Jvc rx 5052 overload when volumes open


Could be....
  1. There's a short in your speaker wiring somewhere
  2. or a blown speaker
  3. or you are recycling the speakers from an old all-in-one system and they're too low Ohms
Check your speakers first. If they are less than 8 Ohms, or there's no label on them which gives the Impedance (in Ohms) then I'll lay money that they aren't suitable for the amp. Stop using them and get some proper 8 Ohm speakers.

Wiring shorts might be only a single strand of copper wire. But it's enough that at higher volumes it conducts enough current between the speaker terminals to trip the amp's protection mode.

Fix the problem. Go through your wiring. Check using a torch. If all looks good then it's a blown speaker.

Remove the speaker wires from the amp. Switch the amp on and turn the volume up full. The amp should stay on. Turn the volume down and switch off.

Now connect ONE speaker only. Try the amp on and volume up again. If it trips out then that's the faulty speaker. Repeat by adding one more speaker each time. When the amp trips, the last speaker added is the culpret.

If you've done all the simple stuff, then what's left is a problem with one of the output transistors. It needs the output transistor(s) replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.

I inherited a technics SL-6 turntable system and a very old sears audio by fisher am/fm stereo receiver along with 1 pair of kenwood ks-401ht front speakers and cant get any sound. I have the technics...


Your connections seem to be right.

Let's distill this down to its simplest configuration... does the onboard FM produce sound? If not, nothing will.

NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control may have developed a high-resistance or 'dead' spot through idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

HOOKED ALL MY SPEAKERS UP BUT SUB AND CANT GET ANY SOUND FROM FM OR TV THAT I HAVE HOOKED UP AM I MISSING SOMETHING ALSO THERE IS A LIGHT THAT SAYS SOUND MUTE BY FM


From the remote control ONLY:

Press MUTING to mute the sound through all

speakers and headphones connected.

"MUTING" appears on the display and the

volume turns off (the volume level indicator goes

off).

To restore the sound, press MUTING again so that "OFF" appears

on the display.

• Turning MASTER VOLUME on the front panel or pressing
VOLUME +/- on the remote control also restores the sound.

My tuner will play for a short time (fm radio)then shut off with a loud click and the message "OVERLOAD" appears on the display. Help! Thanks.


This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic.
1. Remove all speaker wires. 2. Keep the volume down - all the way. 3. Turn the unit on. 4. If it does not trip off, then there is a problem either in a speaker or the wiring. a. Reconnect one at a time until/unless it trips off b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.

Regarding a Yamaha RX-V757 receiver, if I have my volume set above approximately -28, whether I'm playing a DVD or listening to a music CD, the units power shutsoff. When I turn it back on the display says...


Try turning up the volume with just the FM selected (and tuned to a station). If you can adjust the volume to an appreciably higher level when simply tuning in a radio station, then your CD/DVD player may be outputting a signal with a DC offset, which is getting amplified when you turn up the volume, and past a certain point the protection circuitry is sensing too much DC being sent to the speakers and shuts the unit down. If the unit is getting hot, there is likely an internal problem, or you have a shorted speaker wire, or even a bad speaker. Replace the speaker wires as a test, and you can also run the unit with only one speaker connected at a time to see if any are the source of your problem.
Yes, it's possible that there's nothing wrong with the wires or the speakers, and the unit simply needs a trip to the shop, but it's your job to rule out the easy stuff before you pack it up and take it in.

When I plug my Onkyo receiver in it turns on and off on its own in intrevals of about one second. Is this a bad power supply or something else?


follow these steps:
*disconnect everything from the unit (treat it as if you just got it out of the box) no speaker wires no cables.
* turn on the unit and max the volume (w/o anything connected)
*if the unit shuts off during step 2 you need to send it in for service (go to onkyousa.com for the nearest service center)
*if it didn't shut off during step 2 you need to play the tuner and connect one speaker at a time.
EXAMPLE: connect your left speaker and then play the FM and then max the volume for about 2 seconds then turn it down.
if you were successful in maxing out the volume on the left speaker continue with the other speakers until you isolate w/c speaker is causing the issue. if your gonna ask why the FM...its because its a direct playing source but you can still use a cd player or a tape deck to try it out.

take note: if your receiver shuts down on a speaker that you have connected make sure to have that speaker checked or better yet replace it.

Overload Problem


If your rec'vr worked with the original front and rear speakers, the new speakers are either defective or ar the wrong impedance.
Also, I find this confusing: "I connected the wiring for 1 of the front speakers to the connection on the rear of the receiver". This may indicate wrong wiring connection. Make sure you have connected the speakers properly
