I have a tablet which belong to my friend, and have some question:
1. When it power on and use a little while, the screen start to flickering (shown picture below).
2. The tablet connect through HDMI to TV, on TV the display is fine and touch function is normal.
I suspect this problem is from the screen, so I disassemble it, disconnect the screen cable, and restart, still flickering. Don't know where happen...
Is this main board failure or LCD board? I have to decide which part should I buy... Thanks!
