Unit works from remote only, buttons on it do not. How can I reset the unit?
I own a SONY CMT-EP505. It works only from the remote control. The buttons on the unit are not functioning properly. When you place one of them, it does something but not what it has to do. For example, when I push CD button, it fast forwards the tape.
So Ithink it needs a reset. I don!t know how to do it?
Can you help me?

Re: Unit works from remote only, buttons on it do not....
Look for owners manual at Sony web site. If there is a way to reset then that would be a good place to look. Doing a reset is a good idea. It could clear the "brain" on the unit. If a reset fails to repair then you may have a microprocessor problem. Something else that might be the problem, some units use a voltage "ladder" made of resistors to determine which button has been pushed. If the base voltage or ground is off on the ladder then all the buttons on that ladder will be interpreted wrong. Sometimes even just dirty contacts on the buttons themselves will cause that "ladder" step to be off when it is pressed. Good luck.

All of the presets I have encountered in the last years were thankfully simple; you manually tuned the station, then simply pressed and held the desired button until the display was stable (not blinking).
The unit will attempt an internal reset to start from a known position. If you are hearing mechanical noises, the unit is out of sequence and must be rebuilt. These are not the most straightforward units. If any portion of hte system fails the "startup" sequence, the entire unit will stop. Unfortunately, this may need to see a servicer.
You could try purchasing a 3 In 1 universal remote control unit.
These usually scan to find the matched frequency of your appliance, then you can turn on/off with the remote.
These are however limited, and you may not get all of the functions. As with the original remote as supplied.
Alternatively, contact your local supplier, they should be able to assist you further.
