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.
There is likely a problem in the power amp section that only becomes apparent when the increased volume demands sufficient current in that stage to push the amp into a potential component failure situation. The protect circuit clicks in and disconnects the speakers from the amp to protect them from damage should the power amp stage experience a catastrophic failure. Unless you are a trained technician, you should have the unit repaired before major damage occurs.

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.
