Yes there is a fuse inside , but fuses will react with the amps and not with the voltage so your chances are low save your amplifier without replacing major parts

There is a fuse however, depending or if it was turned on afterwards , it will be much much worse.

it is possible there is damage as it will be likely that the fuses are not a semiconductor type ( really fast ) so overvoltage will have reached the secondary of the transformer and onwards to the rectifiers and capacitors and then to the voltage regulators untimately ending up on the boards via the DC rails.

This can cause significant problems with circuit components and more problems with the low voltage micros inside.

If you are really lucky changing the blown internal fuses may work, but could cause even more damage, so be prepared for an expensive repair.

If none of the above makes any sense then you need a tech or repair shop.

Hope this helps

Iplugged my jvc rx-7010vbk 120v reciever into a 220v outlet, does it have a power supply fuse that would burn out or is the whole power supply shot, what parts do i need to fix it


more than likely the whole board is shot
fuses only control current flow and break when that is exceeded
It is the voltage that does the damage that same as when you put 12 volts through a 6 volt bulb

Yamaha RX-V2600 completely dead ... any ideas


If it is plugged in to a working outlet, and the AC cord is not broken, there is a problem in the power supply of the receiver. This provides all of the DC voltages that make all functions work. If it is completely dead, the display, the lights, the audio, (everything) is not working; and it is not likely there are separate problems in all of these areas at the same time.

Yamaha RX-V3300 AC outlets are not working. Everything else works fine. Is there a fuse or reset button? I unplugged unit, waited >30 sec an plugged in again with no change. Thanks.


The total combined load allowed on the outlet is 100W. Make sure you are testing the outlets with a low-current device like a radio or low wattage incandescent lamp (25 or 40 W) or a night light (7 W). Also, be aware that you must have the receiver turned on for the device to work as the outlets are switched according to the main power.
If you still can't get them to work, it could be an issue with the fuse - you should take it in for service.

Yamaha RX-V793, Turn it on, 2 sec later turns off


Hello, welcome to Fixya!

Your receiver is having a power fault because it is not switching on. The receiver might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. If it doesn't power on, plug it into another outlet, to make sure there electric current entering into the receiver.

If plugging into another power outlet doesn't power it on then it confirms that the receiver is having a power fault.

When electric current comes from the power outlet into the receiver, it goes straight into the power supply board which then circulates the current into the unit. So if the receiver doesn't power on, the first thing is to make sure there is power entering into the receiver.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board. Once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect and solve the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Good luck.

Yamaha Rx-v730 - only hear "click" when try to turn it on


That may due to a bad power transistor, huge current flows when it's powered up, protection circuit kicks in and switch off the unit. Get to repair shop for check up and replacement.

Yamaha rv1000


ok yu problem has to be with the protection system before you burn it up it collapses to protect the whole system.....go direc to the thermal cut off devices on the main output and then to the power system......
