Pixel Discoloration Possible Flex Cable Issue - Nexus 7 Q&A, Help & Troubleshooting

Hi All,
I just replaced my Nexus 7 screen for the second and last time. First time went without a hitch everything worked great. This time everything went without a hitch until I booted the tablet on with the new LCD/Digitizer assembly. The touch on this screen works, but I am getting some discolored pixels and a line in the middle of the screen that runs up and down if you are holding the tablet vertically. Pictures are attached of the phenomena. I read on ifixit it might be the Flex cable as someone described pretty much the same scenario and replaced the flex cable and got it working. Below is the quote from Ifixit.com If anyone has any insight about this issue that would be much appreciated. It is bearable to use. I really do not think its the assembly itself but rather something else like the flex cable which was not replaced new when I reinstalled it. I am still using the same cable from factory. Also the screen displays a lot of things with perfect resolution and the pixel discoloration seems to move from spot to spot and not stay in one location as dead pixels would behave. Thanks again in advance.
"I bought the LCD/digitizer on Ebay, the UK sellers are the cheapest.
After some forth and back mailing (the wrong address was used so the screen was shipped twice) I received it. The disassembly went smoothly although it took me a while to find out that the flat cables were locked in place with a retaining tab. Therefore I busted the data display cable. The screen came up in two halves, lots of snow, yellow or red. After straightening the display cable the screen was perfect but bending the cable back in place brought back the snow and discolorisation. For 10 Euro a new cable (also Ebay) and it works like a charm. Total cost 85 euro, 75 for the screen and 10 for the display cable.
Thanks for the guide."

lcd white screen / * HELP * connecting MOTHERBOARD - Wing Herald

i have been a member , but mainly use the site to get details & at one point tried to OVERCLOCK my phone (didnt go to well)
that said i HAD BROKEN MY LCD screen last week on my
Tmobile Wing / HTC HERALD...
i searched many sites & finally came by a
ebay seller who sold me an LCD screen (w/ digitizer) for around $50 -->
I also was given a t6 screwdriver free.
i got the SERVICE MANUAL THATS ALL OVER THE internet for the wing (apparently its the ONLY SERVICE manual on how to dissemble the wing)
-- I FOLLOWED THE DIRECTIONS & WAS ABLE TO REPLACE THE LCD ITSELF.
I put together the phone in reverse to the manual & nearly exactly.
& then i got the WHITE SCREEN when i turned it on! --->
after messing around i figured out it was the MOTHERBOARD to LCD connector part ...
but i tried sticking it together with tape & it does not work
(I LOST THE YELLOW TAPE THAT WAS ORIGINALLY ON IT)
IT ONLY WORKS IF I USE MY FINGER & APPLY FIRM PRESSURE & still the color w/ dif. pressure [applied] FUGGs up.
(which would be impossible to do if i wanted to use my phone) --
so i don't want my $50 dollars spent gone to waste ....
'
DOES ANY 1 HAVE ANY SUGGESTIONS ON HOW I CAN MAKE IT STICK together
or FIX IT PROPERLY!
again i checked & it is the connector cable that travels from the LCD to the main/motherboard that causes the problem.
this is the last place i can turn to before i have to go to an OVERCHARGING cellphone store to fix it (even after i supply everything to fix it :smh:

Paint chipping on battery cover

I just noticed today that paint had started to chip off my battery cover right next to the power button. My phone hasn't been handled roughly, so I'm not sure what happened, but that whole area chipped off just recently. Now it's starting to bother me...

Notice the two chips directly next to the power button slot.
Has anyone else experienced this? Does anyone have any ideas for touching it up?
I have two small chips on the bottom corners. I have been debating putting a tiny drop of crazy glue or maybe clear nail polish on the spots to keep the area from continuing to flake away.
I used to own a Volkswagen that had the same soft touch material all over the interior controls. It looked great and felt high end, but it would always peel off. The following model year removed ALL soft touch from the interior for this very reason. It just doesn't hold up well.
Its only a matter of time until it happens to our phones. Enjoy it while you can!

Happened to me to (on the bottom).
Got fixed when I sent the phone in for a replacement (for another issue)
It gives the phone some character like Stevie ray Vaughan's guitar...
My proclip car mount put 2 chips in either bottom corner of my phone
I actually have an extra battery cover. I had bought a new one cause the clear plastic "lens" for the camera cracked. Unfortunately the new cover didn't come with the lens.
If u call HTC they will send u a new battery cover for free

If i press inside the red area (including home button) it wont work and its just like i pressed the near side, like icons in the left or right of that red area.
I tried full data wipe, cache and dalvik, tried flashing newer sbf and no good.
Do you guys have any idea on it?
Thanks
Bad news bro.
I'm pretty sure its a hardware problem, the screen must be damaged...
So i need to replace it?

