Screen black

Hi. One day my tablet went out. I checked and everything works except the screen. beeps are heard but the screen was black. if I connect the tablet to the TV with the MHL cable I can see the screen without problems. I changed the screen, thinking it was all I could affect. I do not know what part of the hardware must be failing. I've aiiilready changed the Flex cable and a screen ... and nada.alguien knows the solution? Thank you!!!

You could try yet another LCD just in case the one you bought was faulty.

Re: Screen black

I've already bought a screen thinking that mine did not work. I do not know if it's a software problem or hardware.

I tried (HARDWARE): Change the LCD. Change the LCD FLEX cable. Check connections.

I tried (SOFTWARE): Repair with PC Companion.

I get nothing. If I can see everything through the MHL cable. Sound works. When the tablet is working screen lights up but is black.

Please, can anyone help me?

Thank you!!!
