LG 50pn6500 no video

[jdoncouse]

Checked the power supply voltage and it looks good. Backlight comes on. None of the buttons works though and the logic board blinks like 1, 2, long 3, 4. I know the main boards have a habit of going out and i was just seeing that it sounded like the problem and if there is a good place to find one or a possible subsitute. thanks

This is a plasma.

Running test patterns on the logic board would confirm bad main board.

if you run the test pattern and no picture is displayed, what does that indicate?

A fault somewhere else... Any board can cause no picture in a plasma.

Looks like Logic Bd failure, to me.

If the buttons don't work, then it rather indicates main board failure. What do you mean by "Backlight comes on"? Is there a sound?
