i have a panasonic th42pa20. it was produced in July, 2003. i had the shut down issue repaired in 12/03. About two weeks ago, my wife was using the tv and it shut down again. However, she got a two blink cycle. two blinks, pause, two blinks, and so on. anyway, by the time i got home, the tv was unplugged from its source. I plugged it back in and it has worked fine for the last 14 days with no problem. Anyone know what this is? The day it shut down was very hot and high humidity (I would say over 90 degrees and 90 percent humidity). My wife didn't have the ac on. Could this have been a problem with overheating? My concern now is that I may be making a problem worse by continuing to use the unit. Any help would be appreciated.
