I just bought a 10' VGA cable to connect my Dell Inspiration 1525 laptop to my 32" magnavox LCD TV. I had it working for a little while and all of a sudden the screen went blank on the PC source on the TV. It seems like either the TV or the PC is not recognizing the cable. I have no idea whats going on. If any one has any advice I would be grateful. Thanx for your time.
