JVC HR-S9600U VHS VCR won't play/wind

[William Sommerwerck]

I bought this a few years ago to play a few tapes. I haven't used it in
about six years.

After it's set up (channels+time), it does everything //but// play or wind.
Other than loading/ejecting, the transport seems dead, dead, dead. (It
"knows" that a tape has been loaded, because -- prior to completing setup --
it automatically ejects a cassette missing its record-safety tab.)

ALL<< I want to know is... Is there a known issue with this (or related)
models that can be easily resolved? I have no desire to spend any

significant amount of time troubleshooting or fixing the unit. If it can't
be repaired in a straightforward manner, it will go into storage.

Please -- no tsimmes or megillah. Thank you.

Perished rubber belt somewhere, most likely on mode sw motor

 

[William Sommerwerck]

There are a couple of potential causes for this:

1) The heads are not spinning (motor problem or power supply)
2) The mode switch is not correct (may be dirty/corroded)
3) Belts are slipping

Without seeing the actual unit, it is difficult to determine the exact
problem. Given that this unit has been unused for a long time, I'd look at
the belts initially and clean the mode switrch. If you can do this, post
any progress made and perhaps we can provide additional guidance.


Those sound like simple, straightforward things to look at. Thanks.

Perished rubber belt somewhere, most likely on mode-
switch motor.

If I remember this model correcly, the mode switch is
activated by a tab that travels along the underside of one
of the cam gears. There is no "mode sw motor" involved here.
Be careful as it is easy to miss the alignment of this tab.

"Since we last spoke", I found that the capstan isn't turning. (The pinch
roller is tight against it, but the tape isn't moving.)

This is an almost-beltless transport (at least, as seen from the top). The
belt on the loading motor (?) seems to slip when it's time for the capstan
to start moving, but moves at other times.

Further thoughts?

I've got a rebadged JVC (Magnavox) that's old enough to vote.

Periodically, it needs both the mode switch and the leaf switch
that detects the cassette write protect knockout De-Oxed.

That is very likely due to the fact that it's stretched and slick.
That particular operation of the transport demands the highest torque
and therefore that's where it slips. You can try cleaning the slick
off with 99.0% isopropyl or triclor, (if you still have any).
Sometimes giving whatever the belt is slipping on a little push along
when it starts to slip will definitely confirm this diagnosis. Try to
find a new belt just slightly smaller, (but same thickness) than the
one presently on the machine to account for the increase in diameter.
PRB used to be a good supplier of belts. Don't know if they're still
around. Those were good machines. It would be a shame to let it go for
a relatively simple problem. Lenny

I cleaned it yesterday, but there was no apparent change.

I plan to search later today. If the belt is just a few bucks, why not give
it a shot?

I Googled PRB, but nothing appropriate came up.

Agreed.

[William Sommerwerck]

Belts should still be available.

They are. (It was used in dozens of JVC VCRs.) It appears to be an
LP30005-003A.

MCM Electronics carries belts, as one example.

This one doesn't show up. JVC sells it on Amazon, but the $5.50 shipping
cost is ridiculous. Encompass had it, too, but with an even higher shipping
cost.

If the capstan belt is slipping, that could account for the
problem.

It doesn't appear to be slipping. When I turn the capstan by hand, the
"idler gear" (that sends power to the hubs) moves away from the rewind hub.
(I'm assuming there's a belt connection.)

To reiterate, the loading belt does not appear to be moving when the point
is reached where the capstan should begin turning.

There are other problems like the power supply not
providing power to the capstan motor.

I'm willing to give the loading belt a shot first.

Where are you located? I have belts in stock
and can send you one in the mail.

Thank you! Please let me know the total cost.

I'm in Renton, WA. I'll send my address in a separate e-mail.

Periodically, it needs both the mode switch and the leaf switch
that detects the cassette write protect knockout De-Oxed.

The write-protect switch is working, because the unit auto-ejected a
cassette with the tab removed, while accepting one with its tab intact.

I don't know where the mode switch is, and I'm trying to postpone removing
the transport board.

The unit is a remarkable piece of "less is more", especially considering its
plethora of features, prominently splashed across the front panel.

Another source of belts, well sort of, are O rings. Several years
ago I picked up a large box of different size unused ones from a
transmission shop. Apparently many shops, when they do a "rebuild"
don't bother to rebuild anything more than they have to, and hence the
spare parts. They are all different thicknesses and lengths, and have
come in really handy.

Thanks for the suggestion. I'm afraid I don't know anyone in the auto-repair
business.

Another question...

I just tried to unseat the transport board (so I could examine its
"boughtum"). I removed the bracket behind the loading slot, then took out
the two large screws at the back of the board. I expected the board to lift
up and out -- but it didn't. (If this were a "junker", I'd rip into it. But
it isn't, and I won't.)

What am I missing?

PS: I was flabbergasted to see what this and other late-model JVC VHS VCRs
go for on eBay -- two and three times their original price. This is perhaps
not surprising, as the playback quality of this model is amazingly good (for
VHS). The TBC and other processing help quite a bit.

If the tape goes in properly but does not play due to non-spinning, how can it be fixed? This is what's been going on with my 2 vcr's. At first the tapes played, but then i tried to record and after a few seconds it stopped. Now it does not play it just says play but then nothing happens and a few seconds later it says stop.

Most likely you have a broken or streached belt in the VCR. I have not
looked but maybe you can get a belt kit off ebay or some other place.
I bought a belt kit for one of mine,but that was about 20 years ago.
Before the CD players and recorders came out.

I really don't want to throw a monkey wrench in, especially since I'm not
sure, but wasn't the HR-S9600U the flagship model here in north america?

Didn't it use direct drive for everything?

I had some goofy model brought over from japan that seemed to be the same
unit (or similar to the HRS10000U) with the addition of a built in satellite
receiver (worthless in the u.s.) but I'm sure it didn't use a single rubber
belt in it.

Maybe confusing it with a Toshiba or NEC I used to have but something is
bugging me that it was the JVC that did that on the upper end "editing
decks". A motor for everything, no belts.
