. If there is a problem with the hardware, it can also cause horizontal lines to appear on the screen.

If you have a new TV, the screen maybe is just dirty or dusty. Still, you need the help of a technician as you won’t be able to peek into the panel yourself and it is also not recommended to do it on your own.

Lines that can appear on your TV can be horizontal lines running horizontally across your TV’s width or they can be colored vertical lines running vertically on your Vizio TV display screen.

When a horizontal line appears on the screen of your Vizio TV, it can be either a problem with your TV, or it can be a problem with your cable or satellite box.

If the horizontal lines are not caused by the cable or satellite box, then the problem is with your Vizio TV. A black horizontal line is not always a panel issue.

You can connect your Laptop by connecting the HDMI cable to it for a while and check the picture quality and whether it is showing the same horizontal lines on your Vizio Smart TV Screen.

If you are facing the issue of the horizontal lines on your Vizio TV screen and you want to fix this issue, then you need to update the firmware via their OTA updates to the latest version.

The first thing you want to do is to check if your Vizio TV has the latest software updates. If the TV is still new, you might want to check for updates more often.

If you haven’t yet, you can easily do this by using your remote control going to the Home screen and then to the Settings menu screen. You will find the option to check for updates in the Support area. If there are updates available, download them.

Either you need to compromise on your viewing experience by viewing the horizontal line on your screen or you need to replace your Display panel to eliminate any horizontal line.

If the panel is an LCD panel, it will be cheaper and it would cost more to replace if it is an LED panel. Also, costlier if you have an OLED panel or OLED panel.

This is a very common problem, and I hope that I was able to help you to fix horizontal lines. This is also seen in other TVs like Philips Tv, Sony TV, Samsung LED TV, LG TV, Panasonic TV, and almost every brand of TV.

See the white line on TV pictured above? If you see a line on your TV screen it might be the result of several causes. Some might be simple to fix and others may actually require you to replace the TV.

Pixels on a TVs display panel are organized in groups of straight vertical lines. If a single pixel fails this may cause the entire group of pixels to fail as well. This then creates vertical lines as pictured here.

Lines can fail in a big group creating a thick line that is always present. In the photo of the TV above a series of pixel lines failed together creating the white block on the display.

The point is you want to look at the picture form at least two devices connected to the TV. Check to see if the line is visible when using both devices. If the line is only visible when using one device then the problem is coming from whatever device is connected when you see the line. If the line is visible on multiple devices connected to the TV then the problem is likely a panel line defect.

TVs with line defects need to be replaced. The cost of repairing a TV like this would end up equaling the cost of a brand new television so attempting to repair it isn’t even worth it.

If your Vizio TV was purchased less than 12 months ago the warranty will still be active. Vizio’s warranty for new TVs covers any factory defect. A panel line defect is considered a factory defect.

Vizio will replace the TV. There are a couple different options for replacement depending on the size of the TV. Smaller TVs will be replaced through the mail. TVs that are 40″ or larger are eligible for an in home replacement.

If the warranty on your TV is expired then there isn’t much that can be done. You would be better off replacing the TV rather than attempting to repair it. The cost of repairing the panel would be close to the cost of going out and buying a brand new television.

I hope this information has been helpful. Do you have any other questions or comments about line defects or other display problems? If you do please leave them in the comments section below. And please remember to like the article on Facebook and share on Twitter.

In my experience, Vizio TV screen problems are not super common, but if something does go wrong, then this often shows as horizontal lines on Vizio TV screens.

You want to know,“Can the horizontal lines on my TV screen be fixed?”, and the simple answer is, “Yes”, whether they are thin black horizontal lines or even green lines or horizontal red lines on your Vizio TV.

Depending on the exact type and number of horizontal lines you are seeing determines the correct solution, so read through this article carefully, and hopefully we can fix your Vizio TV and avoid an expensive replacement.

Fix horizontal lines on your Vizio TV screen by unplugging your TV from the wall outlet, then re-seat all HDMI and other connection cables in the back of the TV, before plugging it back in again. If needed, remove the TV’s back panel and re-seat the T-Con ribbon, using compressed air to clean its contacts.

I’ll go into more detail on the possible fixes below for Vizio TV horizontal lines on screen, but remember before you do anything, that removing your TV’s back panel is likely to void your warranty.

So, if your TV was purchased within the last year, or has an extended warranty, you are much better to contact Vizio’s service center before performing any of the more invasive fixes.

Note that there are quite a few possible causes of horizontal lines, so it pays for you to first make a note of the exact types of horizontal line you are seeing so that you can match them to a solution.

