I have a similar problem when playing back recording in EP. It plays back briefly okay, then there is interference on the screen and noise as well, the briefly okay again, etc. It plays back perfectly when it records in SP. I have checked the same tape on another VCR, also a JVC, and it plays back fine, both EP and SP. I also have played back a tape recorded in EP on another VCR. The interference on the screen disappears and the sound is fine, but the picture is very jittery. Hope you have some suggestions to correct this.

The picture is unstable (vertical jitter) during play....we have the operating instructions and tried the instructions on page 31 of your booklet..but it doesn't seem to make a difference when doing the instructions. So how can I fix the problem so my granddaughter can watch her video's. Here are the steps I tried with no change. 1) Press the PLAY button. 2) Press the PAUSE/STILL button. 3) Press and hold the CH/TRACK DOWN OR UP button ( or CHANNEL on the front panel) to reduce the vertical jitter. But this did not help!

My problem is similar. When I record something it starts out fine, then about 20 minutes in I start hearing a faint intermittent hum or squeal coming from the unit itself. It happens during recording and when I play-back what I just recorded. While you watching the play-back, the picture distorts each time you hear the squeal. This has just started happening. I can play-back store bought videos and videos that I recorded some months ago just fine. I've tried different blank tapes and cleaning the heads. I'm beginning to think I may have to replace the heads.

Any suggestions,

Thanks

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.

Dear Joan, before I can help u, can you clarify a couple of points. Did you try your recorded cassetes in another VCR? Did the recording play properly on those? Is yours a Multi-System VCR? If yes, it is possible that you have set the input system to another system than the one you recieve? If you live in Europe, it is possible that you have set the VCR to NTSC recording? (Most of Europe is PAL. Or if you live in the North American continent, which uses the NTSC standard, you might have set the recording setting for PAL, and so are unable to view your recording. Another very common mistake people make is in setting Recording to LP or EP mode, and playing back the same tape in SP mode. Just check your VCR settings. If none of the above things are wrong, then try playing a Head Cleaning cassette. It is remotely possible that the Video Heads or Tracking /Contol Head is dirty. Pravin

SOURCE: Picture rolls on playback

Hi,

I beg to differ that the head is dirty. This is based on your post "...pre recorded tape is played the picture is fine..."

I am more inclined to suspect:

servo calibration. This would be the capstan motor controller. The recording speed slightly differs with the playback speed. You could try manually adjusting the tracking control and see if it corrects the problem;
recording speed selection, LP, SP, EP/SLP. try recording at the lowest speed LP;
video source, possibly of a different color system, PAL, SECAM, NTSC.

Hope this be of initial help/idea. Pls post back what is your video source, how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

I have the same jittery picture on playback on a Sony DCR-TRV460. I see you've stated that the drum could be misaligned/damaged. I've used the cleaning head with no success. I need to keep this device...

Yes sometimes when realigning the drum will not work. if the tapes were recorded with the drum out of alignment all tapes would have been recorded out of alignment. Delt with that situation where my player wouldnt play a customers tapes because his drum was out of alignment from factory. I had to use his camera to play all the tapes that were recorded on his camera.

Jittery video and sound, and now no playback

You may have damaged the heads if your cleaner tape was old and dryed out and had grit on it, buy a new camera head cleaning tape for a start, never rewind it as lots of folk do, if you do that all you do is put the old dirt back on the head.

How can I clean up a recording that is full of noise & static?

I Don't know of any Olympus proprietory program to remove noise but if you can export it to a .wav format, it can then be edited and cleaned up digitally buy any semi pro sound editing software.such as sony's Sound Forge or cubase? cakewalk. software used for edit old records for conversion to cd may also help here. From there you can then save to cd for playback. If sound editing is beyond you, contact a recording studio or media house that produces commercials, they may be able to help.
Hope this is helpful

Picture is jittery and voice is garbled with noise in background

Hello sneakymouse

It looks like you may have a servo or servo sync problem in either your recorder or your player. These are signs of such a problem. The circuitry that governs these function might be beginning to malfunction. Technically there is nothing that you can do in the way of repairing this unit you would have to have specialized equipment to trace down the source of the sync problem which is effecting your system. If you can not afford a repair shop right now I would suggest that you use your warranty and get it fixed. More than likely it is a problem with the servo IC or the sync oscillator circuitry.

I hope this helps,

Thank you,

Poor playback

Because the cable signal is OK, this eliminates the tuner as your problem and leaves the power supply which is a common problem. It is a switch mode type which often have trouble maintaining control of its output voltages and produce trouble downstream in the video circuitry. Either the power supply is failing which can be wholesale replaced for about a $150, or something somewhere else is failing and loading down the supply causing it to overwork. Usually in this case, you can hear a whine noise if you listen close.

Do you have a tracking control on the

Poor EP playback

hi sir
the speed in EP is differ from sp ,EP it is much slow then all quality would be less cause you are using less magnetic particles on the tape so here are many reasons for bad recording
first may be you have to clean video heads
or ,you have to clean the path of the tape in the recorder there are some metal guides that turnes with the tape to get it rounds the heads they may be dirty
or clean the capstain pinch roller and its metal roller that makes it run ( the capstain roller )
or you should have new heasd drum sir

A lot of background noise when playing back.

The pic looks like a TRC5880? If thats the case they are naturally quite noisey. The motors vibrate too much in my opinion. Theres not much you can do with it unfortunately. Suggest a new recorder or get that one repaired.
