JVC HM-DH3000U D-VHS VCR has unstable audio on analog inputs?
 

Hey guys, just got back my JVC HM DH30000U back from Jots, and though it powers on now, it has a set of new problems. Let me just start off by saying that I didn't have ANY of these problems before sending the deck into Jots for a dead psu repair. The machine will playback and record VHS/SVHS tapes fine. The problem is when trying to record/playback DVHS tapes. I tried the last recording made on the machine, and though the image was fine, the audio would not output through the analog L & R. I heard breaks in the audio, and at times it was intermittent, but it would go away and be left with no audio. The only way that I got the audio to work was through the firewire port inputed into my DT100U. Next, I decided to try to record on the machine from the IEE1394. First off, I hooked up my DT100U to the front firewire input, and it wouldn't recognize it at all. However, I did get it to recognize it from the firewire input on the back of the unit. Next, I recorded the video signal, and when I went to play it back, I got "Wait a Minutes Calibrating... [201]. What could be wrong with the unit?

Also wanted to add that when using an analog source for input, Nintendo 64 with Super Mario 64, via S Video and analog L & R, I inserted a DVHS tape into the unit, and when it recognized it was a DVHS tape, the audio went out. When I either ejected the tape, or if I set it to SVHS mode, the audio came back. What does this mean?

Clumsy handling by return shipping (UPS?) could have damaged the internal audio connections.

The DV issue may be unrelated. My question is this: Had you successfully used this feature in the past?

Also recall that video game consoles tend to output non-standard -- yet "good enough" for a TV set -- type of signal. So testing analog input is best done with other known-stable devices: another VCR, a video camera, etc.
