Question about JVC Audio Players & Recorders

Open Question

JVC RX-R75. The power outlet indicator is out. Is there a fix for this? I also read, if it’s out I should cut out some diodes. Is this true?

Please refer to the locations in my comments for your service manual to change out your diodes. Your going to need soldering experience to do this and careful for the high electricity with the capacitors.

From experience, a protection circuit has cut in, most likely due to a short in one of the DC output voltage rails on the PSU, thus giving the result of red standby LED, then green, then back to red. If the standby LED is not flashing/blinking, chances are you won't see any error codes.
This unit consists of several surface-mounted components, transistors, diodes, capacitors and resistors (many of which are miniature and often glued to the PCB) - this could become very costly, just in replacing modules as opposed to individual parts and spending hours fault-tracing looking for the problem which could cost a lot more in terms of labour.

I would recommend that you get a second opinion - take it to a service centre, obtain a quote for the estimated cost of repair (and fault diagnosis at the same time) - then you can make a decision after that.

It's up to you but before spending ANY money on it, throwing it out, or selling it somewhere as is, or whatever, get that second opinion from an authorized service workshop first. See how you go. *Nothing is impossible to fix, some things are complex.*

Testimonial: "I found a blown fuse near the back of the amp, I believe it would be the one for the 2 plug ins in the back. Going to try a fresh one and see how that goes. I only wanted this for a garage stereo so I may just chalk it up to a lost gamble. "

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

I have a jvc rx-518v amplifier with a burned out resistor on the imput board (r474) and diode (d474). They are severely overheated and the identifiers are gone, but the rest appears functioning. Any clue...


R474 should be a 18Ohm 2 watt metal oxide resistor part no. QRG022J-180AF
See page 2-9
and D474 is a zener diode part no. MTZ12JC see page 2-8.