If you have any compressed air, use that to clean the contacts both of the cable and in the connector on the TV. If you don’t have compressed air, then blow gently on them.

You can also try removing all external devices, including those connected by Bluetooth and any coaxial or signal cables, so that the TV only has a power cable going into it.

Pull up the on-screen menu to see if the lines are still there. If they are, this means that your external connections are fine and the problem is located within the TV.

If your TV is on, then you know that your wall socket is suppplying power, but the question is whether this is constant without fluctuations and is of a sufficient voltage.

If you don’t have a wall socket testing rig, then just unplug your TV, remove any surge protectors and try another appliance that you know draws a similar current. Check if this works as expected.

Most Vizio TVs support auto-updating of firmware, but you can’t assume that this is turned on for you, unless you are using a Smart Vizio TV, where auto-updates are always on.

If you are using a Smart Vizio TV, then there is no option to manually update firmware – this is done automatically as long as your TV has an Internet connection.

Removing the back panel from your Vizio TV will void its warranty, so if you have bought it in the last year, then you are best to contact Vizio support and get them to either fix or replace your TV.

Gate drivers are connected to the TV’s panel by a ribbon cable, and the contact can sometimes come loose. They are bonded within the factory so are not user-replaceable, but you might find that squeezing the sides of your TV next to the thin black line helps to resolve it.

If your TV shows a complete black line across the screen, then you can assume you have single row drivers. Try squeezing the panel on both sides unless you know which side the gate driver is on.

If this does resolve the issue, then opening the back panel using the instructions in the next step, and applying tape to keep pressure on the ribbon cable should fix it.

If the issue isn’t fixed, then either the gate driver itself is faulty and needs to be replaced, which most probably requires a new panel, or there is a possibility of an issue with the T-Con board.

It’s hidden away under the back panel, behind the screen, and is a regular source of horizontal lines in TV images because it connects to the LCD / OLED panel with ribbon connectors which can come loose.

To access the T-Con board, you need to remove the back panel. If you’re not confident doing this, then now is the time to get an expert in. Otherwise:

Unplug your TV, hold down the power button and wait for at least 30 minutes. There are large capacitors in the power board for the backlight and these can hold charge for an extended period of time.

The position of the boards will vary by model, but the T-Con board can be identified by the ribbon cables connecting it to the TV’s panel. Identify the main three boards you will see in the images below.

Then, you should be able to remove the cables by pushing the locking cover down and they will then easily come away from the board. Don’t try to force them out without unlocking them first.

After removing the ribbon cable, take a look at the individual connectors on the ends of the cables, and the connectors in the socket. You are looking for any signs of corrosion, damage or dust.

The contacts should be a shiny gold or silver color. If they are dull and appear to have a rough, copper-like layer over them, this would indicate oxidation and therefore a new cable is recommended.

If there are still horizontal lines, there’s a good chance that there is a fault somewhere on the T-Con board itself. These can be replaced for around $30 from eBay.

T-Con connection issues are generally implicated in vertical lines in TV screens, rather than horizontal lines, but this is worth a try if none of the other steps have worked for you.

If you are still struggling, then any further work is likely to be beyond most home users, so I would suggest contacting Vizio Support is the next best step.

But all of the solutions for why there are lines on your Vizio TV fall into the four groups below. You can eliminate some possible causes by thoroughly investigating these below.

Any slight knock to a cable can partially unseat it from its connector. This is especially true of HDMI cables and other cables that deliver a picture and are physically connected to your TV, and of course includes cables internal to your TV, like the T-Con ribbons.

We haven’t yet looked at this, but it should go without saying that if your TV has been subject to any physical damage, including falling over or even being dropped during installation, then this can both physically damage the boards inside the TV and dislodge any internal cabling.

Because there are several possible causes for horizontal lines on your TV, you can help to diagnose the issue you are having by identifying the type of horizontal line you are seeing.

If they are fixed and not moving, that suggests there is physical damage to your TV, either directly to the panel, or to an individual connector on the T-Con ribbon or gate drivers, or elsewhere in the cabling.

If your Vizio TV screen glitch is horizontal lines that move around the screen, this suggests a failure directly within the T-Con board itself, rather than a physical breakage somewhere within the system.

It’s also important to check that if you pull up your on-screen menu on the TV, do the lines pass through the menu or are they only on the video underneath?

The video below gives a good example of static horizontal lines (even though there is apparent movement at the top of the screen, this would still be classed as non-moving).

