[Q] Horizontal white stripes on the display - G Pad 8.3 Q&A, Help & Troubleshooting

Hi guys,
I just got my brand new LG G Pad 8.3 a few hours ago and I started to try it out. When I installed and started a game, the tablet just shown a lots of horizontal white stripes on the whole of the display equidistantly. I immediately exit the game and I've noticed that the stripes are still shown. I restarted the device and the stripes are still shown on the boot logo as well. After that I did a "Factory data reset" but nothing happened.
These may helps:
- When I started the game, the battery percentage was around 12 and it was plugged in. When I done the game it was 8%
- The game was Real Racing 3
- The phone in brand new, I didn't root it yet, so it was absolutely factory.
Any idea?

If you still have those stripes in boot logo it is more like a hardware problem not software, ask for replacement while you can.

Thanks for your answer.
Yeah, I still has them, nothing changed. I've written to the seller but they didn't answer yet (I hope just because of the weekend).
Update: I could replace it, even if they wouldn't really want to reply to my messages. Now works well.

Hi today as usual i was playing with my phone ,battery under 15% appeared.
It was on 12% and i recharge it
After about 2 hour i came back to unplug the charger. I saw the phone is off and it did not turn on !
I take out the battery and Turn it on
But when i turned it on the screen did not showing the colors correctly it was like when you change the color depth in windows from 32bit to 256colors
And a big problem with black colors
Actually the black colors were shown in red And the at&t boot logo signs was remained in screen.
I dont know what happened and the charge level was in 60%
After about 10min the screen became better from top sides but i could feel the att logo in screen
And after 20min it was clear and every thing was ok .
It was frightening and i thought that it damaged.
did anyone had the same problem before?
What happened to this phone !?
I did restart it many time and recharge it. My nitro seems to work fine.
Is the screen damaged ?

I'm having the same issue and having a really hard time finding any info on it. After booting it looks "ok".. but during boot it looks as this person described it: windows in 256 colour mode.. Very strange. My phone drained down to 0% today during work, and I just tried plugging it in and turning it on.
Hopefully this goes away. Running CM10.1 RC5 with Wind 2.3 and I have flashed the new adreno drivers and changed max layers to 2 in build.prop to make camera buttons display properly.
i switched back to modded ics stock after cm10.1 had 3-4 nightlies that didn't even boot and all kinds of bugs in the last 3 weeks, i'm waiting for a stable release to come out before i switch back, i recommend switching back to stock while they deal with recent issues, that's just my opinion tho. u guys could try backing up ur cm10.1 and flashing a stock rom to see if the problem is fixed, even if u decide to switch back to cm after, it's worth a shot.
if flashing a cwm flashable stock modded rom fixes the issue you might want to consider doing a full wipe and going back to rc2 or nightly 19th-22nd of may before the issues started

weird reboots lately - blue screen

nothing exactly meaningful, just wanted to mention in case other people had similar experience.
well also it may have implications after the next OTA / post-root-if-that-happens
for reference: to be safe, for a while now I have had both of the known IPs blocked on my router.
- maybe a week ago, tried to scroll into Home->Recent and got a solid blue screen for 5-10 seconds. didn't touch the device, it auto-reboots, then everything ok. version number unchanged still etc_02.etc like we all have.
- few days after that, Prime TV was playing and kept playing fine, but usb went sideways. reconnecting usb, power looked ok but still nothing. tv app kept playing 100% fine just no HID. stupidly did not try the remote. recycled power, and got stuck at (white-logo)amazon screen. power-off, wait a while, tried a few more times and always stuck at (white-logo)amazon screen.
-- removed the 2 blocked URLs from my router and booted, everything back to normal. (version number still same etc_02.etc)
wasn't even going to bring all of this up, who knows I may have a flaky KFTV, but then
- today got the solid blue screen again trying to scroll Home->Recent*. as before, box eventually rebooted itself, without having to do anything, and everything normal again. (and this with both IPs still re-unblocked)
if nothing else reminded me to re-block both URLs lol. but it is a very small and random sample size so far.
semi-weird: the first blue screen, and the usb breakage, both very hot days here, it almost could have been temp-related (but box did not feel warmer than usual) - but then blue screen today is bad weather / cold here, so yeah probably not.
*since it happened same way both times, could easily just be some bug about Recent, or in the KFTV Launcher

