Pioneer Plasma Only Works When Warm...

Hi everyone, I have a Pioneer PDP-5030HD system (PDP-503PU & PDP-R03U) It has worked fine for years. Purchased in 2002. Has about 1050 hours total. Moved tv to new location and about a week later would only stay on for about 1 to 1 1/2 minutes then will go shutdown back to standby. I figured out, i think, that if I start the tv up in service mode and leave it there for about 5 - 10 minutes to warm up (30C+) it will work fine So here's what I have done three times. I turn the set on in service mode. Wait until the sensor temp reaches about 30C and then turn it off and right back on regularly. All three times it will stay on in standard mode and the last time I ran it for 3+ hours with no problems. Let it cool down all the way, 5 hours, and turned it back on and it has the same problem, shuts off after 1 minute. A service shop quoted me for the power supply but wouldn't the tv not work at all or not stay on at all? I assume if the power supply was bad it wouldn't turn on in service mode with no problems. Am I wrong? I can't see if it will stay on in service mode for too long because I don't want the top service line to burn. Sensor temp gets up to and no higher than 61C. Too high? I read 75C or 77C is the danger point. Can anyone help me try and diagnose this over the net? I have searched for two nights now and can't find any similar problem through Google searches. Thanks in advance for taking the time to read.
