Nexus has grainy screen - Nexus 7 (2013) Q&A

Hey all; I got a Nexus 7 this past December and everything was working great until yesterday.
I took it out of my school bag and when I pressed the wake button this happened:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now whenever I wake up my Nexus the same thing happens. Sometimes it goes back to normal after a few seconds, but it continually freezes or has random slow downs.
I reset the device and erased all my data and whatnot, but still the same has happened.
Any suggestions?

What ROM are you running, stock or custom? Try reflashing a ROM (let us know if you aren't familiar with that) in case something's corrupted. Hopefully it isn't something with hardware.

This should be a hardware failure.Take it to the service.

@Pandae: Everything was stock. @GeoVali99: Correct-o, sir!
Ended up being a hardware issue so I'm getting it repaired.
I appreciate the words though!

Hi!
I've got the same problem.
Can someone tell me how to fix that Problem by my self?
I have no guaranty left...
Thanks!

Not a big deal. The LCD is fine. What happened in my case when I got exactly the same screen is that the amber ribbon (LCD to motherboard) seated wrong, and I bent a pin on the motherboard connector out of shape. You open the back cover and reseat it, but make sure you do not damage the pins. In other words do it very gently, do not force anything, and monitor it all with the help of a magnifying glass.

[Q] Semi-damaged XDA Orbit

Hi everyone,
It is almost 2 weeks my XDA Orbit is not working properly. The first time it hanged-up during a call and afterwards it took me several resets to bring it back. During the system load the screen was changing colors and freezing, sometimes completely white, sometimes with some colorful stripes, sometimes solid violet. After several reboots I couldn't turn it on at all. I took it to local service, where they told me that the problem is with boot loader and fixed it. I took it back and have the same experience. I have flashed it with original ROM, both from PC or SD card, but the same problem exist. I am assuming that the issue is in a hardware defect. I know that it is the time to get rid of this PDA and get a new one.
Anyway... Is there a tool available for testing HTC hardware (CPU, flash)???

possibility the battery gone or the lcd.
buy a new battery, theyre only cheep so start there..
leave it off while charging, green led when done.
if its not your battery, i think its your lcd..
best to open the device and check your lcd is connected properly..

Opened my Orbit recently, the connector is in place. I would assume that the issue is more in battery then LCD. The battery surface is lofted.
Assuming that it's a battery issue - should the same happen if the device is always connected to external power supply?
...
LOL
get a new battery dude..
dont turn the device on untill the new battery is fully charged.
a simple fix hopefully..

[Q] No Bluetooth/Wifi after Charge board replacement

The charge port on my phone went bad and needed to be replaced. The replacement went smoothly but now it I have no bluetooth or wifi antenna. I get maybe 1 bar indicated if I am a few feet from a wifi hub and bluetooth isn't working at all. I thought it might be something to do with the new charge board so I replaced it again with the same results. If anything it might be even worse now. Any tips on what I should be looking for that is wrong?
Sounds like you broke one thing fixing another . If it's physical damage you need to go backwards and check all your steps and see what happened.
If software issue try reflashing modem.
Pp.
I found the problem and it, which is a simple one, The fix though I think is going to be difficult. A very, very small capacitor is missing from the board. I must have hit it during the charge board change. If I knew the value of the cap I could probably solder a new one on. I have no idea how to find that out though. Here is a picture of the missing part.

A lot of internet digging has turned up the spec on the missing cap-
Samsung part #2203-006665
0.0022NF,0.25PF,25V,C0G,0603, C-CER,CHIP
That particular number is out of stock everywhere but I was able to find an equivalent from DigiKey.com
Samsung #CL03C2R2BA3GNNC
Digi-Key #1276-1403-1-ND
I bought 10pcs @ 2 cents a piece.
Good luck with the soldering,
In case that doesn't work for you maybe this will work for you.
Pp. Lol
Soldered in the microscopic capacitor yesterday and phone is back to 100%!

S4 mini digitizer replacement issue

Hi all, yesterday I replaced the digitizer on my son's s4 mini, first time I've attempted this, but seemed a fairly straightforward process, took the phone apart without issue, placed all the relevant parts into the new digitizer and reconnected everything, put the battery in and powered up the phone, and the screen seems corrupted, I've taken a picture to show the issue.
Any help that anyone can give will be greatly appreciated.

I wonder if a flex cable got partially torn in the process? I have never done such fine work, especially not to an S4 Mini, so I'm not aware of all the pitfalls.
Best of luck though!
Nothing that I could see, I've checked all connections and cables 3 times, and they all seem fine, I have sent the ebay seller that I brought it from as I fear the screen is faulty, but as yet no reply, thanks for your message ?

(solution) Ghost touch, ramdom turning on and off screen

You need to make sure its not app, rom, kernel, related, try booting in safe mode to see if problems persits if no then is app related.
If you wipe and reinstal rom and problem persist then this might be help full
Before anything else i sugest you look for zenfone 2 dissambly vids so you get to know what you are going to be doing, it is easy.
Before telling you the solution let me explain my phone symptoms:
1) Ghost touchs, be aware if you have selected show cursor coordinstes or show touch, much of the times this ghost touch doesnt appear.
2) Phone screen starts turning on and off by itself. This is very annoying I tried turning off doble touch to wake but this didnt help.
So what is the solution?
You need to open the back of the phone unscrew everything and then in the charging usb port you need to make sure that the back part of this pice doesnt make contact with the metal back plate. What I did is to use an electrical pice of tape that cut. And simple as that my phone working normal again.
Remeber to screw everything tight as possible.
Pd: i didnt took any pics but im show what part of the phone im referring
Hope this helps have a great day

Screen dead after rom flash

Hello, i wiped my phone(system,data,cache) and flashed aquarios rom, but after rebooting my screen was not working, system booted up and i can hear volume and vibrations. But i cant locate the problem... could it be in hardware? I tried to disassembly phone and clean contacts and make sure everything is good connected. Also tried to wipe everything and flash stock 7.1.1, then 6.0.1, and still the same problem. Anyone got any idea? Should i replace the screen? Thank you

Maybe your GPU died? it's part of the CPU chip, and we know that unfortunately this CPU (SD808) is prone to fail on this device, due to heating-cooling cycles that creates cracks in the CPU chip substratum (looks like LG miscalculated the coefficient of expansion). I am saying it based on that you were flashing your device (it produces lot of heat and CPU use), and then, after a reboot the issue showed up.
But it can be faulty screen, this would be very weird (since i am assuming that you did not drop it during the flashing process or something similar) but not impossible.
You cleaned the connectors on the motherboard with isopropilic alcohol? i had a similar issue on my N4, and it was the solution.
Anyway if i were you, probably i would get some chinese and cheap screen replacement, at least to discard the faulty screen theory.
Thank you very much, i wouldnt think it could be gpu problem, but it looks like it is. I am going to give a try replacement screen. Taking into account my usage of phone, it would explain the dead gpu.
