Suddenly blows fuse as soon as plugged in why?

Usually a fuse blowing immediately means there is a short in the amp somewhere.

There is no sound coming from the speakers on the SC-HT900 dvd home theater sound system. It used to make a loud pop sound but then would still work. Now it does not make any sounds. The dvd will play...

May be a fuse inside blown , if it makes a loud pop that can take out a fuse, If you find one blown , replace with same type and try machine .Dont replace with higher rated fuse though , if it keeps blowing. Try using headphones and if you get sound , may be speakers.

Power amp for pa system stopped working

Sounds like you have a power supply problem in the amp. I am assuming the fuse you are replacing is intergraterd into the AC connection. You need to dig deeper. If you are not an electronics person you will need a tech.

My sony receiver tuner wont turn on. It was working fine yesterday now it wont power up. The fuse near the plug wire inside is good. Any suggestions

Fuses almost never go bad something causes them to blow. Even when a blown fuse is found in electronics just t replacing it can cause more damage if something caused it to blow, a repair person looks for bad parts before replacing a fuse. Only microwaves are known to blow fuses and replacing the fuse fixes it. About the only thing that people can do is unplug a short time and try it again. And need i say is the power outlet ok.

The unit won't power on at all.

You can try replacing it with any 10 amp fuse just to see what happens. If a new fuse keeps blowing out then you have a shorted power amplifier inside(they consist of transistor or a single chip). These device look normal most of the time short out with any visual indication. If you desolder the power amp chips(they are mounted against an aluminum heat sink to dissipate heat) and the fuse quit blowing then it is the problem.

Turn it on and blows fuse replace fuse and plug it in and it blow

You need to have the receiver serviced. The fuse is blowing because some part in the power supply or amplifier section has failed. A service technician will need to troubleshoot the unit to determine what parts need to be replaced.

No Power on rt2580

According the parts list on the model unit your fuse is suppose to be F101,FUSE 6A 125V. Is it possible that you have an undersized fuse?

I don't believe that one amp differents would cause your unit to blow like that but, you never know. More than likely you have a bad component in the power supply or power amp.

Then again, with an average replacement cost of $150 online; it not worth getting too deep into the repairs.

Fuse keeps blowing in the subwoofer on my Philips hts-3450

Replace the capacitors with ones of the correct v. Download latest manual from Philips website to verify if the capacity value is not a typing error.

Koss 2503 blows fuses

You could be having problems with just that outlet  It might not be able to handle that much electricity.  Try the system on a different outlet.  If it still doesn't work, try the system on an outlet on a different fuse.  On an overloaded fuse something as simple as curling iron can blow a fuse.  If none of these work then it's probably a power supply issue.  If the power supply isn't grounding right, this could be causing the system to overload and blow a fuse.  The only way to fix this would be to replace the power supply; however, this might not be practical or possible.  I would suggest simply buying a new system, but if you're up to it go ahead and try to get a new power supply.
