Tab 3 screen not doing anything!

[SeriousSeth13]

Hi,

I recently received a Tab 3 7 inch tablet off my brother in law (it was his for a year or so) and everything was going great with restoring it to factory settings until it came to trying to link it upto my gmail account. Halfway through it randomly restarted and since then nothing is coming up on the screen.
I know it is on because of the back lit screen and know that it's all there in its brain because it makes all the swooshy (official term) noises when you swipe to unlock.

Anyone who could possibly help will be a hero

Thanks in advance

Welcome to Android Central! Are you able to boot into Recovery? If so, try to wipe the cache partition: https://support.t-mobile.com/docs/DOC-16226

That's my main problem, I can't see anything that I'm doing on it as nothing is showing anything on the screen. Last night I think I managed to boot into download mode and stick TWRP on it using doing thinking that that might solve it (it didnt).

Whatever I do I have to do blindly through remembering what appears where on the screen.

I initially didn't think the screen was broken because I could see the back light working when the screen was black, but the more I faff about with it the more I think something must be dead hardware wise.

Although I do hope you tell me I'm wrong

The Tab 3 is MHL compatible, so you could consider getting an MHL adapter to hook the device up to your HDTV, where you could see what you're doing.

I suppose it's also possible that a connector came loose. Any recent drops or trauma?

 

[SeriousSeth13]

The bottom left of the tab does have a bit of a mark on it where it looks like it might have been dropped. Would this be relatively obvious thing to fix if I cracked (not literally) it open? I've already been in once to disconnect the battery.

I have popped it open and all the connectors were well attached. I even unplugged them and reinserted them and it's still the same. The black screen "lights" up but no more.

Is the 7 inch definitely MHL compatible? Reading around there is mixed opinions....

 

[B. Diddy]

Oh yes, you're right--it looks like the 7" version doesn't support MHL. I wish Samsung would be more consistent about these kinds of things.

Quick update, I haven't touched the tab since my last comment and I plugged it in today to charge, left it for a minute and it turned on for about 15 seconds then went blank again. Grrr!!!!
