I ask because you mentioned in your old thread that you were testing with a flatpannel set and no signal to the VCR tuner....Some flat panels are finicky and won't show a picture unless the signal they get is near perfect.

If audio and video are dead even thru the tuner you will need to get a service manual and a oscilloscope to troubleshoot it....Or get an ESR meter and some new caps and HOPE it is a bad cap and that you manage to find and replace it.

If only the tape video is dead the tape heads are either dirty or bad, or the signal chain has a problem.

I double checked it with an older CRT Television and it seems that the Tuner is working fine its just the VCR Part when playing a tape doesn't work right, all I get is a a blank black screen, and no audio either. So I'm not sure what's going on with it, the VCR Doesn't put out any video or audio when playing a tape in either the RF (channel 3 or 4) or the A/V outputs so somethings wonky about the video and audio signal going from the video and audio heads of the VCR to the output signal area.
