[cujo6984]

hi all

first off thanks in advance hopefully some one can help me

i have a vizio 42" sv420xvt with bad powersupply for what i believe to be a burnt up cap all that was left is the two wires in the board power supply is dps-284bp or 0500-0507-0560 it looked like a smallish 1/4 -5/16 diameter x 1/2 tall cap as soon is it was exposed it incinerated on the board there is a oval circle with (c815) no idea what to replace it with everything else looks fine

Not going to be easy - the other set worked on had another make of board.
Have you any details for D803 - a datasheet for that might have reference to typical usage. including the cap. A less close up pic of the bottom of the board might help
someone suggest a suitable one from the circuitry.

Would the Logic board have anything to do with thin vertical lines that have multiplied over time.

@CATOWLOO: No.
BTW, that cap is the snubber cap for diode D803.

The code on cap "C815" is 221 1KV. I believe it's a 220pf 1000v capacitor.
