I have installed an LCD in my vette... when I put it in I had the power board for the screen exposed. When in putting it in, with the power on no less, I touch it and smoked something.

I took it inside and replaced the main board with a new one I had from another monitor.

Now when the pc boots up or goes to stand by and come back on, it just goes blue screen and says "no signal"

Any ideas? Unplugging power from it and plugging it right back in it functions as normal.

TIA for any help.