If you see a single black horizontal line across your TV, whether it is LCD or OLED, it is either a broken row electrode or a failed gate driver. For panels that use double-ended row drive, the black line may only extend halfway across your panel.

If you see a number of black horizontal lines together, then the ribbon cables connecting the gate drivers at the side of the panel have probably lost some of their bonding. Try a little pressure on the sides of the panel, and if this fixes it, then remove the back panel and apply tape to the ribbon cable connectors to replicate the pressure you were applying.

It could also be a faulty Tab connection to the LCD panel, which would mean an LCD panel replacement – something that is almost as expensive as the TV itself.

There is a clever solution to fix this: you have to open up your TV to get at the T-Con ribbon, remove this and then add pieces of non-conducting tape to each of the contacts in turn. Test the TV after adding a piece of tape, and eventually this should stop the ghosting.

If you haven’t been able to fix your problem using the steps above, then your next port of call should be to Vizio customer support, who can advise you if they are able to fix it.

Whether you have a single vertical line on your TV screen or your Vizio TV has colored vertical lines, there are a number of proven fixes that you can try to get your TV working again.

The most common causes of Vizio TV vertical lines are bad connections within the T-Con board, but there could be something either simpler or more serious going on.

Because the type of vertical lines that you are seeing on your TV can give an indication of their cause, I’ve also included a section to help you to identify the lines you are seeing, which might be helpful to read to ensure you try the correct fix.

First power cycle your TV, unplugging it from the wall for 30 minutes and holding down the TV’s power button for 15 seconds, before plugging it back in. Also try re-seating the HDMI and other cables. Finally, open the back panel, clean the T-Con ribbon with a non-static duster and 99% isopropyl alcohol, and replace the T-Con board if the issue persists.

So, if your TV was purchased within the last year, or has an extended warranty, you are much better to contact Vizio’s service center before performing any of the more invasive fixes.

If you have any compressed air, use that to clean the contacts both of the cable and in the connector on the TV. If you don’t have compressed air, then blow gently on them.

You can also try removing all external devices, including those connected by Bluetooth and any coaxial or signal cables, so that the TV only has a power cable going into it.

Pull up the on-screen menu to see if the lines are still there. If they are, this means that your external connections are fine and the problem is located within the TV.

If your TV is on, then you know that your wall socket is suppplying power, but the question is whether this is constant without fluctuations and is of a sufficient voltage.

If you don’t have a wall socket testing rig, then just unplug your TV, remove any surge protectors and try another appliance that you know draws a similar current. Check if this works as expected.

Most Vizio TVs support auto-updating of firmware, but you can’t assume that this is turned on for you, unless you are using a Smart Vizio TV, where auto-updates are always on.

If you are using a Smart Vizio TV, then there is no option to manually update firmware – this is done automatically as long as your TV has an Internet connection.

Note that for modern Vizio TVs that use a local dimming array for their backlight, you can see large vertical lines on your TV screen after updating the firmware.

This is caused by changes to the tolerances in the local array, and can be fixed by manually changing your backlight / gamma / brightness / contrast settings.

Removing the back panel from your Vizio TV will void its warranty, so if you have bought it in the last year, then you are best to contact Vizio support and get them to either fix or replace your TV.

Hopefully your Vizio’s vertical lines on screen have now gone following the fixes above, but if not, then you we will have to move onto some more invasive procedures.

It’s hidden away under the back panel, behind the screen, and is the most common cause of vertical lines in TV images because it connects to the LCD / OLED panel with ribbon connectors which can come loose or get covered in grime or dust, impeding their contact.

To access the T-Con board, you need to remove the back panel. If you’re not confident doing this, then now is the time to get an expert in. Otherwise:

Unplug your TV, hold down the power button and wait for at least 30 minutes. There are large capacitors in the power board for the backlight and these can hold charge for an extended period of time.

The position of the boards will vary by model, but the T-Con board can be identified by the ribbon cables connecting it to the TV’s panel. Identify the main three boards you will see in the images below.

Then, you should be able to remove the cables on the T-Con board by pushing the locking cover down and they will then easily come away from the board. Don’t try to force them out without unlocking them first.

After removing the ribbon cable, take a look at the individual connectors on the ends of the cables, and the connectors in the socket. You are looking for any signs of corrosion, damage or dust.

The contacts should be a shiny gold or silver color. If they are dull and appear to have a rough, copper-like layer over them, this would indicate oxidation and therefore a new cable is recommended.

If there are still horizontal lines, there’s a good chance that there is a fault somewhere on the T-Con board itself. These can be replaced for around $30 from eBay.

