I have a jvc RX-550V receiver and when i plug it in the standby red light turns on but the display does not

1. Reset the receiver: To reset your JVC RX-5060 receiver to its factory default settings, switch off the receiver and unplug it from the power outlet. Press and hold the "Power" button on the front panel for approximately 5 seconds.Then, while still holding the "Power" button, plug the receiver back into the power outlet2.
2. Check the fuse: If your receiver still doesn't turn on, check if there's a blown fuse in the receiver.If so, replace it with a new one of the same rating3.

If none of these steps work, it's best to contact a professional or JVC's service center for further assistance.
I hope this helps!

Model?

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.*

From the remote control only: Press MUTING to turn off the sound through all speakers and headphones connected. "MUTE" appears on the display and the volume turns off. To restore the sound, press MUTING again. Turning MASTER VOLUME or pressing VOLUME +/- also restores the sound.

They don't overload from missing speakers. I'm curious, what buggered the one speaker?

Examine all of your speaker wires carefully to be sure no unintended contact is made between them and anything else.

Is "overload" being displayed?

“OVERLOAD” starts flashing on the display.

Speakers are overloaded because of high volume.

1. Press STANDBY/ON on the front panel to turn off the receiver.
2. Stop the playback source.
3. Turn on the receiver again, and adjust the volume.
----------------
Speakers are overloaded because of short circuit of speaker terminals.

Press STANDBY/ON on the front panel, then check the speaker wiring.

If “OVERLOAD” does not disappear after turning on the receiver again, unplug the AC power cord, then plug it back in again.
If speaker wiring is not short-circuited, contact your dealer.

sorry but this is an electronic malfuction or failure , it will need repair
leave it unplugged to prevent further dammage untill you can take it to your local electronic repair shop

Yes this is a power supply problem,you better replaced the regulator IC there or replaced the whole board,so it will works normal again..


hope this may help you;

DON'T FORGET TO RATE:

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

i have this problem but i dont have a cable box, if i use rca's i get sound but optical cable nothing

have a jvc home theater with this next problem, when I turn the display lights up then see the name overload and shuts down the display, and it does not connect the speakers
