Sony microcassette won't play beeps when you push play

You could try cleaning the the head. It is a small square shaped box that the tape runs across. Clean with rubbing alcohol on a cotton swab

turn the tape over

Probably has a bad sensor belt (small belt attached to silver and black reflective wheel).

I have the 3 of these units at my office with the exact same problem. Turns out, with a little tinkering there is a simple fix.

Open up the unit (by unscrewing the two screws underneath) and look for a brass disk with a black rubber band around it that connects to a small tip. The rubber band should be either stretched, broken, or even melted. This is the problem. Over time the rubber band deteriorates which causes the unit to not play a tape (rewind and fast forward operate differently).

Replace the deteriorated rubber band with a new one similar in thickness and size. That should work like a charm. Be careful if the original rubber band has melted. It is tar-like and will be difficult to remove.

Hope this helps.

here's the manual of this recorder. You can take a look at it to see if there are any explanations regarding the error:

Hello,

This unit does not have erase. You can use a microcassette tape eraser which you slide the tape thru.

You need to reflow your motherboard with a heat gun. You have ylod or yellow light of death. Easy fix.

Hold down the 'Erase' button and press the 'Rewind' button. It will erase the tapes as it rewinds.

Just talked to Exec. Communication Systems. He said that the play motor is not turning (the rewind and fast forward uses a separate motor) and the problem is either the belt or the motor. They can repair them at $82.00 plus parts and shipping.
