Hello, while I am not as technically minded as most of you I'm no slouch and am at a loss to find a solution. Any advice you can offer would be greatly appreciated.

TV was clicking and not operating
I replaced the power board, sound but no image (start up sound normal)
Replaced the x-sus board, no improvement
Replaced the y-sus board, no improvement
Fully tested the y-buffer, no issues
Then I noticed the led on the logic board was only lighting up for 2 seconds and not flashing thereafter.
The power board is putting power to both sus boards but only for the time that the led on the logic board is lit.
My suspicion is that the power board was not tested by the supplier and has an issue

Many thanks in advance,

Kevin
