[Q] Strange horizontal bands of colour on display - Galaxy Note 8.0 (Tablet) Q&A, Help & Troubleshooti

My tablet is displaying horizontal bands of colour, the same colours as what should be showing on the screen. For example, if I had a red, white and purple background, it would show red, white and purple lines across the screen. The tablet is still fully responsive even when this is going on (can still pull down the menu, touch to turn off, etc.). Sometimes just turning the screen off and back on gets it working right again, sometimes it takes a few taps on the back to the tablet. But once its working again, it stays working until the screen is off again for awhile.
I can use the tablet for hours with everything functioning as it should (using it now to type this post). After leaving it for an hour or two, I wake it up by pressing either the home or power key and the lines will be back. Even if it's shut down for a while, when I turn it back on the lines are back, and they appear right from boot, or even when off and charging, the green battery charging icon turns into green horizontal lines.
I've already cleared the cache, it was just factory reset, I've had the back off, disconnected the battery and reseated what I think were the screen connectors.
Any thoughts as to what is wrong and how I might fix it would be appreciated. It's a Note 8, 4.4.2, stock, not rooted.

I think it needs service, it's a hardware problem

You can use a HDMI adapter to connect to a TV or using Screen Mirroring Function to see the display on TV. If it's normal on TV, your LCD is defective or the LCD cable gets loose.
In order to get the LCD cable, your main board has to be removed as the LCD lies under it.

My screen wont turn on. Help

Just yesterday i noticed that my phones screen was bugging out, eg. if it bumped into something or set down on a hard surface the screen would
flicker, similar to static, but only for a second. later that day, the screen went black, i thought the battery was low and did a quick battery pull
and it booted up normally. it happened again an hour or two later the, black screen that is. when i got home i really noticed the static as it was
placed on hard surfaces: the table, desk, etc. since it was low on battery i plugged it in to charge for a bit, when i came back to tun it on i was able
when when the screen timed out i wasn't able to turn it back on, i tried the battery pull but nothing, At that point the boot animations wouldn't show
the only things that indicated that the phone was turning on was the notification light and the pouch buttons. when it is "on" i'm able to swipe to
unlock, hold down and get the feedback of when you want to move an app or widget. The phone is on but the screen is black. oh and when i try
to go into recovery or download mode the screen is still black,
im wondering if its a busted screen but the thing is there are no cracks or anything on the screen maybe a few minor scratches but that's it

Note 5 with serious issues: Screen dim (Almost unreadable), battery icon center

I was given a Note 5 to fix. I do not know the history of the device. If a Android update was attempted or why it is needing to be fixed. It presented with a very dim (almost unreadable, except in completely dark room) screen. I have wiped cache and master reset the device. I can see that the powered off battery icon is center screen all the time and it is solid black. I cannot power it off via the normal power button but I can power it on. I can power it off using the power button + volume down. The touchscreen is responsive and not cracked or broken at all. The back, multi and home buttons react normally to touch and light up. When plugged into power or PC, it does charge and will show a red LED when charging and a green LED when battery is full. The sounds are normal as far as I can tell. I cannot get the screen to change when I swipe or press a center button. I was able to get a picture of a begrizzled man peering closely at the phone trying to figure out what the hell the problem is. So, softwarewise, some of it seems to be working. But, I cannot figure out the dim screen. Like I said earlier, there no cracks or even scratches in either glass, front or back. The bottom portion of the stylus is broken, but I was able to use a tiny phillips head to stick up in the open area and it working. I get a sound and vibration when it is removed and inserted.
Any ideas?

For some reason when the phone detects that the battery is under 5%, it will forcibly dim the screen until it is charged above 5% or plugged in. Maybe the phone thinks that the battery is at or below 5%. Have you tried plugging it into a power source to see if the screen lights up?

Update #1 - Somehow, without knowing how, I managed to turn on an Accessibility option for the phone to tell me what buttons or actions I have taken. Unfortunately for it is in Spanish. I guess I should have taken Spanish in high school...

Yes, I have plugged it to the wall, I have plugged it to my PC and I have wireless charged it. It seems to charge to full as the red LED turns green.

Lg g3 screen stays black after reboot, but responds to touch

My wife's phone looked completely dead this morning, so I pulled the battery and then rebooted. The led did its usual start up pulse but the screen remained black.
Double tapping to wake, then tapping the centre of the screen where login field is, then tapping where the keyboard is, results in haptic feedback, but the screen never turns on from black.
Tried holding down + power to boot into recovery, but no idea if it works. No response from the screen.
Anything I can try? :crying:

Its the faulty motherboard chipset issue, same as me.
Take the phone apart and place a piece of plastic or something on top of the display ribbon connector underneath the battery. That solved this problem for me.
Seems to occur because the board in the g3 has too much space to flex etc in general usage.

Dark area on screen ONLY after sleep

Hi folks!
I've got a very weird issue with my P-600!
Yesterday, I noticed a dark area in the left corner on the bottom of the screen.
At first, I thought a LED line was dead on the backlight panel. No surprises, it's a 10 years old device...
To confirm that, I rebooted the device expecting to get the same issue (dark corner anyway, anytime) but it became even more "bizarre": after getting into system again, the dark spot was gone but the device was unable to revive the screen after going into sleep mode.
No matter if the screen was put into sleep by inactivity time-out or by pressing the power button, when the screen became black, it stayed black.
But with apps still running in background: for exemple Spotify was still playing music.
The only way to get the screen on back again, was to force a reboot by keeping the power button pressed down.
After reading many posts here and on other sites, I found some talking about the "Android Black Screen Of Death" and some tutorials on how to fix it on Samsung devices. So I opened my Tab, unlocked all flat cables, waited 10 minutes or so and then reconnected everything.
Well, it did it but only partially: now I'm a in quite "mixed" and unexplainable situation.
The screen works again, I can put my Tab to sleep and get it on again just pushing the power buton.
BUT...
The dark area in the left corner comes back again, only after sleep mode!
If I reboot the device, the screen is perfectly enlighted in all its surface, but it will get again that dark spot in the corner after screen sleep. What the heck... ?
So it's not clear for me how to definitely fix it.
Should I replace the entire screen? The flat cables? The battery?
Any help to understand what's going on will be greatly appreciated!
