Hello,
I got today brand new pap k3 plus from aliexpress with jz4760 cpu. I started one game, played for 2 minutes, and console froze (textures mixed up with grinding sound in the background). I did reset and after that screen stopped working. Now every time when I turn on console I can hear the sound of menu but the screen is blank. Does anybody know how to fix this? 
Even if I plug it to TV its the same. Blank screen with menu sound like when you select games.
I ended up with two of these devices arriving today. One from Amazon (Slim statin on the box) on the other from the recommended AliExpress seller. Anyway I opened up the AliExpress one in other to make a backup of the micro sd. I did not realise how fragile the smaller ribbon connecting the screen to the PCB was. It tore and then the screen remained black but I could hear sound when pressing the buttons like the user above reported.
Luckily I had two but I would be very wary about opening the device up in future. I'm guessing somehow that very small ribbon cable tore somehow with the user above also.
