I have a HD TV with cable and a go video DVD/VHS player hooked up. I went to change the time and accidentally changed the setting on the DVD player from auto scan (I think) from off to on and now when I turn on the DVD player, my TV says no signal. The TV and the High Def box still work as they did in the past. HELP@!!

It sounds like you may have enabled the progressive scan output on your DVD-VHS combo. This is a correct setting if your TV support it. However most DVD players that support progressive scan will not support an interlaced signal and a progressive signal at the same time.

It would appear that you are using a composite type cable (3 RCA ends. 1 for video and 2 for audio) for this hook up. This means you have two choices.

#1 Look in the manual for the unit for the FACTORY Reset option. Its usually a combination of plugging the unit in while holding the power button or something similar to that. Without a model # I can't help any further with this option.

#2 Use a component video cable (3 RCA red/green/blue) to plug your DVD/VHS player into a compatible input on your HD TV. Your TV will pick up the progressive scan output from the unit and give you back your on screen display. At this point you can go back into the menu and disable progressive scan. And now just reverse the process to plug the DVD player back in using the composite cable.

It should be noted that if you have a progressive scan TV which HD TV's support you will get a better picture if you use the Component video cables instead of switching back to the composite cable. If you decide to use the component cables you will still need to run audio cables though.

Best of luck.
