    Could be a "poor" solder connection causing DC leakage problems. Use a "clenched fist" to lightly vibrate top, bottom, sides of chassis and see if issue appears/disappears.

Sounds like DC leakage....pre-drive and/or output transistors (or IC) becoming intermittent often pass DC voltages to the speakers. The "pops" you hear are these DC pulses being passed to the speakers and the "cutout" is the protection circuitry doing its job...protecting the speakers. Speakers want AC voltages...plus voltages moving the cone in one direction, and a negative voltage moving it in the opposite direction. DC voltages push the speaker cones in a single direction and hold it there until it fails. The bad news...it's repair shop time.

    Thanks for that. I have been researching this extensively. I'm pretty sure it the op amp out put to the front left and right channels. Once I get the amp disconnected from the many wired connections I shall properly bench test my theory. I just hope the parts are still available. Kind regards . matt

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.


Check for loose speaker connections as a root cause for intermittent shutdown.

I have a Sherwood RX-4105 Receiver and I am getting no sound through my speakers and the connection with the wires is good so its not that. Any Idea on whats wrong?


when you turn your computer you should hear a sound of a relay initially and after about two seconds another sound, is the closure of the speaker relay models if you do not hear the sounds, the team has some short audio output.

RVD 6090R Stopped working after a very brief power outage.


Hi cleitner . It has most likely blown a mains power fuse. You will need to FIRST DISCONNECT FROM THE POWER. Then remove the lid and check internal fuses. Best done with an ohms meter to be sure that you don't miss any. Some fuses can look ok but be faulty. Replace any blown fuses with one of exactly the same type. If you are not sure what type of fuse you need, feel free to get back to me here. Good Luck, thanks for using FixYa
