This kind of thing is impossible to "fix" remotely.
Check the bridge rectifier first then suspect the Class D output module on the heat-sink. The main smoothing capacitors, I have had one go completely open circuit but I wouldn't suspect one of going short circuit (Would only blow one fuse).
I have not been able to find any circuits for this model as I have two of these subws myself.
Anyone found any?

I have shorted left speaker output by leaving the speaker unplug...the two wire shorted together and blown something, someone got an idea of witch component i should replace? thx


Probably took out the output transistors for that channel. Is the unit dead now? Usually in these models, if the outputs go, it takes out the main power fuse.

Denon AVR-4806CI won't turn on.


you must check first the fuse in the power supply which getting blown.if the fuse blown with darkened black color that was mean there are other component parts in the power supply or in the board which get bad. if you know how to test component, check shorted bridge type diode as will as regulator ic and FET transistor in the power supply board.

PIONEER VSX815-K NO FUSES BLOWN BUT NO POWER TOTALLY DEAD NO BLINKING LED NOTHING, PLEASE HELP!!!


How do you know no fuses are blown - you have to check with a multimeter. Are you sure the outlet has power? If the fuses are fine and there is for sure power, then it may be getting power but the capacitors are shot or something else internally is blown. It sounds like it's probably beyond your scope and should be brought in to an electronics repair shop.

One of my polk audio RT800i tower speakers began smoking while watching tv I quickly disconnected it and it no longer works. how can it be fixed?


Since they're not self powered I wonder how much audio power they were absorbing at the time or maybe how mouch distortion, as THAT kills speakers faster than clean power. The only things that can burn up are the crossover and the individual drivers. I can't find anything about a fuse, which almost certainly would be blown, or should have. A blown crossover probably wouldn't affect the woofers. You COULD access each driver and test each with an ohmmeter for dead short or infinity.

I have a sansui g9000 and 2 of the speaker wires crossed and shorted out that side of the receiver. how can i repair this?


You have probably blown the semi-conductors for those channels. They will be found on the heatsink. I recomend that if there are two transistors for each one of the dead channels that you replace both. Even if you discover only one has shorted. There may be a fuse connected to them.

Stopped working


I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.
