How do I fix my home audio pioneer amplifier from blowing the 6.3Amp fuse

I have replaced the fuse five times. I have cleaned out the inside of the component. I have moved it around the house to different plug ins.

If it does blows off fuse; as soon as it is switched ON; either its mains rectifier section circuit; or its audio output section circuit will have any kind of short circuit. Contact any service technician. Your set need a though check-up. Never insert a fuse, and check further; till the fault has been rectified. It might make things worse.

How do I fix my m-770 amplifier fromm blowing the 6.3A 125v fuse


There could be a short in one of the wires or within the amplifier itself! Check the speaker wiring first!

I parelled one 15" q power subwoofer to my brideged pioneer amp.The amp got really hot and blew a fuse.How should I wire my dvc subwoofer to the briged amp.


Hello sir, hi, YOU DON'T bridge no more speakers, this upsets the impedance load of the amp. to install another sub-woofer, get another amplifier. You may have damaged your power amplifier, If you experience repeated fuse blows, your power amplifier is now SHORTED. This needs IC amplifier replacement.

Blown amp possibly?


i have the same amp with the same problem.....your best bet is to do what i did get a better amp(audio pipe,spx,kicker,punch,etc) do not get pioneer amp or sony anything

Avh p5700dvd ..Noisy distorted sound from RCA output


This model of Pioneer has a common problem with a couple of fuses that are inside the unit mounted on the main circuit board that will blow. These are surface mounted fuses, and must be replaced with the same type of fuse. They are very small and white colored and require some good soldering skills and the proper soldering equipment do this job properly.

I work at an authorized Pioneer service center and have seen this problem many times. These units are very difficult to open up and work on. It is very easy to damage the ribbon cable that connects the flip out monitor to the main circuit board if not done perfectly.

What you can do as a work around for a short time, until you can get it in for repair, is this shortcut. It will restore your audio, but should not be considered a permanent fix.

At the amplifier (since it is easier to get at than the RCA cords coming out of the back of the Pioneer) you need to connect a jumper wire from the RCA ground on the jack to the power ground on the amplifier. The outer metal part of the RCA jack is the ground, the metal pin in the middle is the positive.

Remember, this is only a short term temporary work around and is not a permanent repair. You just need to supply the RCA output ground with a good ground.

The repair of replacing the surface mounted fuses can cost anywhere from $100 to $160, depending on the service center rates. Just don't wait too long, or play the amplifier too loud in the meantime.

My Pioneer GM 5300t amplifier blows fuses all of the time. It says to have two 30 watt fuses in it and thats what i have yet they still keep on blowing. My subwoofer is a Pioneer TS-W302R Twelve-Inch


Do not continue to put new fuses into the amp until you have figured out what is causing the problem. It will only increase the chances of causing more damage to the amplifier. I have been repairing car and home amplifiers for over 18 years and have a lot of experience with Pioneer amplifiers since I work at an authorized Pioneer service center.

This post will be long, but if you bear with me and forgive my long-winded answers you may be able to determain your problem even tho I really don't have enough information to figure it out yet. If not, we can get a little closer with more information.

Does the amplifier blow the fuse as soon as you connect power to it, or as soon as a new fuse is put into the amp? If so, the amplifier has some shorted components in the power supply. They have a bank of mosfet transistors in the power supply that sometimes get shorted when the amp has been pushed beyond it's ability, or just from a random part failure, or if the impedance of the speakers is too low. Your speaker is a 4 ohm speaker, if it is at a lower impedance than 3 ohms when measured with an ohm meter then it will need to be replaced. Even if it still plays, it is too low of a load for the amplifier and will cause more current to go thru the amp than what it was designed for. If you are using more than one speaker and have them bridged it will do the same thing. This amp is rated at 4 ohms bridged and 2 ohms per channel stereo. When you connect 2 speakers together and then bridge them they become a 2 ohm load which causes double the amount of current to flow thru the amp. It was not designed for that. Sometimes you can get these component failures just because there may be a solder joint or two inside the amplifier that is cracked and not making connection very well and this can cause components to short out because they are not operating at the proper voltage.

If your amp blows the fuse only after it has been turned on by your head unit, you will most likely have a blown channel. This would require the replacement of the output transistors of the bad channel as well as a few resistors and sometimes a few other parts.

If your amp will turn on and play for a while and then blow the fuse at higher volume levels or after a long time playing the problem can be either a bad speaker at a lower impedance or one or more components that are breaking down after they get hot or at a certain volume level.

As you can tell by now there are many reasons that an amplifier can blow the fuses, and figuring out just what the cause is can sometimes be a difficult task. It may require that you have a multimeter to do some checks on the amp and a power supply to power the amp on a bench so you can do those tests.

If this information has not helped you to determain the problem, please give me as much information as you can about how you are using the amp. How many speakers, where they are connected, at what point does the amp blow the fuse, and anything else that you can think of that may or may not be important. You never know what might give a better clue, too much information is always better than too little.

Thanks and good luck,

Dave

Blown fuses


there is a possibility that the current load is excessive nor there is a short circuit from elsewhere, do not try to install again a new fuse unless you are certain there is no shortages of any wire from inside the amp and throughout the system by physical inspection

also install the right value for your fuse meaning the right amp and voltage, high temp is an indicator of shortages and defective power transistor
