No power


For what amp, a Home stereo amp or a car stereo amp? Most car amps will not have internal fuses, but home stereo amps do have internal fuses. You will notice on car audio amps fuses are always plugged into the side of the amps or they have an inline fuse that is on the main power wire into it.
You have more than likely blown a Mosfet Power Transistor, very common in car amps, I'm fixing 3 of them right now with that problem. Class "D" Amps seem to have this problem on a regular basis and they are hard to get working again once they blow. You won't even see any evidence of the bad parts inside the amp either, old amps will fill your car with thick smoke and will have obvious damaged parts. Best bet is you will be looking at buying a new amp unless you paid over $500 dollars for it, it's not worth fixing, check the warranty to have it replaced by the manufacturer.

Amp burned


You might be able to have it fixed. Some amp companies make their own parts, so you would have to sent it to them. If you can find someone to diagnose the problem first, you could save yourself some money. I have repaired amps with parts from Radio Shack myself.

Need mosfets for hifonics amp sfp50n06


That is a Semiwell part I believe. It is an N-Channel power mosfet. Go look on their website they may have an alternate part you can use.

Xplore 2ch 200w amp model 4090 help


Yes there's a way to fix that. The best way to fix that is to bring it to your supplier (if it has warranty and in terms and conditions) or to a certified repairman in your area.

No sound, and a Immediat Red Light turns on everytime..whats it mean, and how can i fix it..


If it goes into protect mode with no speaker wires connected to the amp, it sounds like the audio output transistors have shorted. If that's the case, they would have to be replaced. It would require troubleshooting to find the shorted parts. You'd then have to disassemble the amp, desolder the defective parts and install the new parts. The following page provides the basic information needed to repair the amp.

Jensen A600HLX


These solid state amps have no user serviceable parts inside them as everything is soldered into place and your gonna need to know how to use a multimeter to trouble shoot the parts inside the amp on the printed circuit board. Sorry But without the proper training and the right tools you could cause more damage to the amp if you dont know what your doing. You cannot just open the unit and see whats bad. You must test each suspected bad part and replace it as needed. You should take the amp in to have a pro look at it, as there is no easy fix on these unless its an external fuse, and a fuse will very rarely blow all by itself. Good Luck

My JL audio 1000/1 amp does not work


Best bet is to send it back to JL, they do not sell the PCB with all of the components loaded on it. Most likely the transistors in the power supply have fried. Open it up and see if you can find any physical damage. Google the part numbers of the bad parts, and you should be able to fix it relatively easily. www.digikey.com is a great place for parts. Read this for more testing procedure: http://www.bcae1.com/ampfail.htm The whole site is wonderful, really.
