The easiest way to fix dead pixels  is to replace the whole screen with a new one. Technically you can replace pixels, but it would be more expensive and time-consuming than just getting a new display. The cost of the screen depends on the phone. Approximately you need to spend $50-150 for the spare parts. If you go to the service center, be prepared for a $50-100 repair fee.

These tubes can break and lose the liquid, so they can’t illuminate. That leads to dark spots that you can see even at night. And they are signs that you need to hurry up to fix the black spot on the LCD phone screen.  This liquid will continue to spill and contaminate nearby pixels, and this spot will get bigger with time. The approximate time of contamination of the whole display varies from 3-5 days to 2-3 weeks. It depends on the size of the amount of spilled crystal liquid. So change your display as soon as possible.

Teslong camera probes are typically available in three different lengths - 1, 3, or 5 meters long (3.2, 9.8 or 16 feet). Deciding which length to buy depends on your application - essentially how deep inside of something you need to look? The 1m length is good for most nearby applications like inspecting a rifle barrel, looking in an engine block or a computer case. The medium-length, 3m, probe is great for looking down exhaust pipes, investigating plumbing clogs or seeing what's inside your wallboard. For anything longer than that, reach for the 5-meter probe - there isn’t a big disadvantage to having a longer cable except you need to roll it up to store and it’s a little bunkier than the shorter options. Most people and applications will be served fine by the medium-length, 3m-long camera probe.

This issue doesn't spread out. It’s just a burnout bulb. If the black spot is getting bigger, it’s not a “dead pixel” case. That means you need to take more severe measures to prevent a display failure.

An industrial endoscope with a screen is very easy to use. First, make sure the device is fully charged. Next, install the camera probe into the monitor - it will either thread onto the monitor or it will plug into the monitor. Press the power button for a few seconds and the screen will illuminate. Use the Mode (M) button to switch between photo, video and viewing modes. All you have to do now is insert the camera probe into something you are inspecting and record photos and video by pressing the camera button.

Teslong endoscopes and borescopes use two types of connectors: USB-C or our thread-on aviation connectors. Our popular household models, the MS450 and NTS500b monitors, both use the USB-C connectors and they have interchangeable camera probes. These monitors can also be used with the aviation screw-on connector probes with the purchase of an NTG100-Q2C adaptor from our accessory page. Teslong NTS500, NTS450, and NTS300 professional/industrial monitors use the thread-on aviation connectors.

Teslong has been making inspection cameras including industrial endoscopes for over ten years so we have used over a decade of customer feedback to improve our designs and pack the best features into our products. We make stand-alone, USB, and WiFI devices to be compatible with any work situation and also a broad range of camera probes to perform inspections in many different environments.

It also may be an internal problem like the swollen battery. If your device runs out much faster than it used to, replace the battery.

Replacing the screen is the simplest but at the same time, the most expensive option to solve the problem. It won't be good for you if the screen costs a little less than your phone. So try to fix the black spot with useful video tools or a simple phone reboot.

Telsong’s camera probes typically are available with either a single-lens design, plus a right-angle mirror, or they are available with a dual-lens design. The single-lens-with-mirror probes are less expensive, and they are better for looking sideways at surfaces up close. Most commonly, this benefits Teslong’s gun borescope customers. The single-lens-plus-mirror design can slip down a gun barrel and look sideways at the fluting of the barrel right next to the lens probe. If you use a dual-lens probe for this type of application the right-angle lens will actually be too close to the gun barrel surface and sharp focus will be impossible. This is why all of our gun borescopes use a single lens with a mirror instead of a dual lens. For most other applications, like looking down a spark plug hole into the combustion chamber of a car engine, the dual lens design typically works better and gives a wider field of view.

Here is an example: your display needs to turn some pixels white. To do this properly, it should turn on all three bulbs. But for some software reason, it turns on only two bulbs: red and blue. And this pixel turns out violet, but not white as it is supposed to be.

An all-in-one endoscope or borescope is one that includes its own screen and does not require another device to function. All-in-one endoscope cameras also have their own rechargeable battery and a memory card to store photo and video content.

You use your phone for at least a few hours daily, so seeing a black spot there is unpleasant. You can’t comfortably watch movies or write messages because you see that annoying black spot in the corner of the phone. The good news is that you can fix it! Read our troubleshooting guide on how to remove black spots from the phone screen and follow the expert advice we share.

A black spot may appear due to dead or stuck pixels and strong external pressure. If the phone is placed in your bag along with many other objects, you may encounter not only black spots but also scratches. It’s better to keep the device in a separate, loose pocket.

