I recently got this 60" plasma tv for free. The problem is when you turn it on, it gives out what I believe is a hi voltage shorting/humming sound for several seconds,then goes back to the red idle light. I've traced the sound to one board, but that might not be it. I used to work as an electronics tech, so I feel comfortable working on it.
So far, this is what I've done.
Checked fuses, none-blown.
d/l the owners and service manuals.
The previous owner had this problem twice, he said that in both times, the shutoff would at first take a while, then get shorter & shorter until it was unusable. First time, a tech told him he replaced a cap, second time he gave the set to me.
PS, I know I can buy a newer set, I like to fix things, and love Plasma and CRT picture quality.