This works because the T-Con cable sends a clock signal through a handful of the pins (usually 8 pins per cable) which is implicated in the most common issues of vertical lines on screen.

And with two cables, one for each side of the TV, you can use the signal from the working side of the T-Con board to fill in for the faulty clock signals on the other side.

Note that this method will only work if the lines on your screen are either on the right or left hand sides, as blocking the pins on one cable causes the signal from the other cable to fill in for the blocked cable.

It can take some trial and error to get this right, so I recommend you check out the video below for a good demonstration of how to follow this approach.

The type of vertical line you are seeing can give a clue as to the possible solution. Use this guide if you want to target your fixes if your Vizio TV has vertical lines on screen, rather than following them all in order as above.

Single vertical lines on your TV screen can be caused by either loose tab connectors or gate driver failures, depending on the color of the line. The signal moves from the T-Con board through the ribbon cable to Tab Connectors and then to Gate Drivers, where the signal is displayed on screen as the image you see.

A single purple or red line on your Vizio TV screen is usually caused by a failure of a gate driver, which is an integral part of the TV’s panel and cannot be easily replaced at home without changing the entire panel.

A thin vertical line on your TV screen means that there is a loose tab connector, which carries the signal from the T-Con board through to the gate drivers and the panel. A black vertical line usually means that the tab connector has lifted slightly from its factory seating, and can be re-seated by squeezing the edge of the panel next to the black line.

If this clears the verticl black line, then open the back panel and apply some tape to the tab connector to maintain the pressure and remove the line.

Flickering lines on your TV screen are caused by a faulty clock signal on the T-Con board. You need to block this faulty signal using sticky tape on one of the T-Con ribbon cables, which allows the clock signal on the other side of the T-Con board, using the second ribbon cable, to compensate for the faulty clock signal and will remove the flickering lines.

Fix vertical blue lines on your Vizio TV screen by squeezing the plastic panel at the top or bottom of the line, as this will put pressure on the tap connector that has likely failed, re-instating the connection and removing the blue line.

If the blue line only disappears temporarily, then you will need to open the back panel and apply sticky tape to the tab connector to keep pressure on it so that it maintains a connection.

This only applies to TVs with a local dimming array, like HDR 1000 screens, and is caused by imperfections in the backlight grid itself or the logic that drives it.

Essentially, these bands would have been present before the update (so were not actually caused by it), but because the update affected the tolerances of the local dimming grid, the vertical bands have now become noticeable.

The only way to fix this (other than entirely replacing the backlight and circuit boards that drive it), is to carefully change each of your gamma, brightness, contrast, tone mapping or backlight settings until the banding becomes less prominent.

Any slight knock to a cable can partially unseat it from its connector. This is especially true of HDMI cables and other cables that deliver a picture and are physically connected to your TV, and of course includes cables internal to your TV, like the T-Con ribbons.

We haven’t yet looked at this, but it should go without saying that if your TV has been subject to any physical damage, including falling over or even being dropped during installation, then this can both physically damage the boards inside the TV and dislodge any internal cabling.

TV screen lines are an irritating occurrence, and many different issues with the TV can cause them. This article will go over what causes this, whether or not you can fix it depending on the cause, and how to fix it.

When any part of a TV"s display gets damaged, corrupted, or is defective, it can cause lines to appear on the screen. Some TV parts that can cause horizontal lines to appear are the LCD panel, T-Con board, or row drivers.

Issues with these parts can happen for many reasons, and the way your lines appear can tell you a lot about what"s wrong. If the lines are new, one of these parts was likely damaged.

If you"re seeing colored horizontal lines, it may be because of the T-Con board. If other parts don"t seem to be an issue, this part of the TV could be causing the lines.

If lines appear on your TV, you"ll want to inspect the TV itself. You can fix some issues that cause lines to appear, but others may require a professional or a new TV altogether. Some of the most common causes of horizontal lines are:

LCD screen damage. The LCD provides your TV display with light. If you"re handy, you might be able to fix this by doing a little work with the insides of the TV, which you can read about below.

Knock or tap on the back of your TV. If the issue is with cable connections, this could solve the problem. It could also indicate a problem with your T-Con board. It won"t fix the issue, and the lines may reappear, but it can give some insight into the problem. If it"s your T-Con board, you"ll want to have T-Con replaced.

Run a picture test on your TV. It"s a built-in feature on newer TV"s which allows you to see if the TV display is corrupted. Doing this may look different depending on your TV, but generally, you can go into the settings and find a support option or just a picture test option.

Take a look at the LCD screen. If it"s damaged, you may want to get the screen repaired or replaced. It may be a less costly option than buying a new TV altogether.

