Buttons on the stereo, sony zx66i, will not work but the buttons on the remote do. Unfortunately, there is no button to open the 5 disc changer. Is there a reset button or way to fix it so that the buttons work again. I can turn it on but not off and no other buttons work at all except the volume. We need it for a party on Saturday (today is Wednesday) Please help!
SOURCE: Unit works from remote only, buttons on it do not. How can I reset the unit?
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.

remove knob and use some pressurised air to blow out any scum thats built up. yes a remot would still work.

it a bit complicate to open
you can try but you need to remember what you open so you can put back in the same order
try this
first open the back cover you should be able the see the inside then you need to open the top cover now the changer can be open without power you need to locate the motor and turn the the belt or the wheel slowly and it wil take the disc out. """"""dont turb back""
you need to plug the power and let it go back alone after that disconnect the power and put back everything
its not so easy so before you do it make sure that you can open and put back
Hope it will help
