1: In most cases there are two FET`s gone you can use a normal IRF 530 but cut the heat sink from the FET do it with a pincer not with a grinding machine! (static electricity!). Before you switch on the set pay attention for the following parts!
2: The two coils that are mounted under the metal housing on the main board look of they have a other color if so they are burnt Check also the SMD parts under the main PCB.
3: The two SMD Elco`s that are mounted on the little PCB they have in most cases a high ESR. The value must be under 1 I thing that all the troubles you can have with this set are coming from this two elco`s (100uF 16 volt.)
4: look for a short cut on this little PCB pay attention to the two SMD gates. Measure the S/C over the +5 and +12 volt lines and check both PCB visual.
5: You must bring in a lot of heat to remove the both IRF`s use a good flux and do not fear the heat they can have it.
Because you must use a big Iron there is the danger to damage this aluminum layer check visual after you have solder the two FET`s all the connection with the smaller parts measure them with a Ohm meter. This was the fault in mine case there was a open connection to one of the gates of the FET`s

SOURCE: JVC RX-318 keeps blowing fuses

could be several things, speaker wires touching,shorted output transistors, a shorted rectifier diode,bad filter caps in the power supply,those are the most common

The likely cause of this is a dead short in the power supply. I don't receal the specifics of this unit, but there should be a set of four(4) diodes or a single bridge rectifier in the main power supply area. Check this/these for a direct short using a diode checker. Other than that, the output transistors being shorted can cause hte same symptom. Without seeing the actual unit, I can not tell for sure. If you know how, check the output transistors as well. Report your results here.

In my JVC RX 8SD only works a channel. How do I repair this defect?


Start with the simple things.
  • Check left right balance
  • Swap output speakers left to right
  • Swap the speakers at the receiver to make sure no wire open/short
  • Swap input RCA cables left to right red/white - white/red
Ok No JOY!
JVC has thermal overload circuits/overload on most of there Amps.

Remove power for a minute or two to see if there is a reset.

Rewire speaker connections to speaker set 2.

Connect REC out to Rec In swap cables and see if problem is in pre-amp or power amp.

Check internal fuses.

My JVC RX-801V has a short? The 5 amp fuze burns out every time I replace it. what could be the problem?


Probably the output transistors have blown or the amplifier capacitors are dried out.

Fuses are there to protect you and the device from further damage. Repeatedly replacing a fuse without fixing the cause of why it keeps blowing in the first place isn't a wise decision.

JVC RX 505v stereo receiver keeps blowing fuses. Replaced fuse with specified rating (125v 5 Amp) but still keeps blowing fuse. Fuse appears black inside and I see a flash when I apply power. Can...

My JVC THM303 will not work at all. took it apart to see if there was a blown fuse and the fuse is blown but do not know where to get on. The fuse says 51MS on one end and 125V1.6A on other


You need a 1.6 amp gma fuse, be sure not to get a slow-blow fuse.

Fuses blow for a reason (a short circuit). Not very often does it only need a fuse. I suggest trying only once if it blows again right away, take it in for service.

Home theater reciever


Check the internal fuses havn't burnt out. Remove the main cover. There are 4 glass fuses.