Vertical lines on a TV appear for the same reasons as horizontal lines: loose cables and wires, screen damage, or a faulty T-Con board. Leaving the TV turned on for too long can also cause vertical lines.

The steps for fixing lines on your TV will also work to fix TV glitches like flicker and stutter. For example, check the cables and connectors and ensure there"s no issue with your input device.

If your TV screen looks blue, it could be faulty connections, a defective backlight, or incorrect color settings. Some LED TVs naturally have a blue tint, which you can offset by changing the color temperature.

To fix screen burn on a TV, adjust the brightness settings and enable pixel-shift. Sometimes playing a colorful video with fast-moving action for half an hour might help.

"""Got a 24” smart tv D24f-F1 model. Got a blackscreen with blurry vertical lines. the only part of the screen that is still visible is the very top of the screen. If i leave it on for several hours sometimes it comes back to focus but i have been curently waiting an hour an 45 minutes for it to come back and still nothing. Any suggestions? I have tried a power cycle with no results and was told to factory reset but cant see the menu :(

A Vizio TV can last you about 7 years on average, but you can extend their life up to a possible 10 years with a little sensible care. Vizio are great TVs that you can enjoy for a long time and today we’ll tell you all about how you can do that.

Vizio is offering a warranty part replacement on all the units with the bad chip assembly. Vizio will replace a recalled TV that has already lost its picture with a new unit (not a refurbished one as they customarily do) according to its customer service representative.

If for whatever reason you do not have access to your TV’s remote, you can still factory reset your Vizio TV. To do this find the power button on your TV. Depending on the model you have this may be on the right hand side, left hand side, or very bottom of the device.

If your Vizio TV keeps restarting during setup, it may be that the voltage current coming from the outlet might be fluctuating too much. To confirm, plug a voltmeter into the outlet and if the current value is too low or fluctuating, you may need to find another outlet or replace the current one.

In this post we present another notorious issue that many encounter on their flat screen LED/LCD TV displays. Below are 2 videos showing how to fix TV displays that are manifesting the annoying horizontal and/or vertical lines problem.

The first video shows how to troubleshoot and fix an LG flat screen TV (model 42LN5400). Note that this may also be applicable to other brands (e.g., Sanyo, Panasonic, Samsung, Vizio, etc.). One key thing to determine here is whether the horizontal or vertical lines are flickering on and off and aren’t permanent. If the lines are permanent, then this may be indicative of a bad LCD panel which is a more complicated problem that can’t be fixed easily (or cheaply). The video does a great job showing examples to help differentiate the possible causes of the lines appearing on the screen.

The common culprit that first needs to be investigated is the possibility of a faulty T-Con board and the video shows possible symptoms of this problem, where to source it and how to replace it. The symptoms to watch out for include:Discolored screen

One key thing to note is that there are more than one different kinds of horizontal and vertical lines that can manifest on an LED/LCD TV screen. Case in point, if the lines are horizontal, permanent and solid black then it is highly likely a bad LCD panel itself. Vertical lines are more likely indicative of a bad T-Con board or possible connection issues with the T-Con board.

In the next video below a similar problem of vertical lines showing on the screen but with an added complication of the TV turning off and then on by itself. This seems to be a bit more complicated problem and the video provides the step-by-step instructions on how to troubleshoot and repair the problem. Note that the T-Con board is also included in the troubleshooting process here.

Key safety tip: Unplug your TV before performing any steps. Note that if the Standby light is on, then there is standby voltage going into the main logic board. Be safe.

Some Televisions also have an option to "Soft Power Cycle" in the menu. To access this press the menu button and choose System > Reset & Admin > Soft Power Cycle.

Step 3: Check to see if the issue happens on another device, or an app. You can also check the TV"s menu by pressing the "Menu" button on your VIZIO remote.

If your TV has a display issue, the TV will usually have the issue on all content. You"ll see the same problem when watching your cable box and your blu-ray player. You"ll also generally see the problem affect the menu. If the issue only happens when watching 1 device and can"t be seen when looking at menu, you may want to contact the manufacturer of your video device for assistance.

Press the menu button on your VIZIO remote, and choose System > Reset & Admin > Reset to Factory Settings. In some models it may be under the "Help"option instead of "System"

If your Vizio smart TV no longer works, you may need to replace its display. Before you choose a replacement screen, make sure you have the TVs model number and screen size in inches. You need to ensure the replacement unit you select is a match for your Vizio TV. Screens manufactured for one brand are usually not compatible for use with other brands.
