Hi, I was trying to repair my friends T280 and I got the following problems on it:
1.) Entering download mode the text and the download logo appear normally but after a few minutes (or sometimes instantly) it completely disappears only remaining is the light blue background. Odin also stop and fail when it happens. Tried flashing it anyway but failed somewhere in the System.img before the logo disappeared. Sometimes the background changes colors.
2.) Charging it while turned off most of the time does not show the charging icon. Just a black screen with no backlight. But the battery is charging according to my USB tester. Icon appears sometimes but disappears after a few seconds.
3.) Sometimes reached the screen where you can see the model name but stops there and goes to black with no backlight shortly afterwards.
Is this a logic board problem?

Got 3 of these and haven't experienced any of these anomalies, so I guess you have a hardware issue.

Hi all,
My TPT this morning for some weird reason stopped turning on. I plugged it into my dock. When it's in the off state it shows the charging logo. But when I go and turn it on, the screen stays black with no Lenovo bootup logo. The red dot in the back of the tablet however, is on when I switch it on. I initially thought that the power drained but I've been charging it for an hour and it still doesn't boot up. Any suggestions? Thanks
Press the tiny button next to the SD-card and then try and start the TPT. You might be in bootloader.
Otherwise, maybe your display cable became disconnected inside. Easy to do or fix if you've opened it up.

Tried resetting, no dice.
Also I don't think its a display problem. Since when its off and I plug it into my dock the charging logo does show up for 5 seconds. Also, when I turn it on, there's no vibrate that the TPT usually does. I noticed that the red light only stays on for maybe 10 seconds then goes dim again

Okay so this is definitely weird. I just plugged it into my PC and via USB and it actually started up! But when I unplug it from my PC it acts the same as before... battery indicates a full charge in android though...
this is a strange problem that i have not been able to see anywhere else.
ill start from the beginning
when plugged in the charging icon is displayed, after a while it fades out and the display goes dark and the tablet is unresponsive until unplugged and then plugged in and it happens again.
if i try to turn it on while the icon is visible it will turn on like normal but it will say 0% and the turn off.
using the fastboot mode to turn it off gave no result.
Hi, so my phone decided to stop working all of a sudden.
I was just doing things on my pc when I heard my phone rebooting, after I had recenly plugged it in.
It's running the latest stock ROM and not rooted. When I try switch it on it shows the Samsung Logo and on some occations some pixels create a fuzzy area underneath the logo text and at the bottom of the screen, it then switches off and after a while tries to boot again. When I try charge the phone it goes to the battery icon with the loading circle but nothing moves and yet again some of the pixles of the battery icon become distorted and then it switches off and tries again(also it vibrates twice before showing the battery icon). I can boot into Dowload mode and my PC recognises the phone(as well as odin) but I can't boot into recovery, or Safe Mode for that matter. I can remove the battery when in dowload mode and the phone remains on but I need the battery inserted to start up anything. I've only had my phone for two months now. Maybe I could be moisture from my shower earlier, I'll leave my phone in a bowl of rice overnight to see if that does anything.
Please try help me fix my problem. I've been looking for a solution all night.
Also due to me being overseas I can't format my phone as I'll lose my WhatsApp validation and all the pictures I've taken so far will be lost.
Thanks in advance.
It's not a software problem so you don't need to format.
My guess would be that you need a new battery.

The battery isn't even swollen though?
I just tried starting up the phone by turning it on, then plugging in the cable and hitting the battery out but it still didn't boot.
Unfortunately I'm far away from a big city so I can't get another battery to test it to be absolutely sure though.
Update:
I just tried booting it again and it got to the other Samsung screen where the LED is Blue and the Logo flashes blue behind it(Only got here once, hasn't gotten this far again yet). I left it for a bit but it just got stuck there and there was the same distorted pixels like in any other type of screen I get to also the logo stopped flashing when I tapped the screen and pressed the home button(this is when the distorted pictures started again).
Here is an attached Image of the flickering part of the screen. It gets stuck on this screen and flickers at the bottom and just underneath the Logo and eventually turns off.
No one know the problem?

It's a hardware failure. Let's hope it's your battery even though it's not swollen.

I tried a new battery today and it had exactly the same problems
So by some miracle it booted all the way to the lock screen and then rebooted from there right back to the lock screen again and I unlocked it and the home screen was fine and the phone seemed to function for a few seconds then it restarted and then got stuck at the Samsung logo again, I did manage to see that there was 17% Battery left so It has enough power to boot it. So I dunno what the hell could be causing it. It's such a weird problem I have no idea of how to fix it(within the warranty that is). I forgot to mention that the screen has 3 stress fracture cracks on the screen so somehow I think it is bending in my pocket, so that might be a reason why it's acting so weirdly.
I also noticed that if I leave the battery out for a decent amount of time and try boot the phone up it boots up for about 20 seconds and then reboots again into a bootloop again. Also the battery percentage is at 0% apon boot, by this stage I've plugged it into my PC to try pull files off of it(Which I managed to get some files off).
Hello
I left it charging all night long but when i wanted to power it on it shows the Google logo then it turns black with some scrambling white dots(noise) as i would guess is loading up.
I restarted it few times up to it was showing just a green screen .
If i power it on and holding the volume buttons it does show the bootloader menu (the green android) normally but when i choose recovery mode it starts again with the white noise .So basically i can only see clearly the Google logo and the bootloader menu.
I don't know what is broken so i can replace . The screen? The display ribbon?
I changed the battery 3 weeks ago and it has been fine up til now.
Oh and it does not boot up at all unless it's plugged in
Could a bad battery cause video issues?
Has anyone seen anything similar or can maybe give me a hint or what could be broken?
Thank you
try to flash stock rom again
maybe ur system and recovery partition gone bad.

So my S4 will show logo, and when loading recovery shows the tiny text entering recover mode (on logo screen) then goes dark.
On 'normal boot' just goes dark, when charging shows grey battery with lightning symbol for 5 seconds then goes dark.
It will not show battery a second time if you remove charge and replace.
Battery when removed (15 seconds or more) put in, phone immediatly vibrates then shows boot logo.
You need to have buttons (v up, pwr, home) held before putting battery in to get the recovery mode text to display. It does not display recovery mode screen.
My next try will be reboot recovery and blind guess 'clear cache'
Has any had this issue?
Phone started issue after a drop, I have examined circuit and did not see physical damage. (Not my first phone fix) I was originally thinking charge circuit failed but battery is fully charged (voltimeter).
