Open Question

I have a 1998 panasonic rx-ds790. The tape deck doesn't rewind or fast forward and the pinch rollers needs to be replaced. Heads may need re- aligning and demagnatied. Where in san jose ca (sunnyvale and the surrounding area) can I get it fixed?

The belts will have failed. You will need to replace them for the deck to be reliable. If you are mechanically minded I can talk you through it... You giving me a FixYa rating will help my profile and loosen my lips on how to overhaul your deck. :)

Hi saabangerman

The unit sounds like it has a take up clutch or takeup idler problem. Check all the drive assemblies in the unit. Remove the cover from the front of the transport inside the cassette well, and check the condition of the idlers and reel base drives. The counter belt can also gatherup and prevent the takeup reel from working correctly, or fire the auto stop mechanism preventing it from playing, although that sounds to be ok in this case as the unit will FF and REW ok. The takeup drive is supplied by a different drive idler as it requires much lower and more controlled torque. This unit was always considered to be a great tape deck and is well worth a bit of attention for restoration. You can get a new belt kit for $19.00 from here

I am more than happy to answer any other questions you may have about it, just give me a hoy :) Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Hi there. It will need a new pinch roller, and has a bias oscillator. problem. From memory, they use a module for the oscillator, and the pinch rollers are easy to get. Sorting out the bias may be the problematic part, and you will need to recalibrate the bias traps and controls if you want max performance from the unit once repaired. I would go about checking things like intermittent tape bias switch, and try wriggling the record play switch( internally) and see if you can get erase and rec back. Noisy intermittent switches can caused the symptoms you have.

If you are able to, I would be seeking a refund. If not, then repairs are feasible. Let me know where you are and I can help you find a repair guy. Cheers

Fast forward works but play and rewind stop after 3 seconds on a panasonic boombox


You need to investigate the method they use for auto shut off. There could be another belt in the unit or the reel table drive of the right side known as take-up is not being driven sufficiently.

I have a Sherwood DS1150 tape Deck. Problem Cant open Cassette Door, tape is inside . Will not rewind or fast forward. Wont play. Any advise


Very likely the tape is wound around the capstan.

You may have to get at it by taking the unit's case off.

If I am right you might have to destroy the cassette unless you are very careful. Or, at least, have to cut the tape so as to unwind it from the capstan.

You could also try to open the door just enough to lift it up and off ... as if you were going to clean the tape heads.

Will not reverse play on deck 2-just goes very fast on this


This condition, regardless of which way the tape is moving, is caused by the failure of a rubber pinch-roller to trap the tape between capstan and the passive roller.The speed is then caused by the part of the drive driven by a small belt and a clutch that should only keep a small amount of tension on the tape in ensure clean rewinding of the tape after it has passed the head.
Lubricant in part of the transport's moving parts or a dried-out rubber roller may be causing this.If you want to try to clean the pinch roller, don't use alcohol since this can further harden the robber.Use a clean fiber-free cloth or paper towel wetted with a LITTLE naphtha and turn the roller on the wetted area. If you get some dark smudging, the treatment is working.

The auto stop mechanism seems to have completely stopped working. When play a cassette, it eats it. When you put the deck into play mode without a cassette and push on the pinch roller with your finger, it...


When's the last time it was cleaned? It surely needs it now.

Never touch the any part of the transport that directly contacts the tape with bear fingers.

This sounds like a failure of the take-up (left) reel to take up slack as it's fed in by the capstan.

You can probably trust the machine to fast forward or rewind a tape to test the ability of the reels to manage slack since either action only requires one reel to pull while the other just coasts. Failure would look like stationary tape that eventually would time out and reset the command.

If it won't do fast transport motions that eliminates the capstan/pinch roller.

If it CAN FF and REW then the capstan, pinch roller, heads or something is probably glommed up with sticky tape oxide, which brings us back to the first question.

Re: Model PV-4523S


You can try cleaning it with a VCR tape cleaner to see if the pinch roller have build up on there. It could be that the motor isnt feeding the tape up against the recording heads properly and may need an adjustment. If you can take the top cover off, you should be to see what the problem is by the way the tape is being inserted into the machine.

Tascam 644 midistudio tape deck problem


Halo I have the same problem. The motor that moves the tone heads up only shake a bit but dont move it up to the tape.
The take up clutch motor does not move at all and there is no volt on the motor.
Did you find a solution?

Rewind or fast forward


Though not familiar with this model, VCRs of all sorts have an idler mechanism which drives the supply and takeup spindles. Either the idler is somehow defective and slipping, and, assuming this idler is belt driven, the belt may be slipping just enough to cause a no Rew/FFW condition. If you had access to a test tape jig (a clear dummy tape, which allows a tech to view what is happening in the area normally obscured by the loaded tape), this might give a clue as to what is happening. On alot of machines, a problem with Rew/FFW would also mean a tape takeup problem in standard play, result in tape spilling out inside the machine. Sensors would catch this condition and go into a error mode, as yours is doing. One other thing which might be happening here, is the pinch roller not being disengaged from the capstan in the Rew/FFW modes. I think this is where I'd look first, and you can probably see if such is happening just by pulling the cover off the VCR. The pinch roller is just to the right of the rotating video head. In the play and forward/rev search modes it will press the tape up against the capstan (a rotating shaft). When in Rew/FFW, the pinch roller should be pulled back from the capstan, maybe 1/4 inch or so. Whatever the case, repair will likely take someone tech savvy. Costs might not be economically justified, with the low-cost, disposable rigs sold in the last 10+ years.
