Noise bars playing VHS-C tapes with adapter on VCR (audio ok)

Hi there,

I'm playing VHS-C tapes with a JVC adapter C-P6U in two VCRs:
JVC HR-S5800E (SVHS VCR)
LG RC68223 (VHS VCR)

So far I haven't had any issues but last weekend, when i play any VHS-C tape on JVC VCR i get noise bars and the audio is ok.
I play the same VHS-C tapes on LG VCR without issues, so i presume the adapter is ok.
Regular VHS tapes are playing well in both VCRs, so i presume the video heads in JVC VCR are ok.

What could be happening ?
I already play around wih manual tracking in JVC VCR without success.
Unfortunately, I have some SVHS-C tapes that I can only play on JVC VCR.

Please help.

Thanks

Can you upload to the forum some video or still examples? Does the problem VHS-C come up as SP or LP on the VCR's front panel display? LP recordings use different heads to SP and tape-to -head alignment is more critical than on SP recordings. So if there is an alignment problem it's more likely to be on LP recordings.

Hi there and thsnk you for your help.

I only had the opportunity to return to this issue last weekend.

Over the last weekend I did some more accurate tests.

I think i have 2 different issues:

1) "LP recordings issue"
LG RC68223 (VHS VCR)
Plays well VHSC SP and LP recordings, but some LP recordings without noise and others have some intermitent noise.

SP recordings without noise.

2) "horizontal jailbars issue"
JVC HR-S5800E (SVHS VCR)
Plays well regular VHS SP and LP recordings without issues (LP not so well).
Have horizontal jailbars playing both VHSC SP and LP recordings; it seems the tape is playing at a diferent speed.

It even seems to me that this VCR dont have noise in the LP recordings that are appearing in the LG VCR (LP recordings issue).

obs.
always used the same adapter JVC C-P6U in the two VCRs
obs.
20 days ago, JVC VCR played well a VHSC LP recording tape and today i get the "horizontal jailbars issue".

What i can do ?

Please help.

Thanks

Hi again,

I cleaned it in the spot indicated in the image and no luck.

Meanwhile, i found a regular SVHS tape recorded in VHS LP mode, and sometimes it plays well, other times it gives an image like that of VHSC tapes !!!!
Did I clean it incorrectly, or is there a problem with the control audio/head?

Thank you.

The control head is right at the bottom; you should be able to see it if you look close.

Often times small variations in the tape tension can be helped by running the tape back and forth from start to end
once or twice.

Also open the flap in affected areas and look for tape damage

I've already gone back and forth several times with the VHSC tapes.
The problem occurs with all VHSC tapes in SP or LP mode i tried on the JVC VCR (near 20 tapes).

Now I'm surprised that the same problem is happening on a particular regular VHS LP tape, but intermittently.

Thanks

But all VHSC tapes are playing well (except some noise in some LP recordings) in LG VCR.

And the VHSC tapes i tried 20 days ago also played well in JVC VCR.

And i found a regular VHS (LP recording) tape with the some issue of the VHSC tapes playing in JVC VCR ?!?!?!

Thanks
