Question about RCA VR637HF VHS VCR

Poor recording at start of tape

We have an RCA VR637HF VHS VCR. It makes a groaning noise when it first starts recording and when we play it back, the first 3-5 minutes have a poor picture and barely any sound. We record everything we watch and we have had this VCR for about 2 years so I wonder if there is a part that has worn out that I could replace to fix it. I appreciate your info.

Re: Poor recording at start of tape

Hello. This kind of sounds like the loading deck is a few teeth out of time. In other words the tape is not fully dropping down. When the drives start pulling at it the first few minutes of playing it probably seats down a little further and a little further until it finally bottoms out and seats correctly. This I have seen before. The timing issue can result from pushing a tape in a little hard at times instead of letting the loader pull it in itself after it makes its first switch. At some point the loading deck went out a tooth or two and has remained that way ever since. Putting one of these loading decks back in "time" provided there is not any damage to the loading gears should be handled by someone experienced with this. If your familiar with gearing it would simply be a matter of marking the gears when you "trick it" to load a tape. The metal tape retainer should hit bottom when it drops in. When you start your re-timing process you only go one tooth at a time until you finally get it to hit bottom. You should not go a tooth more because you may cause damage to the main gear or one of the others. Good-luck and hope this helps.

The heads just need cleaning. I recomend Servisol Video 40 to do the job best and taking off the top cover for a good clean with it and some cotton buds on all surfaces where the tape touches.

Blank VHS tapes work; Movie VHS tapes don't

Hello statman_4

I have an important question; Are you watching a VHS tape you recorded of another VHS movie? In other words did You rent Ben Hur and record it and then tried to watch the recording? If you did that's your problem. VCRs in the late 1990's (1997-1999) began to employ MacroVision circuitry in all VCRs, and DTR. MacroVision Circuitry makes the VCR record tapes with MacroVision in such a way that the horizontal and vertical sync pulses are not at the proper amplitude, and the AGC (Automatic Gain Control) is tricked into over compensating thus creating the scrambled picture. There is a way around this. You need to buy a video stabilizer SIMA makes such devices and some other companies do to. You feed the signal from your VCR into the unit and it corrects the video image by readjusting the video signal.

I hope this helps,

Thank you,

VHS Tape on Sanyo Doesn't play on other VCR's

the heads on the sanyo vcr may slightly be out of alignment from years of use.when playing a recorded tape from this vcr to another, the other vcr's alignment maybe right on track thus causing the poor can possibly try cleaning the heads with a head cleaner or a high grade blank tape,but i don't think this will solve the problem. but you can try.
good luck
p.s also try higher quality tapes to record on.

VCR says safe

Hello. Have you tried unplugging the power from the VCR for more than 24hrs? This may resolve the "safe-mode" feature going back to "default" and permit regular use after this amount of time elapses. That is kind of unusual for the stepping upon the remote to cause this?

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

Tapes not playing

Hey do the tapes play at all? sometimes some tapes recorded
on other machines won't play on others. maybe you need to adjust the tracking on the VCR you are playing it on. If the tape
was recorded on a VCR that is misaligned it might not play back
on another VCR. Also the tape may have been recorded on a
super VHS VCR in et (extended definition) mode if so they won't play on just any VCR. If the picture looks scrambled like a
premium channel on analog cable then it's probably recorded in et.
and if its recorded on super VHS tape it may eject out of your VCR.
They don't make these S-VHS vcrs anymore but people still
have them around. There is also Digital VHS they're not
compatible with VHS either. A VHS recorded in et mode will
play on some more expensive vcrs it should say so on the box
or instructions.
