Does the TV work with other inputs?

Select AV-1 or some thing in TV and plug DVD recorder Video-Audio output in AV-1 input of TV, playback any DVD and confirm its picture and sound in TV. Press Stop button of DVD recorder to stop playback.
Now plug Video-Audio output of VCR in DVD recorder input and select AV Input in DVD recorder, insert VHS tape in VCR and playback it and confirm you get VHS picture and sound in TV via DVD recorder.
Hookup between TV, DVD recorder and VCR is completed.
Playback VHS tape in VCR, Insert blank DVD disc in DVD recorder and press Record while you see VHS tape picture in TV.
Hope this info will help you.

tv will not power on. red light on switch blinks. power relay clicks, but no picture or sound.

Are you using AV connections(Red, Yellow, White) cable connections? If so The video connection may have come loose.

You might need a source picture from a camera or off the tv so that the DVD has some sync pulses to actually record the sound. Some won't do anything without any pictures.

My Direct TV has no sound or picture but does show channel info at the top. Any help is appreciated.

Some program have copy protection or your installations cable and setup try to set lower resolutions and make sure you see the picture on TV before record
Or tell me how are your installation from which device to where
I may able to help you
Cheers

When connecting VCR to TV. Verify all connections. First if the connection is with coaxial cable make sure you signal from outside is screwed to the cable input on VCR. Then the VCR/TV output has the cable running to TV input. If hooking up with RCA cables , which is the yellow, red, and white cables. Hook one side up to VCR output. Yellow for Video, while red/white to audio output matching the colors. The same is done to the Television input. yellow for video, red/white for audio. Do a test recording. Use a blank tape, not one already recorded on. Record about 5 minutes Stop recording , rewind and playback. You should see the difference.
