laptop lcd screen cable factory

My wife contacted me, from the other side of the planet, to tell me that her laptop was having trouble. The screen would only work when the laptop was partially open. I told her that I could probably fix it when she got back home.

This is a common problem in laptops. The cable that connects the screen to the base runs thru the hinge. The opening and closing bends the cable and, after time, this bending and unbending of the cable damages the wires inside the cable causing shorts. Sometimes you can use the laptop in a certain position but other times it will stop working all at once.

The cables are usually between 15 to 25 dollars on Amazon and can be found by searching your computer"s make and model number. In this case, it was a Toshiba Satellite S55-B5157. If you take your laptop to a computer store, they will charge around 100 dollars or more to fix it. If you can unscrew screws, pry off some plastic pieces, unplug a cable, plug back in a cable, snap on plastic pieces, and re-screw the screws back in, you can do this. It is not as intimidating as it may sound.

I only needed a small Phillips screwdriver and a small slotted screwdriver. If your laptop has specialty screws, you will need the proper screwdriver to fit them. The only reason I needed the slotted screwdriver was to pry some of the pieces apart to a point I could use my fingers to pry the rest. You will also want to wear safety glasses, sometimes small pieces of plastic could go flying when you are prying off pieces.

Working with electronics, it is important that you remove, or at least disconnect, the battery. If you skip this, you could damage not only your laptop, but possibly damage yourself. This laptop had three screws securing it in.

The frame around the screen almost stumped me. I started by prying off at the top corners. When I got close to the bottom corners, it seamed like it was stuck. I looked closer and found two tiny little covers hiding two screws. I popped the covers off with the small slotted screwdriver and removed the screws they were hiding. I was then able to finish taking off the frame around the screen.

There were four screws holding the screen to the top of the laptop. After removing those screws, I carefully placed the screed on the keyboard of the laptop. The cable was secured with tape that has to be pulled back to be able to unplug the cable. Look closely at the cable and use the new cable to determine which way you need to pull the cable to unplug it. One end of my cable had to be pulled horizontally and the other end had to be pulled vertically.

Pay attention to the routing of the cable. Make sketches, take pictures, take a video, whatever it takes to be able to route the new cable the same way as the old cable.

Route the new cable just like the old cable. There are other cables that could be damaged if you go over instead under. There are also little channels in the laptop that hold the cable in place to protect it. Plug the cable into the bottom part of the laptop first.

After routing the cable thru the hinge, plug it into the screen. The new cable came with a piece of tape attached to it. After I plugged the cable into the screen, I stuck the tape to the screen.

After getting all the covers and screws put back, reconnect the battery and turn on the laptop. If all is well you are good to go. If the screen does not work, take the covers off and double check that the ends of the cable are plugged in properly. If the laptop screen still does not work, you may have to take it to a computer repair shop.

As Usual, I made a video. Some laptops are similar but some are completely different so you may want to search the internet and see if someone has posted a video of replacing the screen cable on your model of laptop.

My laptop screen works but the touchscreen capability is gone and undetected by my laptop, post a power port replacement. Is there a specific cabling connection dedicated to the touchscreen function? If it is a separate cable or connector, maybe pressing it together might restore the touchscreen? What physical component could fail and take out just the touchscreen function? The touchscreen is not even detected in BIOS. This is a 15-0073wm with touchscreen capablity normally. The drivers don"t show up and system info says it does not have pen or touch input.0

I found the model number, on the bottom of my laptop, and then Google searched that model number followed by screen cable. The first thing that came up was an Amazon listing of the cable for my laptop. Good luck.0

Hi, My screen cable is frayed, about a half inch of it, so there"s some play in the length. I want to snip off the frayed length, then splice the two clean ends back together. Do you see a problem with that? I used to work as a cable tech, low volt, so I can do a splice. Thanks, and thanks for posting how to totally replace the cable -- I"d do that but dont want to wait for a brand new cable.0

You might be able to, but they are tiny little wires. And if the original cable is fraying, in that one spot, your repair would be in that one spot where damage is likely to happen. Good luck.0

Thanks, I"m going to give it a try. this is the first Chromebook atht his has hapned to -- I think Chromebook is notorious for placing those wires in the hinge that opens and closes the Chromebook. I smelled the frying years ago and the the computer just seemed to die but didn"t know enough then to know why. A year later I opened it on an off chance of it working, perhaps? I forget why. And in this case it worked but sporadically, like your wife"s. I believe it is the exact same cable and I"d rather give it a try myself first before doing to very close work of identifying the wire exactly, for my Chromebook, sending off for it, having them send me the wrong wire -- that could go on forever. I"ll try this first then do the work of dealing with someone or some company that has the wire i need.

Seriously, you"ve been so helpful, you have no idea. PS The original cable that frayed, or rather, melted, was from the heat of being caught in the hinge and shorting out. After a year, left alone, it had sort of fixed itself, but you know, was still damaged and caused problems. Thanks, Charles Scranford!

I had to take 3 laptops apart last week. Aside from sourcing replacement parts, I think releasing the plastic case tabs without breaking them is the hardest part of a laptop repair. I use the corner of an old credit card to pop them. A disassembly guide helps to find those hidden screws while not removing any you don"t need to, and a reminder of where everything goes when you put it back together.

