Have a HP Pavilion sxxxx series computer hooked to my tv. Been doing well for 7 months now. Today I get home... start watching some bones and the tv suddenly says "no signal" then bounces back to the video. Did it several times. The 'sleep' on the tv is off. I was using the computer once when this has happened tonight so it's not a 'sleep' setting. I took the video card out and resat. Still happened. Think I burned up the video card? It's setup DVI-HDMI.
