Emerson research model #iP100 speakers no longer work. Right before they stopped working if we "tilted" the unit, the light would come on briefly and then go out. Any suggestions? Catherine

I have a pioneer VSX-1016V receiver and after a while the right back surround speaker stops working . I have also noticed that the cooling fan inside does not start either and the unit gets hot.


Sounds like its power amplifier circuit has the fault. Contact any service technician. Make sure that the fan works properly; otherwise further damage will surely occur due to overheating. The circuit seems to be much complicated. Contact any experienced service technician. The work cannot be performed by a normal user, I should say.

Pioneer VSX-21 Elite: Issue: after playing music softly for about 1 minute the machine goes into "overload" mode. Unplugging will reset this. Keeps going into this overload mode, acts like...


Check to see if the unit is getting unusually hot.
If it is, check the impedance of the speakers and speaker wires to make sure they aren't shorted, or close to shorted (ie - partially blown speaker).
Try running the unit with the speakers detatched to see if it still happens.
If the unit gets hot with no speakers and goes into overload, then we need to start checking the components inside.
Look for electrolytic capacitors that are bulged at the top, or that have discolored the circuit board at their base (leaking).
Any caps doing this will need to be replaced, and will likely solve the issue.
If there aren't any, or if that doesn't solve the issue, start checking the transistors at the output.
Look to see if there is a DC voltage riding on them, and make sure they aren't shorted out.
If the power amp is a hybrid chip, see if you can find one cheap and replace it if you can't see anything else wrong, or if one of the hybrids is overheating a lot.

My tuner will not work! I've had this unit for 4 years & it's always worked perfectly. Then yesterday, the tuner stopped working. "Tuning" flashes on-screen intermittently & no...


1. Verify the source of the signal - Look for any antennas that may have been hooked up, and verify connection has not been moved or removed.
2. Test with a different output by plugging in some headphones, and recheck the volume through the headphones.
3. Check that the A/B switch for the speakers has not been moved, and that they are switched to the correct speakers.
4. Try AM and FM for any signals both with speakers and then headphones.

Good luck!

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

Speakers stop working


This is either a loose connection internally or a dirty control such as the volume control. Both of these will require a trip to the shop

My right speaker is no longer working. I have an


This could be as simple as a bad connection or more derastic like defective output transistors. Without looking at the unit and taking measuerments, it is impossible to say. As silly as this sounds, make sure you didn't hit the balance control all the way to the left. If not that, then I would suggest getting a detailed repair estimate from a servicer. Report the results of that estimate here and we should be able to walk you through the actual repair.

I have wireless speakers and the transmitter stopped working. Nothing happens when you plug it in--??? It's only a month old. AW872


Hi I also post in here , so that you can let me know how it goes.

Try unplugging the transmitter from power adapter, if it also has batteries remove them. Also unplug transmitter audio cable.

Then remove batteries/unplug adapters from speakers.

Wait few minutes and reconnect the system.

This is a proper hard reset, and can fix minor problems.

If when you re connect the transmitter does not glow, or you do not have sound on one or both channels then there is a fault.

Check the transmitter audio cable, a short in there can cause troubles.

If you find no problems , then unit is defective, as it is under warranty contact Acoustic Research to validate the warranty here and get the transmitter or the whole set replaced.

Denon AVR 883 Audio glitch


More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.
