Re: visio vx37l with black screen no sound

Ben,

I'd like to rule out the inverter if I can, before I get a main board.

Re: New Members - please post your introductions here

Hi folks, I'm a new member just trying to learn a little more about electronics and Hdtv's.

Now i'm putzing with a flat screen and living the dream in the South, playing lots of golf and tooling around in an 1965 Ac Cobra. Doesn't get much better then that.

I had no 24vdc, an found a tiny resistor blown. Their were also no visible bad caps or discolorations on it or any other board. So Being an impulsive guy,...
