Okay, here's a bit more in this mystery.... I disconnected everything
on the RCA projection TV model P61939 and shoved it off in the corner,
thinking about selling for parts. Sat for a week or so and when I
went to check it out and maybe break it down, just for chuckles I
plugged it in, hit the power button and WOW... it turned on and worked
perfectly!!!! HUH????? So I hung on to it and in rearranging the
house, I decided it might of been some overload that needed to
discharge and maybe it was okay now.

So it got put in a new spot and plugged in, worked fine, and figured
I'd set it up for video games when the kids visited. So there it sat
for a week, plugged in but not being turned on. Today I went out and
was thinking about hooking up a video game and get it set up for a
weekend visit, but when I hit the power button... NOTHING!!! Huh????
So it worked for years, then it didn't work at all. Then it sat idle
for a week and when it got plugged in, it worked again. Now it's been
plugged in for a week, tried to power it up, and nothing (again).

I did notice when I unplugged it and then plugged it back in, there
was a pretty decent power arc on the plug going in to the wall like it
was drawing power right from the plug being plugged in.

So does this narrow down what it could be? I'm at the point right now
when I'd kind of prefer to fix 'er up and set it up as a dedicated
video game display.

All thanks for suggestions and fixes.