LG3 wont boot + Blue screen

Hello, i faced a serious problem this evening, just after i finished a call phone, the screen of the phone went Blue and then it went off, i started to put it on again and then it showed the screen with LG and then it went black no boot at all. i removed the battery and i tried again and still the same, so i tried to remove the battery and put it again and plug it with the computer, it went on with charging battery and then suddenly went to blue screen again.
So i tried to put the recovery mode with power down and on/off and it worked i got the recovery mode screen with factory reset but it was only with factory reset, i tried it and then i put yes and it reboot and then after LG screen, it went black again....
so i tried to put download mode with usb cable but it wont, always i got the blue screen. what should i do, where is the problem exactly for people who had the same problem ? the batterye ? the motherboard ?
anyone to help ? i changed the battery and it wasnt coming from it, and the phone showed others anormalies like sometimes u can charge the battery and you see the % and sometimes it goes blue screen and shut down. anyone had the same issue before ?
My LG G3 randomly started giving this problem for 3-4 days till it went completely bad. It just wouldn't get past the Blue Screen. Since I had to take a backup before taking any further action, I have been able to get it up and running for very short durations by keeping the cell phone in the freezer for an hour or so. Yes. I am not kidding. After it freezes, I can get it up on about 5th or 6th attempt. Sometimes even more. Be mindful that the battery is now showing a red humidity marker due to the freezer.
I am thinking of asking LG to repair it. What a piece of crap. Its only 18 months old for me.

sudden Graphics/Screen glitches (new phone)

Dear,
So I have my phone for 2 weeks now and suddenly my screen creates these black/green/white/blue lines on my phone and my phone screen was full of it, I couldn't see anything so I restarted the phone by holding my power button, it restarted and on boot some of these lines occurred again. I decided to download a game to test my phone (Need for speed No limit) and I saw like some graphical glitches and also suddenly my phone went to invert colors without me turning the option on in quick settings or accessibility.
I'll take a look how often I get these and will probably just go to the store where I bought it, or is there a quick for this?
Still on Android 6.0 no root.
It's most likely a hardware issue and you're best to return it to the store you got it and get a new one.

Does this happen on boot animation too? ( the google and android loading logo ) If yes, then it's probably caused by faulty lcd and/or lcd cable. If not, then something is wrong with the software.

I am experiencing this issue as well. I get it most of the time on boot. If i leave it on the glitchy screen long enough, the phone will just reboot.

Oneplus 3 with display issue, or motherboard?

Hi all!
My father's Oneplus 3 (A3003, 64gb) died a few days ago while he was waiting for his new oneplus 6 (if only it died after migrating... sigh), and i'm trying to troubleshoot it.
The display went dark after a night, no led, nothing. He plugged it to a computer, and a device called HS-USB Qdloader 9008 appeared in the device manager.
I thought it was bricked, so we followed the unbrick stepps (even the full package).
Nothing happened on the display after reboot, black screen after a short vibration, then a few minutes later another vibration, and so on...
I let it alone for a few days then tried again to see what was happening, and went again with the unbrick process. This time it completed successfully and i was able to see something on the display, but very very dim!
It booted to the stock OOS, then it rebooted right after arriving on the OOBE, and it froze while booting after that.
Again i let it alone for a few hours, and tried again, outside in the cold. This time it "worked", with the very very dim display though, i could barely see what was happening on the screen, but i was able to set it up including wifi and play store, and i could do a benchmark using geekbench successfully (score was on par with other OP3).
I went inside and tried again a few hours later, and it froze right after launching the benchmark, rebooted and froze during boot. Then i could do nothing to make it boot again (while it was warm anyway).
tl;dr : It only "works" when it is cold, and the display is barely readable. I'm thinking it could be the motherboard or the display, but would a display issue cause the reboots when getting warm? Seems weird to me!
i attached pictures of the failing OP3 next to my OP3T to highlight the display issue, the "band" visible on the 1st picture is not visible to the bare eye, only on camera and it "moves", no idea why this happens.
EDIT : i was able to unlock it while it was "working", if it is of any importance...

Looks like a Display issue. It is possible that it triggers the booting issue, though I am not sure about the "hot & cold" issue. May be a loose connection. Did it suffer a fall in the past? If you are upto it, check some videos on opening the phone and check and clean the connections. It may help.

Thanks for your answer, i just looked at the requirements to open it, and i need a T2 screwdriver, which i do not have yet, the smallest i have is a T3 unfortunately.
I think it did fall a few times, but no issue right after at least. It may have loosen the connections though, you're right...

You just need to Flash Latest OOS
this type of issue was happened to me 2 months ago, i successfully recovered display by Hard bricked method
first of all i used Qualcomm hard bricked method to get my 1+3t to working condition (display was as you showed in picture) with Qualcomm Tool's Old builtin firmware
then i I flashed OOS 5.0.4 and its all done with Bright Display. I did not opened the phone.

Thanks ! I sideloaded oos 5.0.8 and now the display is fine !
It still freezes when getting warm every time, if I put it outside in the cold i can do benchmarks without issues, but as soon as I try the same inside it freezes. Since I already unbricked it, it seems hardware related but outside of the motherboard, what could be the reason ? Can the battery be responsable for that ?
The freeze happens very quickly inside, it does not get hot, barely warm at the top of the screen.
as far as my idea is concern you have another 1+3/t, to confirm battery issue swap your motherboard or battery with the other one, it'll confirm the battery. other than battery issue check lose connections/rust and thermal issue, if got any clean connection strips then reconnect. my 1+3t never got hot from any side ever.
