Hi, Ray
These are the values your looking for :

C502- 1500uf  10v
C703- 680uf  16v
C408- 100uf  50v
C405- 100uf  50v
C602- 100uf  50v
C600- 1000uf  35v
C601- 1000uf  35v
C403- 680uf  35v
C410- 220uf  50v
C700- 1000uf  16v
C500- 3900uf  16v

I too have  the same Clarity 42" tv. I  changed C602,C405 and C408,all of which had domed tops.
Reseated the power supply and the Clarity logo would flash on screen for a brief second then the screen would go black,even though the blue power light stayed on.
I'm going to replace all these capacitors to see if this fixes the problem.



Hope this helps

Regards


Patrick

Hi Ray,

Great that you managed to repair this board.

I have just not got round to replacing the capacitorson on my board yet...

Was hoping to just replace the whole board with one from Ebay...

Seems these boards are as rare as hens teeth.

Regards
