Help Display issues galaxy tab 2

[memoryram]

Hi,
Since couple days i have some troubles with my tablet.

After few minutes my screen become dark and the colors seems to be red.

The pictures seems to freeze in background, you know even if i'm in the settings menu, my background, the samsung logo are freezed, that's like pictures under pictures.

I did a hard reset, but i still have the issues.

I would like to know if the lcd is broken or something else like the motherboard before to buy anything

Thanks
