These units are known for having bad solder connections develop over time. Would have to check bottom of main board for bad connections especially around amp ic's and voltage regulators.

SOURCE: Sound not coming from left side surround sound speaker or my right side front speaker

it is highly likely that you're TV is outputting mono sound, hence the left channel only. check your physical connections to the TV and the balance / channel volume on the television as well.

SOURCE: Pioneer VSX-505S Subwoofer Installation

That type of subwoofer is not used with this receiver. This receiver actually outputs no power for a subwoofer, therefore only needs a plain ol' rca signal wire. This is due to the fact that you need a powered sub... one that you plug in to the wall and it has its own built in amp. you simply run an rca from yyour 505s to that sub.

SOURCE: No Soound on Subwoofer from Yamaha RX-V363

I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

SOURCE: Pioneer VSX 818V No Sound

First thing to check is the Speaker Select Switch. It will say, "A" "AB" or "Both" it will be displayed on the LCD screen as well. Second if that's ok, Check the "Direct" switch. If it's on, turn it off. Generally if it's on, you will see a blue light if it's on (most receiver's)

If you still have No audio, hook up your DVD to the "Direct" input and turn "Direct" on. If you have audio then. The DSP chip is probably bad and you should take it to a shop and have them bench it first to confirm. Hope this helps

My technics sh-eh780 stereo seems to work but the sound is very dull in sound


Unless there's an issue with internal components of the amplifier or speakers, a common cause of this is reversed speaker polarity.

The wires between the + and - terminals of the speakers MUST connect to the same + and - terminals on the back of the stereo amplifier. The speaker wires that came with the stereo are color coded to help prevent mis-wiring. If you did not pay attention to this or used different wires for any reason, you need to ensure that the wires between the each of the speaker's 4 terminals connect to the correct group and + / - terminals on the amp.

See page 6 of the manual here: https://support.panasonic.co.nz/docstore/SC-EH780%20Operating%20Instructions.pdf

Make sure that the surround and center speakers are connected correctly, too.

Good luck!

If bumps affect the noise then you should be looking at loose wires and connections for the speakers and at the back of the system. Look for a bad earth or the earth wire connected up to something that is not really a good earth

What would cause the driver side front door speaker and the passenger side rear deck speakers not to work. When if fade the sound all the way to the front with no sound in rear and with the balance turned...


Check the speakers if they work. Connect the speaker terminals using a short wire to a 1.5 volt battery (AA or any dry cell batter) and listen if there's a thumping sound when the wires are connected to the battery terminals. If there's no sound, your speakers are busted. If there's a sound, check if the wires are okay. Use the same method with the battery with the wires from the back of your stereo. Make a small cut on the wire and attach the short wires you used earlier.

I need a radio wiring diagram for a Holden Commodore LS 1991


Regardless of colour coding, please follow the following instructions (require multimeter):


Note: Attach multimeter earth wire (black) to the vehicle body. Convenient places may be the metal ignition barrel, the vehicle's car arial plug, cigarette socket body etc.


1) Testing for voltage with key out of the ignition, locate the permanent positive wire. This will wire into the yellow wire on your new stereo. The yellow wire circuit powers the stereo's memory.


2) Testing for voltage again. This time you are testing for a wire which only offers power with the ignition turned on. This one will wire into the red wire on your new stereo, and will power the unit only with the ignition on.


3) Now you know which your vehicle's positive wires are you can now test for an earth wire. Switch the multimeter to the resistance setting. There is one setting which will allow a buzzer to sound once you find continuity. With the ignition off test each wire until you get a buzz and a low resistance reading. This should be your earth wire. Double check this with the ignition in the on position. It should remain the same. If it changes to a positive with the ignition on and with the vehicle's lights switched on, then this is the dimmer feed for the stereo's screen. If you unintentionally found the dimmer feed, then you can ignore this wire, and search again for a wire which only offers an earth.


Now you have your power and earth wires located and can wire these into your stereo before continuing.


4) Next you need to use the stereo's balance and fade controls to allow only one speaker output to work from the stereo. So let's start with Left Front speaker output only. turn the stereo volume to mid way so that you can hear when you have connected to the right speaker. bare the remaining wires on the car side and test combinations of the remaining wires until you find the front left speaker of the car. Wire your stereo's wires once you find the correct connections.


5) Repeat the above steps with all remaining wires, remembering to adjust your stereo's balance and fade controls to only allow one speaker output at a time, to ensure the only one possible channel to work and help you identify which of the car's wires power the speaker you have selected.


Before re-assembly of the dash panel, check that your stereo and all functions work properly, being sure to use your fade and balance controls again to test all speakers individually.


If you want to be extra careful and wire the vehicle's speakers positive and negative, according to your stereo's outputs, not that this makes much difference on standard stereo arrangements, then follow this next step:


Make sure you can see the speakers themselves and connect a 1.5 volt AA or AAA battery to the speaker wires. If the speaker's cone pushes forwards, then the wire you connected to the battery's + terminal is indeed the positive wire and should be wired as such. If the speaker does the reverse, then you have the wires the wrong way around. Do not repeat this test for extended periods as damage may be caused to the speaker circuit.


Tip: Always solder all connections and insulate well from each other. Stereo connections can corrode over time and are prone to movement behind the dash. Poor connections may cause faults and low quality sound.

Low Volume from right speaker of entertainment center - turntable only


Hi There thanks for your very good desctiption of the problem it really helps to have a lot of detail...

There are Mono and stereo types of stylis cartridges and it sounds like you have a mono equipped into a stereo amplifier..

If there are 4 small coloured wires visible under the stylis then
its a stereo stylis and should work, have a close look and maybe one of the small wires has dropped of the small pins on the back opf the stylis cartridge.

If there only two wires visible then its a mono cartridge and this is why you only have sound from one channel..

So answer is wires dropped of the stylis.
or
Wrong type of stylis cartridge.
or
if there are four wires and thay all look connected then perhaps the stylis is faulty and you need to replace it...

It could be that the wires in the harness that go to speaker from stereo are not connecting to the leads on the stereo. If this is the case the wires to speakers are not connecting, but the wires from the power source are still good. Try taking the harness out of the back of the stereo that connects all the wires to the leads. Hopefully your wiring is labeled from the factory. If it is it might say "Left front speaker". Isolate this wire and wiggle it inside the harness back and forth. If it moves even a 1/16 of an inch it may be that the leads are not connecting. You can try jerryrigging it by shoving something in their in hopes that it will hold it in place. You may need to replace the harness.
