Hello! I have the following problem:
My tv doesn't turn on. At first the screen was flickering and on the next day it didn't turn on at all. I've bought a new power supply and change it but no effect. The strange think is that when i umplug the cable that goes to the mainboard the screen lights up as you can see in the pictures. And when i plug it back in to the socket it goes off and that's it. Can this be fixed somehow or nothing can be done?
