Re: JVC Model PD-42X776

The plastic top is bulging but the capacitor is most likely fine.
315V, 440uF.

Thanks Tom. I have removed from board and its leaking brown gunk from one leg and a crack by that leg.Also it was raised up from board and glue that was at base and board.

Re: JVC Model PD-42X776

If you press down on the top, does it depress?
If it does, the capacitor is fine.

Anyway, you haven't mentioned the symptoms of the fault. Bad caps there might cause a dim picture, excessive buzzing noise, or sparkling pixels. But I'll note that we've never seen the caps on sustain boards fail, apart from low voltage ones.

Tom no top wont press down and brown crud oozing from around one of the legs.Symptom is sparkling pixels. Have tried everywhere for cap but no luck.No one seems to have a 440uf cap at 315 or any higher. Any suggestion on locating would be appreciated

Re: JVC Model PD-42X776

470uF 315~350V would be an acceptable substitute.

That's great thanks! You wouldn't have a service manual for this set you can share would you.

Unfortunately not. However, it's a simple Samsung plasma panel, so it should be reasonably easy to set up. If you need help I can provide some.
