    TYou have a problem with the standby circuit, if the smaller transformer has volts before and after then start checking the regulators.

SOURCE: I have a jvc RX-550V

The display is back-illuminated by small incandescent bulbs. Burnt out bulbs equal no display, although the chances of several bulbs failing at once is not high so the power supply for the display/bulb assembly is a good place from which to start fault finding.

It needs a repair shop - as a user there's nothing you can simply dig into to fix.

SOURCE: my jvc is not working

If you're needing to run it at max volume something else is afoot.

ANY amplifier has specs. Those specs are at a certain output into a certain load yielding a certain amount of distortion. That is not to say it can't push more power. But you can be sure the distortion figure will rise almost vertically as the power spec is exceeded. Eventually the signal will clip and now we're talking about danger to the amp and the speakers. Protection Circuits are designed to detect and intervene in these cases.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

SOURCE: can a ten band equalizer be used on a JVC rx-8030v 6.1?

Yes.

Use the Tape/MD or the one next to it (lower)

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. "

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.

My jvc RX-5020 VBK IS NOT WORKING AT MAX VOLUME,ON SCREEN APPEARS OVERLOAD SOUND STOPS AND I HAVE TO TURN IT OFF AND TURN IT ON AGAIN ! WHAT IS GOING ON???


You must be using speakers with lower impedance than what is recommended. This causes the amplifier to over load at high volumes.The protection circuit shuts down the Amplifier to prevent further damage.
And please remember no amplifier is designed to run at full volume, same as a car speed - Even though the speedometer might show max: speed 200Miles per hour would you do it???

Rx-dp15b reciever turns on, then immediately goes into standby


Just worked on a Sony with a similiar problem. I replaced the Power Amp Drivers. They were labeled as IC's on the circuit board. They were relatively inexprensive, around $33 total. This fixed required knowledge in using a Soldering Iron and Desoldering Wick. Also I had a schematic of the circuit board which can be purchased on the internet. Hope this works for you. It might be best to just have a tech look at it, if you have no electronics knowledge.

JVC RX558 VBK, Crackling noise from speakers


A quick quess of mine is the following:

The OVERLOAD indicator lights up when the receiver is maxing out on the current it is sending to the speakers. My guess is there is possibly something wrong with the receiver itself, especially since the B speakers won't play. Either that, or something is broken in your speakers or you are using a set of speakers that have too low an impedance rating for your receiver.
