Sony BM-23 portable dictator problem
My BM-23 will PLAY a tape for a few seconds then stop. As it stops there is
a high pitched signal that will continue until I put it on STOP. Sometimes it will stop playing and I can hear the motor spinning, and after five or ten seconds the high pitched signal will come on. Sometimes it won't play (the tape won't move) but I can always hear the motor spinning. Often, when it won't PLAY at all, if I put it in rewind then release the slide, it will play for the above mentioned 5-10 seconds before stopping and signalling. At the same time I notice the LCD counter is blank, no readout at all. The batteries check out with 1.28v in each. When I listen to the motor spinning, it seems strong. I know nothing about this, but sounds like a belt slipping, though I don't know if that would cause the LCD counter to stay blank. (even when I can get it to play for 10 seconds, the counter stays blank, no blinking, no flashing, no text. If this is a belt, is it easy to disassemble this small dictator to replace it? This is a real good dictator so I'd like to figure out how to fix it. Can somneone give me advice on this... Thanks, John |
