Question about JVC RX-517V Receiver

Open Question

Unit not responding.

Out of the blue, the unit would not stay turned on. Turning it on in any mode caused it to stay on for a second and then shut down to standby mode. No messages were displayed, just the name of the mode it was in(phono, cd,tv/audio,etc). After trying the power button a few more times, to no avail, the unit stopped responding at all. No buttons will create any response. We finally just unplugged it. Dust could be a factor. I have looked for the jvc rx-517x owner's manual online to no avail. If there is one available, I will happily read it. We inherited the unit. thank you jen

There is some sort of setting you need to change on the JVC receiver. I had this same problem, and I read the manual and it solved it. You need to press and hold down a button to change the mode. Your unit probably says "TV Sound" right now. Once you press this button (not sure what button) like the manual says, the display should change to "DBS" and then it should work just fne.

SOURCE: Reciever Shutting Down

I replaced R916 with a 10 ohm wire wound resister and that fixed the problem on the unit I have. That resister is in serise with R 915 so they should be close in value. Both were marked 8 ohms but tested about 11 ohms on R915 and the bad one tested very high (over 1 meg) so I replaced it. When I first put it back together it didn't work but I noticed that the ground screw at EP901 was not retighted so be sure that all ground screws are tight and all conections are redone before testing with the power cord.

Good Luck,

SOURCE: JVC receiver shows power, but won't turn on

The above describes my same issue w/ my JVC RX-9010 receiver.
How do you determine if a transistor is bad? What equipment besides an analog multimeter would I need? I am out of work so replacing this is not an option. I can solder as well so if I can ID the transistor I gather I can repair this cheaply? Many Thanks!

I have an TX-SR313 for a year now and it was working perfectly until yesterday it just automatically shots off even when I turn it on for several time it just shots off. How can I solve that Problem?

Hello, It seems like the receiver is going into protection mode. A unit will only go into protection mode for two reasons mainly. The first reason is if there is an internal short. The second is if there is an external short which is typically only caused by one or more of the speaker connections. To isolate whether the short is internal or external, you would first need to unplug the receiver and disconnect all of the speakers. At this point you will plug the receiver back in with no speakers connected and turn the unit back on. Also turn the volume up to about 70 (even with no speakers connected). If the unit stays on that means that one or more of the speaker connections was causing the receiver to go into protection mode. If the receiver shuts off again with no speakers connected, then that means the unit would have an internal short and would have to go in for service. Thanks, FJD

Receiver shuts off when loud content comes on TV

Hello Jerry, This means that the unit is going into protection mode. The unit will only go into protection mode for 2 reasons. The first reason would be if there is a short within the unit itself. The second reason would be if one of the speaker connections is causing a short. To isolate which of the two is the issue, you would first turn the unit off and unplug all of the speakers. Turn the unit back on with no speakers connected and raise the volume up. If the unit turns off with no speakers connected then we know that the issue is internal and would have to go in for repair. If the unit stays on, that will tell us that one or more of the speaker connections was causing the issue. If that is the case I would check all of your speaker connections and possibly start with fresh copper connections. Thanks, FJD

Power on then off

Unit only stays on for 4 seconds then turns itself off.

This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

After turning ON the power/standby switch, the unit(receiver) display comes ON (green light) then after approx.4-5 seconds the display goes OFF and the unit defaults back to the standby mode (red light). I...

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Receiver keeps turning on and off also the standby mode blinks

The receiver is going into "protect" mode. This means that a problem has been detected and the unit shut down to prevent further damage. Without seeing the unit and taking some internal measurements, it is difficult to provide a complete solution. Typically, the output transistors fail which can cause this. There are other possibilities too. I would suggest that you get a detailed repair estimate from a local shop. With that information, we may be able to walk you through the actual repair.

Amp turns of after 2 seconds of turning on

It is going into protection mode, and shutting itself off. You have a short somewhere. I would suggest taking it to an authorized service center for assistance. This is not easy to diagnose, as it could be anything causing the short.

Try disconnecting everything from the unit, including the speakers, and turning on again. This will just confirm that the problem is the amp, and nothing external. Also, try connecting it to a different power supply/socket.

Unit turns off

This unit is going into protect mode because it detects a problem. The unit shuts down to prevent further damage internally. This usually is caused by shorted output transistors in the final stage of the amplifier. This is a simple fis for any shop that does audio repair. Expect a parts cost between $15 and $30 along with the local labor rate. If you wish to attempt this repair yourself, update this and I'll try to provide you with more details and instructions. You will need a multi-meter and soldering equipment.

Shuts down after 4-5 seconds

Your set does not have a display problem I'm afraid. The unit is shutting down because it is going into whats called the protect mode. You said that when you disconnect something the display stays on. That tells you that the audio amp is probably what you disconnected so the receiver does not see a short anywhere. You will need to have the output circuit diagnosed for this to work. Good Luck
