Customer Question
I think I have...

I think I have the same problem that many have had. I have a Samsung PN59D530A3F Plasma TV. Turns on fine...great screen...warms up and then turns off and then back on with no picture. I have tested voltage on power supply and they look good while the screen works but then are real low after it goes off. With cables removed to Y sustain board, voltages are also low. I suspected heat being a problem. TV works great with a big fan blowing on back with back off. How do I isolate the problem from there?

Technician's Assistant: Are there any HDMI cables or A/V jacks (red, yellow, and white cables) plugged into your PN59D530A3F?

Yes, HDMI coming from cable box is feeding the signal.

Technician's Assistant: Was there a power outage recently?

I don't know. It actually quite working a while ago and I am just trying to figure out how to repair it. Without the fan cooling the back, it would turn off after 3 minutes or so. It ran fine with fan for 40 minutes, I turned the fan off and the TV picture went out after 3 minutes. It has now been running fine for 2 1/2 hours with the fan blowing on the back.

Technician's Assistant: Anything else you want the TV Expert to know before I connect you?

There are no visible swollen capacitors. No problems with lines on screen or any other issues other than an apparent heat problem.
