I have a sony VCR that has been sitting around for a few years with a busted gear. As I was playing with my remote I noticed this section and would love to fix this VCR.

Without digging it up yet, my memory of the problem is one gear is busted. What information do I need in order to identify said gear and then order a replacement?

Thanks,

jb

First, I need the VCR model number. I have all the manuals and bulletins from being an authorized Sony servicer for 25 years. Then I need a general description of where it is located. (on the bottom, connected to a guide arm; in the lift mechanism; on the top by the pinch roller, etc)

Once I know the model number, I will have an idea of common breakage items also.

Most of the time, it is a lot cheaper to throw it away and buy a new one. Especially when the broken one is a few years old. They are a dime a dozen on ebay....

If this is one of the "H" series chassis (and you have no way of knowing that designation) then it is a basically indestructible machine with only about 3 failure modes. All common and repairable with cheap parts that were also redesigned to improve the original functions.

If it is a Sanyo or Funai chassis then repair is debatable.

One thing to remember is that all VCRs built after 2000 will respond to the CPRM flag and refuse to copy anything flagged as "Copy Never" (or "Copy Once" if the source is a TIVO or Cable Box) so a good VCR from the 1995 - 2000 era is worth keeping.

Parts are cheap, but repair labor @ $50/hr or so (or some ridiculous flat fee) is not!

Wow, I didn't expect so much activity on this thread. I loved that VCR. I kept it because I always figured I'd come back and fix it one day.

I'll grab a model number as soon as I un bury it from my workbench.

Thanks for the interest.

Yeah, but it sounds like the OP is planning to effect the repairs himself.

This was one of the first series of exchange models. They did not write a service manual and supplied no parts at all. The only parts available are from similar trashed units. The N50, 70, 90 had parts and manuals. The 51, 71, 91 were considered unrepairable. They were sold side-by-side for the same price. Surprised At least the Sanyo and Funai's had parts and manuals available.

If it works it's OK but most repairs will be impossible.

The gear in question on mine is the one that sits under the arm that pulls the tape over to the pinch roller. It drives the arm, and there is the problem: when I got it, the arm had stuck, and a few teeth were ground right off that gear, Oddly, the gear that drives that gear seems to be OK. If I could get a part #, hopefully I can get it for a decent price. It seems like a nice VCR, and too many of my old VCRs are failing. I have a nice Mitsubishi with a loading arm trouble. Looking at it, I'm not sure how it ever worked. Just doesn't look like it would work, under any load. And the SVHS capability seems to have failed.

I'll double check the manual (tomorrow), but I think this is the model that has the "RVS Arm" stick as the lube dries out. (the cast metal arm should be free to move) This is possibly the best VCR chassis ever built and is well worth fixing but some tech info is needed since the RVS arm has a critical adjustment associated with it. The parts are usually available cheaply from several sources.

A common problem with Mits VCRs was the pinch roller lift gear. The lube would dry out and the roller would not move up and down

The "RVS arm cam gear" (the one with the raised section that moves the metal arm and post) is # 3 736 143 01
The one that is just a plain gear "communication gear" is # 3 736 116 01
They are a buck or three each
