Samsung plasma TV never stop clicking pn50a510p3

[hmendez86]

Have bit of trouble with this samsung plasma tv pn50a510p3. It only clicks one I plug the ac cord it starts doing that.....I check the y-sus and x-sus and there are perfect nothing wrong with x and y.....my thoughts are the main board or power supply......I disconnect the y and x and still the same I just leave the main board connected to power supply and doing same problem clicking non stop...when I plug the ac cable I see the little red light go on and off rapidly just one time and the clicking....this ligth is from the main board were the laser aux cable goes.....any suggestions.

It may be relate to bad c102 on the bottom side of the main board. Check out shop jimmy.com

You can solder 100uf 10 or 16V low ESR cap in parallel with c102 to see if the problem will go away.

Also check the Psu for cold solder joints, I did a similar supply the other day (donyang one like this not the Samsung one) and it had broken solder joints on the power fets.

When you get the kit, just replace just the cap only to see if it will fix the problem, I never have to replace the IC yet.
