Dual tape deck inoperable

Haven't used the deck for a while. Went to use it, both sides do the same thing. Everything seem to engage but the tape will not move and the systems attempts to auto reverse every few seconds. Any ideas?

    I am not sure of the proper way to respond to a suggestion but want to thank those who have made one. I still have the same problem. Head and other parts that normally require cleaning have been. I took cover off and all belts look to be where they should be. This is a Pioneer CT-401W by the way. Both sides do the same thing. Any more help would be appreciated. Thanks.

Clean the rubber pinch rollers with an alcohol swab. the tape is not getting required "grab" on these rollers and not pulling tape. the auto reverse is an attempt to rewind the tape because of confusion with no tape movement.

    hello, anybody there?

  • Marty marty Nov 18, 2007

    The capstans' (the rubber pinch rollers) drive belts are therefore stretched (from sitting too long) beyond their working circumference. They must be replaced. It can be done by you. Just take notes during disassembly. Finding the belts may be difficult. There should be a "vote" button for you...I don't see one at this end. Please vote at least "almost there".
    Thank you.

How do I get this device to play and record again? I often clean the heads.

if one reuses the tape often, ive found that the tape stretches and no longer covers the entire record path (or play path) , i still have a few cassette and reel to reel decks that I still use , and since the tapes are hard to find now I keep reusing the tapes more and more 4 the same thing , I guess its been like in the past year ive seen this tape stretching thing happen now

My technics cassette deck tr575 everything seems to work all the functions all the buttons but when I put a cassette tape in the unit I see no responce on the db meter... Everything is functioning on

There are 2 long switches, maybe 4" long, called record/play switches. These can certainly cause this. Try cleaning them with the power unplugged. You would turn the cassette deck on end, so the switches are vertical. Use LPS-1 or LPS-2, and spray a very small amount in the end. Work the switch back and forth and see if that helps. Good luck.

"A" side/deck wont play----"B" deck works just fine

Loose belts and lack of lubrication. Dual cassette decks are built to minimum standards so that it does not take much to push them over the edge to be non-functional. It is almost like they should provide a tape deck repair course with these types of units as it is most certain that you are going to need it. They want you to throw it away and buy another one. This is where the throw away economy started.

I have a kx-w4050 dual kenwood tape deck niether side will play hear click and counter moves one then another click. Is there a way to fix this?

Yes, the belts need to be check and idlers or whatever drive mechanism that is used in that system. Dual deck units are among the most unreliable units there are and a reason I tell people for the last 30 years not to buy those things. Almost most of the time they are not worth fixing due to their poor performance at the end. These are facts not just opinion.

Stuck head unit-- need help understanding the mechanics of a tape deck.

The solution to the problem comes from recognizing the type of transport the unit uses. This can be discovered by looking at the working side or by a person who has some experience working on these. Chances are there is a stuck flywheel assist mechanism and just because the belts are no broken or not turned to goo, that does not mean they are good. Also does the capstan motor turn? If it does not, there is no way the mechanism can right itself and that might mean a new capstan motor. Dual cassette decks were built for profit not for a long lasting unit- that is why the thrift shops should be full of them and why most of them will not work.

I have a TEAC W-450R Stereo Double Reverse Cassette Deck. For some reason, the REC/PLAY II side will not operate. It has not for some time. In fact, that is why I believe I mothballed it some years ago....

I have not seen those to a large extent due to their value not being worth a repair. I did work on them at Teac though. The capstan motor of the right side deck sound like it is burned out. I have some motors here so it is just a matter of if you want me to work on it or not. I get a lot of units in all the time- I am Skywave Tape Deck Repair in Chicago area.

Wheels on the tape deck don't turn on either side, forward or reverse on Sony dual cassette tape deck

You have a broken transfer belt and it needs replacement.
This will require you to take the tape deck apart to service it.

Kenwood KX-W6080 dual stereo cassette tape deck

I have the same unit which had the same problem. It has to do with dirty contacts on each tape mechanism.

Remove the main cover and look down on each tape mechanism. You will see 4 contacts on each unit. These come in contact with the tape. Remove each unit by removing 4 holding screws.

You will now be able to spray some contact cleaner into the front of the plastic contact cover. I removed the covers on both of the second from the right contacts so that I could clean them with an abrasive. These are the main ones.

Put everything back the way it was and the tape deck should work great.

Tape deck won't open

If this is a deck where the tape slides in horizontally, like most car stereo tape players, you may have a broken or slipping belt. The fact that you "haven't used it in a long time" suggests a worn-out belt.

In my car stereo, the belt slips when it's cold and won't play or eject the tape. After a few minutes, the unit "warms up" and the belt starts turning. Then everything is fine.

I think we both need to replace our belts.