Basically, professional models are a better choice for daily use in wet and dirty environments, whereas the household models work great in dry environments and tight spaces. Teslong’s professional models are ruggedly-built and sometimes include metal armoring to withstand drops and scrapes. Professional probes - the bendable wire part - connect to the monitors using waterproof, threaded aviation connectors. Also, the probes are tougher and coated with a slick waterproof material to keep it sealed to IP67 standards.

Modern phones have a thick screen, so you don’t need to worry about pressure in ordinary situations. You can use your hands and stylus freely. But beware of other objects. If they are big or heavy, they could damage the display. So don’t lay massive things on your phone.

Our newest specialty camera probes are available with triple lenses - one forward and two on the side, oriented 180 degrees apart. The triple lens probes are ideal if you are inspecting in places where you need to look sideways, but might have difficulty turning the probe. For instance, if it has maneuvered through a hole or around some corners, it won’t be very easy to rotate - the extra side lens allows you to see more.

Teslong’s fixed focus probes are ideal for tight-access applications because they are so small in diameter - down to 0.153-inch (3.9mm). Teslong’s auto-focus lenses are larger in diameter - ½-inch (12.5mm), but the larger size gives them the benefit of an auto-focus system similar to one found in your mobile phone device. Fixed-focus lenses are optimized for focusing on objects that are ½ to 2-inch away, whereas the auto-focus lenses can focus on anything from ½ inch to 100 feet or even more.

Teslong’s household models capture the same high-quality video and images, they just aren't built to withstand the rigors of daily, professional  use. One big difference is the camera probe interface - these monitors use a USB-C plug to connect to the camera probe instead of an aviation connector.  These camera cables are still sealed to IP67 spec, but they feel more flexible and are thinner, which can actually be an advantage when accessing tight spaces.

The phone can get a few new dark spots if someone sits or steps on it because such actions create excessive pressure in some screen areas. That’s why you can have a black spot on your iPhone screen. Android devices tend to have the same issues. Moreover, your phone can break due to excessive pressure if you own an ultra-budget (below $200) Android device. You should realize this threat.

Sometimes phones have internal pressure: from swollen batteries or other broken parts. It also could lead to black pixels. Find the source of the problem to fix it. If you don’t have the skills for this, go to the nearest service center. But be ready to pay $50-100 to repair your device.

Try another software hack if you are confident that you have a “stuck pixels” issue. First of all, restart your phone. This action often solves minor software conflicts, one of which is stuck pixels.

Pixels also can get stuck. It’s a software issue that leads to a black spot on the phone screen. Your phone gives instructions to the screen to turn on these tiny bulbs in the proper order. Sometimes software messes up, and pixels get the wrong color.

A USB endoscope, or borescope, consists of a camera probe and USB cord. This type of device must be plugged into a smart phone, tablet, PC or Mac computer to work, it doesn’t have a battery or memory - photos and video would be stored on the device it is plugged into. USB devices are not usually compatible with iPhones or iPads because iOS devices do NOT have USB. If you have an iOS device look at a stand alone or WiFi compatible device.

Turn on the brightness of your screen to the maximum level, lay it on some stable surface, and wait until the video ends. Check out your phone shortly after. This action should help to fix a black spot on your phone.

It is the most common reason for black spots on LCD phone screens. The only way you can fix it — change the screen to brand new. Every LCD screen had thousands of pixels. Each one has three tiny bulbs: green, red, and blue. And when some light bulbs refuse to work as intended, you get a “dead” pixel that looks like a black spot on your phone. There are two main sub-reasons for this screen issue:

When you find your phone screen turning black, inspect the device to find the source of the problem. If it’s a software issue, use the “pixel fix” tool, restart the phone or do the hard reset of the device. If it’s a hardware issue, change the broken component. It will fix your screen.

With a flexible and sturdy design, the camera cable can easily be bent but maintains its shape, enabling you to easily access hard-to-reach areas.

LCDs have a slightly different construction. They are made from tubes that hold the crystals. That is why your LCD is never totally black. It has a mild illumination that you can see in a dark room.

Sometimes the phone “forgets” how to turn on all three bulbs in the pixel. That's why it can be black. Stuck pixels look like tiny dots that keep their size without growing.

It’s important to note that although the screen sizes and resolutions are different on some of our endoscopes, they all record video at 720p resolution or higher. The resolutions you see on the screen can range from the smallest 854 x 480p resolution, 4.5-inch screen up to the 1280 x 720p resolution, 5-inch screen. Obviously, larger screens are going to give you a better view of what the probe sees so if you need an inspection camera to perform on-site inspections and solve problems right away then you’ll want the biggest screen. If you are more interested in the recorded video and photo content, then a smaller screen should work just fine.
