JVC HR S6900U Loading and Ejecting problems
I bought a JVC HR S6900U from ebay about 2 years ago, and its worked fine up until now. A few months ago, when I tried to load a tape, the loading motor would make a faint sound, and then the unit would eject. The only way that I can get a tape into the machine is by hand. When I get the tape into the machine manually, it isn't seat properly, so it tries to eject. Unfortunately, eject mechanism sounds, but it won't eject the tape at all unless I manually move the cassette housing by hand. I have the service manual for the machine and I've gone through everything, but I can't seem to find out how to fix this problem.
Everything else works on this machine, the record and playback work perfectly, its just that I can only manually load and eject the tape by hand. Does anyone have any advice on how to fix this? I've been thinking about sending it into JVC for repair but I'd hate to have them overcharge me. And no, I don't wanna throw out this machine, as I think that this a great machine, even better than some of the DVHS machines for playing back VHS and Super VHS tapes. |
Does the eject motor seem to work? Or could it just be a worn out eject motor?
I have a bunch lying around... if you think you need a new one, let me know the part number and I'll see if I might have one. |
I have a similar issue with a JVC SR-V10U, where the transport is malfunctioning. As much as I know about S-VHS VCRs, JVC brands in particular, I can't seem to locate an obvious problem. I can only assume that the motor may be blown on it. For that reason, I'm taking it in to a trusted repair service next time I take a road trip. (I'd mail it, if I didn't already have a trip scheduled in that general direction within the next few months.)
These guys have proven themselves to us: http://www.jotselectronics.com/ Yeah, their website looks like it was designed in 1995, but don't let that fool you. Their fees are far more reasonable than JVC, and their techs more competent. ($30 diag, for example. Or re-alignments $75) As with your 6900, the V10 won't seat properly with manual insertion. The transport has several gears and levers that are supposed to work in unison, and that just doesn't happen when you manually insert and pull/turn the obvious knobs and gears. No, DO NOT THROW THE MACHINE OUT -- that would be a bad choice. :eek: Let Jots fix it. Even if a repair ran $100-150 (including shipping both ways, etc) -- it's a bargain. You can never replace that VCR. Fix it. Or sell it in our Marketplace forum (free, no fees). Definitely don't throw it out. |
Alright here's what happens when I try to insert a tape into the unit. I push the tape into the machine, and the motor makes a faint whining noise. After that, the unit shuts down. The only way I can get the tape into the machine is by manually pushing it in. Then, I have to manually move the gear on the cassette housing that loads the tape. Once I do that, all functions work properly. When I press the eject button on the VCR, the tape goes back into the cassette as it should, and the VCR makes a noise like its trying to eject, but it doesn't eject. The only way I can get it out is by moving the gear that loads and unloads the tape from the machine. I've checked the belts on the cassette housing and they look fine to me. Could it be a broken belt underneath the machine?
Also, at one time I had tried a cassette housing from a parts 6900, but it still wouldn't work. Can anyone diagnosis this problem for me? |
I had this happen --TWICE NOW! (ugh!) -- when a deck was zapped by a major power outage. I lost two of my favorite VHS VCRs this way. One wasn't on a battery (my own dumb mistake), while the other one was. The surge was so strong it blew out the UPS battery and the VCR turned off with a loud and audible "pop" sound.
The electronics were fried. Now, on a JVC unit, I had a similar issue. For that deck, I simply cleaned it. There was tiny dust and debris in the track of various moving parts, and it would cause the unit to seize up. I did completely dismantle the unit, over a period of several days. Not fun. |
Just would like to let everyone know that I have the service manual and I took it apart to see the mechanism and then the machine would no longs er turn on. I suspect that a fuse could have blown in the power supply. I still want to get this machine repaired, as I don't want to hunt down another model of this machine on ebay so I sent an email to Jots Electronics just a few minutes ago so I'm waiting to hear back from them.
I think this is pretty cool so I'd figure I'd share this with everyone. For this machine, I virtually have the original box, except it says 4900U instead of 6900U on it, all of the original packing materials, and all of the original accessories mint in box. This machine itself even has the original factory sticker on it!!! So I'm definately going to get this machine working no matter what. |
Is there a fuse? If so, dismantle the power supply, and remove it. As a warning, it may be as fun as mowing the year -- with a razor blade. Removing the fuse from an AG-1980P is an exercise in patience and aggravation. When I last did that, I was tempted to throw the VCR against a wall at least 1-2 times during the ordeal. It was not made to be a user-serviceable part on the 1980, so it was not put into any kind of convenient location to replace effortlessly.
You also need to match the exact fuse, which may require importing one from Japan. Don't use an American fuse that is "good enough" or otherwise close to the rating. Ignore anything told to you by an electronics professional -- it's not true. Get the exact, identical fuse, or you'll have other power-related symptoms pop up after the repair. For example, on-screen noise in the video signal. |
Lordsmurf, the machine in question here is a JVC HR S6900U, one of the Super VHS VCRs that is prefered for dubbing. What happened was that I had taken the machine apart to try to find out why the machine wouldn't load and unload tapes and then all of a sudden, the machine just died on me. The machine wouldn't come on at all. I believe it is still a valuable machine to fix, as the picture quality is greater than that of the later JVC SVHS VCRs. In addition to that, I even have the semi original box with all of the original packing materials plus accessories. To answer your question, there is a fuse that is located inside the power supply of the unit. I'd prefer not to mess with the machine anymore, as I don't want to make the repair cost higher than it already is. I guess I will check the service manual to see if the part number for the fuse is listed there. Thank you for your input though!!!!

Thanks very much for showing me that. However, I have seen that auction up many times before. I am also the guy who bought the 6900U that was on ebay in February for $99.00 on ebay that came with everything mint in box. The only problem with it was that the machine had the dreaded white streak problem, so every tape that I had put into the machine for playback had white comets shooting across the screen. Supposedly this guy had a 100% feedback as well. Also, on that one machine, the rewind motor out of play mode is really squeaky so I guess the machine needs to be lubricated, have some belts replaced.
The one other thing that is unique about this unit is that it is one of the first 6900U's ever produced, as the manual was printed in June '93 and the loading motor of the machine says the unit was produced on June 22, 1993. The other thing thats different about this machine is the rosewood side panels. On the first models, the holes for the screws were longer, so they had to use longer screws, as supposed to the machines that were produced in late 1993/1994. So I'm keeping my hands crossed to see if Jots can quote me a good price on this machine. Just out of curiousity, do you think I could get this thing working even though the power died on the unit? |

Alright everyone I have some news. Jots electronics wrote back and said this to me:

I've used Jots since the 1980s. Was a walk-in customer for many years. They'd fix everything from Nintendo systems to camcorders to VCRs. Yes, I trust them -- more than I would trust JVC support for a VCR. (MAC warranty support is worse yet.) Those fees are reasonable, and haven't changed much in 10 years. Very good price.

Good stuff. :thumb:
Sadly some of it is lost in translation. When I get some time, I want to come back to this post and clean up what's written here for a more accurate English language version. Neither Google nor Yahoo/Babelfish do it justice. Quote:
