Older VHS tapes play 'sped up' on S-VHS

Older tapes (not ancient, but taped on our prior machine) seem to play at a high speed when inserted and set to play - why is this?

Re: Older VHS tapes play 'sped up' on S-VHS

A couple of possibilities: 1. One of the machines had a audio & tracking head alignment problem. If memory serves, tracking pulses are recorded on the bottom edge of the tape, and if one machine's head is slightly off, then these pulses aren't being picked up.

2. Do both machines have 3 play/record speeds? Many machines had SP, EP, & LP. Some didn't have EP, and if your older tapes were recorded in EP, perhaps this would cause your problem.

Both of these possibilities might be way out in left field.

Perhaps you could have a friend try your old tapes in their machine- in short, narrow down the defect. Is it the older VCR and it's recordings, or is it some goofy problem on the new one.

Lastly, you might check the audio/tracking head- see if it needs cleaning. This head is just to the right of the rotating video drum assembly.

VHS tape is running at high speed when insert it to VCR. no playback..buttons doesnot work.

Check if the fast forward button is more inside than the rest of the buttons. May be its stuck in the ff position. After all they were just micro switches below the plastic buttons strip. The specific ff micro switch may be stuck, if I were you I would try some switch cleaning spray to loosen it. But be prepared that the control ic is busted.

Hi On my Pansonic DMR-EZ49V, I get distortion along the bottom of the screen when playing back vhs tapes that have been recorded on an older machine, I have adjusted the tracking but it has made no...

This is a real bad problem to solve. Unless your new video has been set up badly, there's little you can do. You see it's like this either your old machine was set up badly or your new one was! To get your new one to play back the old ones would require the aligniment to be reset to the old machine settings. However when you put a new machine previous recording in - that would now badly track. A new recording (made after the adjustment) played back would be ok though.
The only way you can tell if the new machine is set up right is by putting in a commercial film video tape. If that tracks badly it has been set up wrong.
I can say this however Panasonic VCR's have a reputation of being set up well and good at tracking videos. So if it can't track the old video tape it might be well out of alignment, especially if it is not a Pansonic model.
If the old machine is still working, it would be best to play it back and re-record with the new machine.
Otherwise you would have to carry out an alignment - play back the tape and re-align back to the correct setting.

I have a Sony SLV-EZ717

It sounds like the taped program was recorded on a different speed. The other VCR that you are playing the taped program may not have the speed needed to play it correctly.
Next time when you record a program try to make sure you use a speed that will be compatible on both VCRs.
For example a tape that last 120 minutes, using the different speeds will give the following recording times.
SP means "Standard Play" >>>> 2 hours
LP means " Long Play" >>>>> 4 hours
ELP means " Extra Long Play" 8 hours

Older VCRs have all the 3 speeds but newer ones only have SP and ELP.
Hope this helps.

VHS tape was playing . After stoping does not play. Other tape will play

The idler wheel (that only drives the tape in play or scan modes) is slipping too much (very common problem). Try verify this by putting the tape in play then immediately press the fast fwd or rewind buttons to scan the tape. On older machines, the idlers used rubber friction tires - on newer ones, a clutch. Either replace the tire or increase the spring tension on the clutch.
Hope Ya Fix It.

My VCR is playing too fast

try recording on a blank tape and setting the tape speed to SP (standard play). you should also see options for (LP-long play) and SLP (super long play). I think your machine is stuck on SLP option. if no-go, look for a manual on the web.

VCR functions do not work (play, record, ...)

Sounds like the idler assembly isnt working. Without this assembly, the system cannot get the tape to actually move, and most systems will shut down if the tape isnt moving to prevent damage to the tape. In truth, this can be a complicatred repair, requiring the machine to be taken apart quite a bit. I would suggest taking this kind of a problem to a repair shop, but with the cost of simple VCR's coming down constantly, and the upcoming switch to DTV making the machines tuner obsolete, it would probably be more economical to just replace the machine.
