sansui TU S7

i am not sure if its a dirty switch problem (still try to clean them) but it could be something internally. Are you using the correct voltage? do you get any sound? Does your memory channels get deleted after a while? i am sure it is something internally
 
This is a digitally synthesized tuner, so no moving parts (like tuning capacitors) except for the switches and controls. It could be a damaged or oxidised switch, but also very likely could be an electronic fault.

If you could find a service manual you could check the PSU voltages are correct and are present everywhere they should be. If still nothing obvious - then I would suggest only a good tech' can get this working.
 
yeah, i tested it at correct voltage setting. this is a 220v equipment. no sound, but it has display. been looking for a tech.
 
Just noticed that your Number of Posts is also "stuck" at 3. Seems strange.
It should increase as your Posts increase but does not seem to be the case.
Just wondering ...
Robert.
