There is a "hissing" sound on low volume. Whazzup?

Check the bal./fader on the radio sound setting there could be a misbalance in the settings.

It sounds like somehow the pre-gain is very high while the volume or post-gain is very low. Try turning the volume high on the effects unit and the gain low, and don't have the amp volume too low either.

Take it to a tech. It probably needs an op-amp swap, or has some grounding issues. Check if it's still under warranty, and make your claim.

HI I am having the same problem. tv sound is fine, then fades so that 50 is the only sound volume to hear the show. It happens intermittently. Did you get your's solved? thanks

it is not a problem there are many problem

have you tried to replace your rca cables? sometimes these tend to wearout at the connection point from being pulled off from products they might have been plugged into.also check all your wires for any fraid areas where wire might have been crincked under such items as sofa foot pegs and such. hope this helps

Hello!
Try the audio out. Run the audio to a receiver to see if the audio is there. If it is, then I'd leave it hooked up to the receiver and save yourself some money. If there is not any low level audio out then I'd fix the set. The only Sony set I've ever seen that was not worth fixing was a 32" model from the early 1990's that had bad picture tubes after only 5 years. I am a Sony factory trained tech. Good Luck!

I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.

1) if you are using the PC sound card to record this is where your hiss is coming from. you need to get a recording card that has low noise or some other recording USB input device to get CD quality recordings

OR

2) if you have to use your PC sound card check your PC volume level for line in, don't let it get high or it will distort. you will have to experiment with the MD4 levels and PC sound card level to find a good middle ground with low hiss and no distortion
and a singer that sings away from the mic to reduce distortion.
