    shawn... indicated that his solution for
    STR-DE345 5.1... Problem
    is valid for all Receivers

    check to see if you put the correct fuse in the receiver, and if it is the correct one, you will need to check the protection circuit because with it being turned up so loud the amp was probably damaged. in most cases with protection circuits you will probably find your problem with an output transister. than check for blown caps.
    sorry but I'm a little illiterate when it comes to technical terms... So what am I looking for? where is the protection circuit? how do I know if something is wrong with it? same with the output transister and the caps? Thanks !! : )

Rx-v390 when i trun on power after few second auto shut off.. what could be the problem I changed all Fuse (4A 125V) still have same problem.

The problem is with either the Amplifier or the Speakers.

If you disconnect the Speakers and then turn back on and get the same fault then it is the Amplifier.

If it stays on OK then you need to turn off again and connect one Speaker at a time (turning off again between each one) until you find the fault Speaker.

If it is the Amplifier thats faulty then it could be a simple repair that would involve replacing some Capacitors but you would need a Soldering Iron and the knowledge how to de-solder and re-solder components to a PCB.

If you need any further assistance then just ask.

I am now having a very similar issue with an av 100 unit I have had for quite some time now. Bought replacement fuses for it the same exact size and they keep blowing as well.. one thing I notice in the original fuse is that there appears to be a resistor in the fuse case.. maybe it requires a special fuse.

I had a bad speaker wire on my Pioneer vsx-305 and the 125v 6.3a fuse blew. Where could I find a replacement fuse?

You can get fuses from any electronic parts shop, such as Maplin (UK) or Radio Shack (USA). I would get a few, because chances are the fuse did not just blow because of a bad speaker wire! Fuses are there to protect the device from an overload (which would cause a fire). The mostly likely cause of your fuse blowing is that your wire shorted out an output transistor on the channel the speaker was connected to and the transistor is acting like a piece of wire now!
If you have an Ohm meter I would put it's probes on the terminals of the transistors on the heat sink. You will soon know, as it will be just like you have touched the meter's probes together!

I have the same problem. The fuse blows every time I plug the Sony STR-DE135 into the wall. I did not find the F901 at Radio Shack, so I bought a fast acting 5 Amp 125V Fuse at the Hardware store. It blew...

There is usually one or two normal clicks on power-up. A self-protection relay activates after a short delay for circuit and power stabilization plus some internal cheking for shorts and thermal issues.

If it keeps blowing fuses you are stressing it a bit more every time you feed it another one. I'd get it in to a Pro for repair.

Receiver had blown 4A 125VAC fuse; is this a fast acting fuse or a slow blow type? Will it matter if I use a 250VAC 4A instead of a 125VAC fuse?

Yes you can use a 250 one. It's the amps that's important. On the other if you can see the remains of a coil on the original fuse then it's a slow blow.
However the fuse might have blown due to a short in the power section or audio section, so make sure you have plenty of fuses!

Sony STR-DE945 8A 125v fuses

Check HomeDepot they have 7amp , maybe your store has 8amp.

Are 2 - 125V 5 amp fuse good enough to use just to check and see if this works...was working just fine. no wires i looking at a large problem?

Fuse rating would be written on circuit board fuse located, yet 5 amp fuse will work to test the receiver/ amplifier.
If fuse blew off again, then amplifier has problem either in power supply or amplifier output section.
Qualified Tech will fix it.

HTR-5280 Receiver Fuse Blown

the fuse rating should be printed at the back near the fuse holder itself. If it opens the fuse again and again probably you have a circuit loading problem in the receiver...either one of the amps is failing.

I have a older sony STR-DB830 receiver that keeps blowing two fuses labled f801 and f802. They are 125v 8amp. They pop the instant you turn the power on. Something is shorted, but I can't find it. Is this...

hello, i believe that your problem is in the audio output ckt, check all the transistor you have one bad channel (shorted transistors). with a soldering iron disconnect them and check them with a meter.

good luck

Kenwood KR-A4070 blowing 5a 125v fuses

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.
