Panasonic VCR pv-7451: No sound in "normal" mode

Hi, when I playback a casset tape in "normal" mode the VCR does not playback any sounds, but when I switch to HiFi mode it has sound. This is troublesome because I have lots of tape that's in normal mode only (no HiFi), and all of them I don't have sound. Is the VCR broken? Did I miss a connection or a button somewhere? I tried all the menus. Help! Thanks!

Re: Panasonic VCR pv-7451: No sound in "normal" mode

This is a wierd problem. First, You cannot do a manual selection for Mono / Stereo (HiFi) for recording in most Consumer Home VCRs. It is auto select, depending upon make, model, etc. Output of course can be selected - Mono, Stereo, HiFi, etc. Now, Most HiFi VCR machines have their Stereo / Hi Fi Audio heads on the Drum assembly, and the Normal /Mono audio Head on the Audio- Control Head. It is entirely possible that just the Audio - Control head has become 'dirty'. If you are good at these things, Unplug your VCR, Open the top cover, and, taking a cotton bud soaked in a few drops of iso-propyl alcohol (any Aftershave lotion will do) clean the Audio control Head. It is found as a small steel block on the mechanism, near the Capstan Pinch Roller ( a great big black roller). Wait for a couple of mins to allow the alcohol to evaporate, and then close the VCR. Power it up, and try playing the Pre-recorded Normal Tapes. Let me know if this has solved the problem.

You just have a dirty main video head. You can get a head cleaner tape or you can buy a tin of Servisol Video 40.
To clean with the Servisol, remove the top cover of the VCR. You will see a big shiny video head. Spray that head with the cleaner. You can also wipe it over with a cotton bud if it is very dirty. It's a good idea to clean all the surfaces that the video tape touches. If you don't know which, when you first take off the cover with the VCR on power, put a video tape in a press play then watch where the tape runs. Eject the tape, then clean with the spray and a cotton bud. You can even spray the cotton bud and then clean with that if you are not happy just spraying into the unit.
Make certain that the sprayed areas are dry before trying a video. It dries very quick anyway.

The sound on my Panasonic pv-4611 fades in and out while watching tapes. Doesn't matter whether they are factory or recorded ones by myself. Why?

This sounds like the Hi-Fi sound dropping out. It's mostly caused by dirt on the main video head. You need to clean it with either Servisol Video 40 or a head cleaning tape.

If pictures are rolling during normal playback, just check one thing first. Open the Cassette flap and see the condition of the tape. Is it chewed and stretched at the bottom? If yes, the problem is a worn Capstan / Pinch roller in the VCR. It is cheweing up the lower edge of the tape, and therefore the VCR is not able to process the 'Control Track.
All you need to do is replace the Capstan / Pinch roller.It is a big (approximately 1 inch high by 1/2 inch wide Black Rubber roller inside the VCR. REPLACE. Problem will be solved.

I don't recognize your first problem.  The "light to dark" issue I believe is intentionally engineered (mine does it too); it prevents recording DVDs on to tape.  Try running the DVD player directly to the TV.  Radio Shack used to have a box that would correct this issue too, you might check there.

Picture is jittery and voice is garbled with noise in background

I had the same problem recently with a Panasonic PV - V4521 which has worked for years for me. I tried everything including cleaning the heads with Q-Tips and pure alcohol. Nothing improved. I tried tape head cleaners. Nothing. So finally one day, as I was unscrewing the cables, this VCR fell down onto the bottom of my foot and drew blood. Now remember, I had been trying to fix this thing for at least 10 days.
So, I dragged it up and pounded the top of the VCR until the top caved in. Then, I opened my front door and tossed it so hard against the floor of my patio that pieces went flying everywhere. I gathered up the pieces and the twisted VCR, put it in a box, and tosses it real hard into the dumpster. It's fixed. I have no more problem with it.
