Re: Sanyo DP42746

I have a Sanyo DP42746, I plug in the HDMI cable to the TV. Signal runs through. However when I unplug the HDMI and plug in cable there is no signal coming through the cable side. I need help. I don't want to end up paying 600-700 dollars worth of repairs since I am just a career and technical center student. After working on TV's for electronic repair I am stumped to a degree.

As I said,
HDMI > Signal
Cable > N/A
All other Jacks > Signal

If you can help, I would be grateful.
