Rotel Recent Questions, Troubleshooting Help & Support

Turn off the other channel and listen only to the bad channel playing some music. Turn it up! If you hear any music the pre-amp is working and the power amp is faulty. If you don't, then the pre-amp is faulty. Because it's a stereo amp you have the good channel to compare with the bad. So you can do voltage tests, or "buzz" tests. Buzz Tests or where you apply a insulated tool to the circuits, a buzz will be heard. If it buzzers in the good channel it should in the bad. Ignore the power supply and don't short any parts out!

If it's an old type control then you can spray it with Servisol switch cleaner. You might have to take the top cover off to get better access.

It's more likely to be a fuse that's gone. If so it could be caused by faulty device on the heat sink. The only device that converts power is a Transformer. You can test this by simply putting a Volt meter on it's terminals. They are not hard to fit, however they have to be replaced by the same thing or one approved by Rotel.

try new battiers in the remote.

If you stored it in an area with high moisture content it is probably corroded at most of the contact switches. Capacitors also hate moisture, especially paper capacitors! The tuner is also probably oxidized inside. Now is the time to be brave and pull it apart, but first PULL OUT THE PLUG from the wall. Have at it with electric parts cleaner spray and clean, dry compressed air. If you believe that just because you stored it in your house, there was no moisture, think again! Radios like cars do not do well in storage unless you take precautions to protect them!
