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

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 prob= lem. 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.

Perished rubber belt somewhere, most likely on mode sw motor

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

Thanks. Appreciated.

If I remember this model correcly, the mode switch is activated by a tab that travels along the underside of one of hte 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.

Belts should still be available. I can look up the size later (I don't hav= e the reference with me at the moment.) MCM Electronics carries belts as o= ne example. If the capstan belt is slipping, that could account for the pr= oblem. It may be the belt, or there are other problems like the power supp= ly not providing power to the capstan motor. =20

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

Now I know what PRB is!

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

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.

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.

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

Thank you! Please let me know the total cost.

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

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. Lenny

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 ta pes 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 s econds 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.

Agree. A bad reel belt (run from the capstan motor) is the most likely.
