Do you have onboard video? Try that route for now until you get into Windows and install necessary drivers or whatnot. Unless you did something in the BIOS that messed with it.

So to summarise you had your machine plugged into your TV and it was fine. You reinstalled Windows and now although the system detects the TV, all you get is a blank screen?

What is your current display resolution?

Try a much lower resolution, something like 800 x 600 (or check your TV's manual for compatible resolutions). I can't say that this will change anything but it will eliminate the resolution as the problem.

If it works at 800 (or compatible resolution) then you'll know it was just your display settings
