Technics cassette deck M260 w/o pressing any button keep working

SOURCE: Technics RS-TR272 dual cassette deck

My RS-TR272 tape deck plays the cassette but no sound. I have not even used it much, may be 3-4 times in last five years. I tried demagnetizing it but still no effect. It is brand new unit, only thing I did last time was that plugged in the RCA cables in opposite ways one time (Output in In and In into output one). I am not sure if that had any bad effect on it. Can someone please help on this as unit shows cassette playing. There is no volume switch on the unit itself as someone else recommended in the previous answer.

Each unit (the EQ and the Processor) should have left/right in/out rca jacks as well as L/R tape in/outs. The EQ or processor use the receiver's tape loop and then provide a tape loop to replace the one they've used on the receiver.

You plug the first unit (let's say the Sound Processor into your receiver/amp as if it were a tape deck (Processor's outs connect to reciever's tape ins (play) while the Processor's ins connect to the receiver's tape outs (record).

Then you chain the EQ off the Processor in the same way (EQ outs connect to Processor's tape ins (play) and EQ ins connect to the Processor's tape outs (record).

Last you connect the tape deck to the EQ as follows. Tape deck outs connect to EQ's tape ins (play) and the tape deck ins connect to the EQ's outs (record).

This will put both the Sound Processor and the EQ in the receiver's tape loop. In order to have all the receiver's source signals routed through them you may have to engage a Tape Monitor switch or button somwhere on your amp which will route the tape loop to your speakers.

Can you give me some instructions on how to replace the belts?

THANKS

Suggest having a good clean and replace belts. If it stops around halfway on a C90 or near the end then there's a load problem on the take up reel, before halfway the supply reel.

The more detailed the description of the problem, the better for diagnosing the root cause. Thanks.

It sounds like you have a couple of problems. I'll address them as you have them numbered above.

1. Decks typically have belts to drive the various 'reel' mechanisms. Therefore, they can slip without breaking anything inside the machine or the tape. Your first symptom leads me in that direction.

2. That it migrated is mysterious, unless Sony is using a common motor to handle both decks' reel duties.

3. This symptom may have something to do with the root cause of both sides jamming...

Do the cassette well doors come off, say, for cleaning? Could they be dislodge? If so, they may have something to do with the jamming problems in # 1 and #2 as the doors play a part in positioning the cassette and holding it in place against the reel motor cogs. How do the doors operate with NO tape inserted?

Does it take excessive force to close the door only WITH a tape? make sure the tape is fully seated before closing the door. The capstans (directly below each reel cog) have to engage through the small holes at the lower edge of the cassette. They should be straight and clean. Any dirt or oxide on them will cause problems as these are what move the tape at the precise speed necessary for good playback or recording.

My hipshot recommendation, otherwise, is to look around inside the cassette wells very carefully for any foreign matter, debris, dust bunnies.

Do you maintain the deck as recommended?
