Thanks, Populas -
Would the tuner cause this problem even when using input from VGA or HDMI? I have tried using these two inputs as well as the tuner with the same results - the blue screen isn't actually the same type of blue screen displayed when there is no input, but has bands of color through it, accompanied by a very loud buzzing from the speakers. Very soon after, the screen goes completly black. The front panel power button stops working, and we have to use the power switch at the rear of the tv to completly kill power. After about 15 minutes, we can flip the power switch and use the front panel standby button to resume normal use for another 20 minutes or so before the cycle repeats.
I thought that maybe the power supply might have a bad capacitor? Maybe I could replace the supply? Found one online for $150, but don't want to spend good money after bad if it isn't the likely problem.
