Re: Protect power keeps coming on - rdx5 MHC
Protect usually means a speaker wire problem. remove all connections and redo them making nice tight twists in the connections the spliced end should be no more than 1/4 inch long. make sure to do this for all speakers as well as on the back of the unit.

Your stereo went into protect mode to prevent complete failure of the amplifier inside that radio. Most of the time this happens from playing the stereo real loud for a real long time and it overheats. Most of the time disconnecting the receiver/stereo and letting it cool all the way down or at least 5 minutes and then reconnecting it to the power source will reset the protection mode. You want to make sure you are keeping the radio cool. Don't stack anything on top of it and try keeping a small fan blowing on it to expedite the heat out from the unit. Also turning it down every now and then to let everything cool down a bit will help prevent it from going into protection mode as well.
Hello, the protect circuit is likely detecting a damaged speaker or speaker wire.Check the unit with one speaker at a time connected, or if you have an ohmmeter measure each speaker they should read approximately 8 ohms.When you connect a speaker thats bad the unit is designed to shut down and flash protect.

whan a unit goes into protect, it could be a bad speaker, shorted speaker wires. or the most common fault is a blown audio o/p ic in the unit. due to being compact units they are more difficult to work on than the full size unit. the part typically runs between $25.00 to $75.00 usd. if you are good with working on small places and are good with soldering give it a try. the ic will be on a heatsink.