Sorry It took so long to reply. I somehow missed your comment. I wasn"t wearing a ground strap, but I was bare footed. It is kind of intimidating prying up on something as expensive as a laptop looking for fasteners. My wife was very happy to have her laptop fixed.Post Comment

We offer over 50 models from CLEVO - from office devices to gaming laptops to advanced mobile workstations, which we configure and optimize according to your wishes. We only use high-quality parts, e.g. Intel, AMD, Samsung, MSI, Patriot, G.Skill, Kingston. We mainly rely on the combination of NVIDIA and Intel / AMD, as we have had the best experiences over the last few years. In addition, our models often have a very good / high-quality finish in the form of a metal housing, which not only leads to a more valuable device, but also to more stable operation of the device itself. From the Intel Celeron processor to the latest Intel i5, i7, i9 processors - 10.11.12.13 generation and AMD Ryzen 3000 / 4000 / 5000 / 6000 / 7000 processors that you can freely configure in your chosen device. Of course, the graphics unit should not be missing either, i.e. Intel UHD Graphics / Iris Xe Graphics / AMD Radeon Vega RX and NVIDIA MX 350, GTX 1650, GTX 1650 Ti, GTX 1650 SUPER, GTX 1660, GTX 1660 Ti, GTX 1660 SUPER, RTX 3050, RTX 3050 Ti, RTX 3060 , RTX 3060 Ti, RTX 3070, RTX 3070 Ti, RTX 3080, RTX 3080 Ti, RTX 3090, RTX 3090 Ti, RTX 4080, RTX 4090 / AMD Radeon RX 6400, RX 6500 XT, RX 6600, RX 6600 XT, RX 6650 XT, RX 6700, RX 6700 XT, RX 6750 XT, RX 6800, RX 6800 XT, RX 6900 XT, RX 6950 XT.

In which case, replacements can be found on-line. The only thing is to buy a cable that will fit in your laptop. Length does not have to be exact, but its always better to have a longer cable than one that is too short. You can"t cut and splice these effectively, not without good expensive tools anyway..

According to the specs you will be looking for a 40pin 2CH 6-Bit LVDS cable. I would like you to post up pictures of both connections on the cable, to confirm that it is not a proprietary socket (highly doubt it as it"s not apple).

The best display panel that this HP model could afford would probably be the B156HAN01.0 produced by AUO due to its wide viewing angle, IPS technology, high contrast ratio and better colour performance but this screen was only produced until 2013 and it’s hard to find nowadays. I managed to find this panel on eBay and after its installation the result was really good - viewing angle and colours were fantastic - but unfortunately it was not functioning in the middle (a small black vertical stripe was there). So, in the end, I installed a B156HTN03.3 which is not as good as the above-mentioned one but a whole lot better than the original LG display. Choose your best one!

jump directly to step#23 ─ in any case only after having removed the battery in order to avoid short circuits on the display cable once you will be handling it ─ and try to install the new LCD without opening the laptop. It’s quite difficult because two of the four screws that secure the display bezel are hard to reach without splitting the laptop in two but you could manage to loosen them somehow.

bear in mind that you will need to replace the thermal paste too and therefore, before starting, gather together all the tools that you will need for that too. In order to work on the display hinges with ease, we have to indeed disassemble the heatsink and the fan. You can find the standard display cable for sale on e-commerce using the following HP part number: 720536-001.

Notebook computers squeeze a long list of parts into a minuscule amount of space. Their video cabling can run through casework hinges and around monitor bezels, tracing a complex path from motherboard to screen. Any disruption of this critical wiring can cause equivalent interruptions in your computer"s on-screen display. Some of the symptoms of incomplete video connections also can point to other hardware failures. Correcting these problems can be as complex as diagnosing them.

Black or Blank Screen Even with loose or disconnected video cabling, some laptops continue to boot -- minus on-screen display, of course. When you start up an otherwise properly functioning notebook computer, you hear and see a sequence of sounds and indicator lights that proceeds regardless of whether your screen responds correctly. If your screen stays dark but your system makes its normal noises and displays no unexpected blinking lights, your video cable may not be making contact. To verify that the computer"s on-board video functions remain intact, plug an external monitor into the laptop"s video-out port and restart. These symptoms also can accompany a failure of the fluorescent or LED backlight system that illuminates your display panel.

Intermittent Video Function Loose cabling can produce intermittent disruptions of video function, especially if you nudge the notebook system or its display panel while the computer runs. These kinds of positional interruptions can plague any form of electrical connection that"s not completely plugged in or that suffers from pinched or broken wiring in a faulty cable. Because these symptoms can signal damaged as well as loose connections, they may require new parts. If your computer remains under warranty coverage, contact its manufacturer for assistance.

Garbled Display Problematic video cabling can distort or interfere with on-screen display of your operating system and applications. You may see blank areas, unexpected horizontal or vertical bands of color, or other flaws that also can materialize on a faulty or damaged display panel. Diagnosing these malfunctions can require tools and disassembly skills that exceed the capabilities and resources of the average computer user. To isolate the problem, look for service under warranty coverage or independent technician assistance.

Other Considerations Many symptoms of laptop video display failure can trace to more than one potential cause. The diagnostics involved in troubleshooting video components and connections can require complicated disassembly procedures, diagnostic tools and access to replacement parts. Unless you have the necessary experience, reference guides and equipment to tear down, repair and reconfigure your system successfully, trying to fix your computer yourself can cause more problems than you solve. Weigh the age and replacement value of your laptop against the cost of repairs before you try to find and fix what"s broken.