Better to get a new phone =D
a new phone is your option coz replacing the screen would cost you alot while you can get a better phone in a few bucks more!
New screens are available on amazon for 12 pounds (at least I spend this much)
However It may be a signal cable. They starts from 30$ on ebay
There are disassembly videos on Youtube.
I had a similar problem and I did the replacement two months ago and it works.
I bought the screen digitizer with tools on eBay.
Be sure That you have a torx3 beca use it didn't came on the tools! ;P
I had the same problem... I sent to the Moto Assistance and the had to change the touchscreen for a now one.
Good luck!
Not the cable. If the cable was damaged, it would shut down the entire screen. It's a problem with the digitizer. Hopefully for you it's relatively easy to exchange it, but you'll damage the camera sticker, the top panel of back side, above the battery and the speaker grid sticker (all of those are glued to the phone) in order to open it. Doesn't matter the way you take them over, you'll always damage it. Might wanna buy some of these on ebay too, although I'm not sure they sell it.
I had the exact same problem with my first M2, it was still under warranty but Moto took sweet 15 days to exchange it, and they returned my phone with a stuck volume rocker. Had to send it again, they took more than 15 days this time, so I asked for a replacement.

Fix for Sleep Of Death!

Did your tablet screen go out? Does the backlight still come on, but the screen shows nothing? Can you hook it up to a TV, and the picture comes out fine? If so, it is most likely a loose cable, and can quickly be fixed by you, without RMAing it and waiting weeks or months. While the guide should be spot on, and you aren't going to be harming the device in any way, I'm still not assuming any responsibility if you destroy your tablet. You will first need to take apart your transformer. There are plenty of guides out there, so once you get the back off, come back here!

Hi stuntdouble,
Two torx screws have to come off first, these are part of what holds the bezel down.
After that you need to use a guitar pick from the back to lift the bezel up...best to get all 4 corners up and keep sliding..as soon as it wont slide lift it out and back in again a bit further on... it absolutely destroyed the pick by the way..lots of sharp edges in there.
The bezel will then come off from the front of the tablet. Just be careful and dont force it, Around the 40 pin connector was the biggest pain.
The back cover is held down by 4 screws on the top glass, and umm if I recall about 10 screws behind where the bezel . It basically then falls off once all screws are off with not to much effort.
There are also no security stickers over any of the screws anywhere inside the tablet

Take a look at the bottom, you should see a strip with a bunch of multicolored wires coming from the battery. Underneath it, and near the bottom of the battery you should see a ribbon cable. Here's a picture, the display cable has a flashlight shining on it.

Try pushing that into the slot a bit and see if that fixed it. If not try pushing on a few of the other cables, if this doesn't fix it, then I would suggest you RMA it, although I really think this will fix it for you. This has happened twice to me, and each time, pushing cables a bit seems to do the job.
Best of luck on fixing it and post your results please!

Should I try to save my black screen nexus 4?

Hello people.
I need help to decide if I should try to save my nexus 4 or not. It has been dismantled for the past half a year and i recently got it to show signs of life after battling the steady red ring of death. (Was simple by the way, just used a wireless charger for a couple of minutes) But if I turn it on, it vibrates, the screen lights up and that is just about it. So i have no idea if the phone itself is functional. Some of you might tell me not to bother with such an old phone, hell, they aren't even sold anymore. But this phone has stuck by me through thick and thin, and has a sentimental value. I nearly jumped of joy when it showed signs of life after such a long time. I am not a rich man, so i need to manage my finances. Screen replacement would cost me 25 pounds, back housing would be another 10, but what if the phone is still not functional? Is there any way I can find out if I should take the gamble?
Some info -
I am not entirely sure if there is an OS currently installed on the device, as I was experimenting quite a bit before the battery run its coure.
I am also missing one of the connector things that are circled (there is one and a broken spot where another one should be) but i have no idea what it connects to. The little peg itself is safe and sound in my possession, if it can be welded back. It connects to whatever is under the power button on the back housing.

The screen is cracked in three places, but was working the last time I remember. But there have been many (and I mean many) dis and re assemblies since then.
I probably love this phone more than my friends and family. Just want my favourite piece of tech to be my companion again.
Could the red light be due to a dead battery?

Thankls for the reply. The battery is new and the red light issue is sorted. The phone just doesnt do much more other than vibrate and light up the screen. How do i know if it is still worth investing money in is the real question.
