TV turns on, no picture, but has sound.
It turns on and off every 10 seconds most of the time. If it does stay on, it does have sound. The leds do turn on. I do not get a faint picture when I shine a flashlight . When I unplug the main board connection with the power supply, there is no standby light and does not turn on. All the cables and boards seems fine on based on visual inspection.
I replaced the T-con board and the same problems occur.
I did try to check the voltage on the main board, three of the pins were supposed to be 12V and I got 17V.
The is a piece of I think melted plastic on the power supply board, in the middle of the attached picture (don't know if that means anything).
Do you think the issue is with the power supply board, main board, or something else?
