Question about Samsung HPN5039 50 in. Plasma HDTV
My Samsung HPN5039 worked without problems over 4 years. Then the plasma was on and we left it alone for about an hour. When we came back it was black. No picture, no message, nothing. We checked power. OK. You can still change the LED status from OFF to ON and back with the remote control but the plasma is still black, like it's turned off. No one had access to the plasma and we checked everything that could cause the problem. On Samsung webpage we learnt it could be power supply failure or screen circuitry failure. What's your advice, gentlemen? Is it an easy fix or should we start to look for something new? Thank you so much for your time and we'll be looking forward hearing from you! Vladi
The plasma also never showed any sign of deterioration or possible problems.
Man, I love the internet! My seven year old HPN5039 finally died last week, and I could tell from the lack of high-pitched whine that the high voltage power supply had failed. Found this thread and ordered some new caps from DigiKey. Put 'em in this morning and the unit is working like a champ again. Thanks, guys, for sharing this knowledge!!!

I can confirm Vladislav/ Jaime867's repair... Had the same problem on mine. Replaced the same two capacitors and bingo back in action.
I think the issue is that the capactitors sit between two heat sinks and if the display is flush mounted to the wall there is poor ventilation in there. I'm going to get a better mount and hopefully this doesn't happen again.
Cheers and thanks for the great fix!!! Only $4 bucks!

Have the same problem, the same model HPN5039.
Found Screen power supply voltage falure on VS, VSINC and VSS.
Do not have schematics to troubleshoot further.
If I find schematics would be able to locate the problem and fix.
