Hello XDA.
The screen on my LG G3 Verizon (vs985) has been acting weird and I really would like a second opinion about if I have a screen issue on my hands or if it is a motherboard problem. I included pictures below.
Screen responds to double-tap-to-wake, and buttons still work. I'm able to turn phone off by pressing power button (as long as it normally takes to display Power Menu), then tapping on where the Switch Off button ought to have been displayed. Apparently, motherboard sends stuff to screen, but screen unable to visibly display it.
I've been using motherboard since it was bought new 6 months ago so I really doubt it's the motherboard, but I could be wrong. Screen is over 4 years old. The best way would have been to try another trusted motherboard (if screen is still not normal, then it's DEFINITELY screen's fault). So in the absence of such a conclusive test, I would appreciate opinions.
Thanks.
Pictures (L-R): When booting (picture taken with flash), when booting (picture taken without flash), after booting into Android, phone charging with screen switched off.
SOLUTION: It turned out to be a screen problem (screen was replaced and voila!).

Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new
I had an odd issue with my lg, as it was how i bought it. The screen was never able to do full brightness. I eventually just bought a new screen frame for the phone, and well. Now that i got it installed. I get no buzz, no lightup, nothing. Tried plugging it into the charger, holding the power button for many more minutes then probably necessary, and pretty much any possible button combination. Is it possible the board somehow magically fried when I replaced the screen frame? I'd certainly hope not, and hope this is something i can manage to fix. I've also tried using the old screen frame, and it yields the same results as the new frame.
My phone was working fine when I went to bed last night. I laid it on my night stand and this morning I noticed I couldn't get the screen to light up. The blue LED was blinking like I had messages. The Menu and Back buttons light up when I press them, and I can even hear when someone is calling me, but because the screen will not light up, I can't answer. The phone screen is in near perfect condition, not a scratch or crack on it and I also have a cheap protective screen over it.
Hoping it was just a glitch, I removed the battery and held the power button for about 45 seconds and powered it back on. Same thing, black screen during the entire boot process, no logos or anything. I also tried to boot it in safe mode with same results. There is only one time that the screen shows any signs of life and it only happens when I first power it on. In the top left corner for a split second, where the usual "Bootloader is unlocked" message appears, it displays a small rectangle of colored artifacts inside that small message area.
I assume the LCD went out, but I'm concerned it could also be related to the GPU or other hardware, and so don't want to spend a lot of money buying a LCD if it's something else. I can still connect it to the PC, so I'm hoping someone knows how I can test the hardware from the PC, or at least recommend something. Right now the phone is ringing and I have no idea who it is...this sucks!
Galaxy Note 4 SM-N910V
I have weird problem with my phone.
First i need to note that, the phone has third screen mounted for now. I have that problem on all 3 screens. Original screen had this problem, then i changed it after cracking screen. After one month i cracked second screen and last day i mounted new screen. The problem is - sometimes (maybe 1-5 times per day) touch (i mean screen + hwkeys on it) is unresponsive until reboot. Touch is never hanging up when is turned on. I doesn't have ghost touch or sometimes like this. Touch is turning off always when i unlock phone with key or fingerprint and i need to reboot device with pressing power. Then it's always working fine.
Anyone has that problem? It's my second lemax because i sell first after problem with camera (no focus, hardware damaged because when i shocked phone it's sometimes started working). Sorry for my bads.
What i tried:
-flashing new firmware (but i dont remember what firmware i have now)
-flashing new custom rom
-flashing phone in 9008 (i need to do that after changing fingerprint sensor)
-changing screen because i cracked two (problem is on 3 screens)
-noted that problem is always. Nothing matter with phone temperature or cracks.
I have hotair and i can reflow IC but i don't know which IC can be damaged.
