Samsung PN51D530A3F – blinking red light & clicking.

[Yogesh]

I am working on this plasma tv and have diagnosed it to defective X-main board.
Q4202; Q4503; Q4101; Q4104 – SF10A400H are shorted
Q4302; Q4301 – RJP30H1 are shorted.
I cannot cross the driver ics – U4301; U4412; U4201. If someone chime their opinion or direct me to service manual, it would help a lot.

If you did your work and diagnostic was the x-main just replace it try not todo things out of the ordinary you might be burning the power or y-sus board.

If its a common fault, replacing a board will not ensure longevity. So I prefer fixing things to component level and use higher spec parts than the original.
