Static on left front output

I need a schematic for a JL audio 500/5. Left front output has static. Not sure if it's a transistor or resistor. Even with no input source (on bench). Can't find a schematic anywhere!

If the service manual is not available on the JVC websites then you should just Google search "JVC A-GX3 service manual" There are many websites that archive manuals. You'll probably have to pay for a copy. Why can't you disassemble the unit and see the output transistor numbers first? More importantly how do you know this is the fault?

Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...

There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.

Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.

Hi...
Flush all the switches and controls with De-Oxit D5 or better.
Then get back to me.
Thanks

JL Audio 250/1 blown power trans blown resistors possibly shorted transformer How do I test


You should get the schematic for it. I can tell if your reference to trans is for transistor or transformer. If you mean transistor, in that power circuit they are most likely http://www.mouser.com/ProductDetail/Vishay-Siliconix/IRFZ44PBF/?qs=sGAEpiMZZMvARmQSk64rFx%252biHG2Aqv9T. See if you can see any references to the parts on the board. One of the others that fails often is: http://www.mouser.com/Search/ProductDetail.aspx?qs=4kLU8WoGk0vGgdnitUP0Eg%3d%3d and

Left front and left rear speakers do not work, they produce some sound but mostly static. The "phono" rca jacks also do not work.


Hello,
First off make sure that the cables you are using are functional. Also,check and verify the locations of the connections. You need an audio output from your source to an audio input at your receiver. If you run a video output from your source to an auido input on your receiver that will create strange sounds

I have bad static from my Pioneer vsx 49 Elite


sorry no easy solution as it sounds like the output transistors blew out or the emmitter resistors. you will need a service manual and an multimeter to measure the resistors on or around the audio output transistors they are a low value resistor usually around 1 to 2 watts in size. Do not replace any bad , burnt or discolloered resistors around the audio output transistors as if tou do you might just cause more damage to the output transistorsor audio output stage including the audio driver stage of the amp!!!!!!

Need resistors for JL 500/1


If you have the old ones that you are trying to replace, Radio shack has tons, as well as guides to show you how the bands are deciphered. Hope this helps

Yamaha RX-V596 main rigth channel problem


The right or left (side) output channel has blown out. If it uses discrete transistors you'll have to replace two of them (one PNP and one NPN) along with several resistors that are part of the circuit (I'm guessing the static occurs on any input source).
Now , if the static happens only on certain input, then the problem should not be in your amp.

Speakers work only on DVD


You might have connected your TV/Stereo Receiver up to the wrong audio outputs of the DVD player. Make sure you are coming out of the FRONT left/right audio outputs and not the CENTER?REAR left/right audio outputs.

JL 500/1 Problem


You need the old transistor. Knowing it's brown is not enough; you need to know its resistance value. It sounds like the resistor you replaced with has too low a resistance value, causing the "cuts" in sound. Find the old resistor and then use this site to find out what you need:

Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..
