Hey guys so I have a 50" plasma (samsung hpn 5039).

It's been giving me hell for the last month or so. It turns on fine. Has no problem staying on but the picture is horrible.

It's dark, fuzzy/grainy and has what appears to be pink snow that takes up most of the top left portion of the screen.

I've replaced some of the caps that were bad but that didn't seem to change anything. I suspect that there are more bad caps so I plan to head to local parts store and grab some. I will include pictures.

Thanks guys

Not sure if this helps any but on the PS board the Va and VS pins are reading 101 and 86 respectively. Where as I've read elsewhere that they should be around 200/60ish?

Found voltage sticker. tested all voltages. They are as follows

V5d: sticker rated-5.3 actual- 5.3
VG: Sticker-15- actual - 15.3
VSCAN: Sticker-95 Actual- 110
VS: Sticker-82 Actual- 101
VSET: Sticker-125 Actual 144
VE: Sticker- 115 Actual 129
VA: sticker-76 Actual 87

Seems that they're all high.

I've noticed a few of the largest caps on the PS are bulged. But not bulged in the middle. They are bulged on all four sides of the x. The dead center of the caps is still fine. Not sure if that helps @ all.
