Question about JVC 500W 5.1 Channel Surround Sound Receiver

1 Answer

No power I powered up the receiver when it was erroneously connected to an ac outlet which was on a dimmer ( don't ask me what **** installed that). I got the red standby light but when I tried to go full power - there was a buzz. I hit the power off swithc but now, despite being connected to a good ac outlet, I get no power at all. Have I fried my receiver? Warranty is 2 months expired. Cathie

Cathie, What **** installed the dimmer? Sorry you said not to ask. No power and no stand-by light, it may need a stand-by power transformer or the main micro. If the stand-by light is on and the receiver clicks when you push the power button it may only need a fuse. Make sure you replace with a fast acting fuse of the same rating for current (amps). NOT WITH A SLOW BLOW FUSE!!! If it blows again there is somthing shorted and it needs service.

Unit won't turn on. There's power to the outlet but the reciever just won't light up! Sony STR-DE 197 It's only a couple of years old and shows no damage.


Failure of the the power source. To see if it's fixable the receiver will have to be opened and the power board tested . This job requires at least a basic experience in electronics - if you don't posses it all you can do is to look for a burned fuse or damaged capacitors. For them follow this

I need to know what amp fuse i need for my yamaha htr5840 receiver. i pulled out the blown one, but it only says 125 v. it does not tell me the amps.


The power consumpyion for yor amplifier is 350W / 440VA and the 2 switched AC outlets at the back panel can handle up to 100W, totally 450W. I suggest you to use a 5A / 110V fuse and in case burn down use an 6A / 110V fuse. DON'T INCREASE these values, you may damage the amplifier.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Don't tell us you fell for the scam. Don't expect any support from the manufacturer. Google it. Call the cops.

I have a caver preamp high fidelity control console model c- 4000 and I have a power amp.I don't know how to set it up to work thank you.


Can't find the manual.

Outs to Ins. Only connect a turntable to a PHONO connnector.

http://www.canuckaudiomart.com/view_images.php?cat=Preamplifiers&catnick=preamplifiers&cfid=193374&image_id=1831037

MAIN OUT to the unidentified amp's IN.

Don't slave too much power-hungry gear off the convenience outlets of the preamp.

My AV receiver turns off a couple of seconds after I turn it on. I did what the manual said, unplugged the power source and removed all of the speakers but it continues to do the same thing. Anything else...


Hi,
you may have a bad Earth power 110 V AC cable connection which makes such hum / buzz even nothing connected..
Check the connections between components and make sure they are secure before proceeding to the next Step. Sometimes, loose connections can cause a hum.
  • Separate the audio cables from the power cables; electromagnetic interference from the power cables can cause stereo hum. Use cable ties to secure the audio cables away from the power cables.
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • 5 Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    Major hummimng noise when sub is connected to receiver.


    Is the hum in the receiver-attached speakers or the sub?


    Self-powered sub?


    How is the sub attached - RCA or speaker-level?


    Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.


    If it hums with the sub attached, unplug the sub's power cord. Differences in AC ground potentials will generate hum across linked devices.

    There is a significant high pitch running through my speakers. I checked speaker wires, & plugged in power cord into a different outlet. Still no luck. Any suggestions?
