Continous Buzz/Pulse from speakers No other sounds come out
We have owned our rca system for 6 years. This year the sound stopped coming out of the speakers. It was replaced by the same buzzing/pulse sound like when you run a test of the speakers to hear if they are connected or not. No matter which DSP button we press the same sound comes out.
At first we thought by just unplugging the system for a while would just fix it right up, but that didn't work. All the speakers are connected because we can still hear the buzz/pulse noise.
Thats all I can say about it. we dont know what to do. please, any help would be great

Re: Continous Buzz/Pulse from speakers No other sounds...
Sounds like you have an open filter capacitor. Your gonna need to look at the b+ and figure out what cap is bad. A circuit diagram would assist you in this repair. If you have no experience with electronic repairs then your gonna need a pro to assist you with this as there are no user replaceable parts inside this unit. Sorry Man. Good Luck

Sometimes, an electronic pulse can cause this protect mode. this can come from an electrical storm or, bad circuitry in the home. Unfortunately, you may have to repackage and send back to the manufacture for repair.
Hello, you can verify that your receiver is working or not. When you are playing a dvd unplug the audio RCA plugs (red and white) from the back of the Sony dvd player. Touch the tips of each of the RCA plugs with your fingertip. You will hear a buzz sound coming from the speaker associated with the plug if the receiver is working\ i.e. touch the red RCA plug tip and the right speaker will hum...touch the white tip and the left speaker will hum or buzz. This will not hurt your system or speaker. If you do not hear the hum turn the volume to 3 or so and wet your fingertip and tap the tip of the RCA connectors. You will hear "pops" coming from the respected channel. I believe your cd\dvd is at fault. Good Luck!
It sounds like a capacitor in the power supply is just about to die. With the power disconnected have a look at the large tin can looking gizmos near the power transformer. There could be a couple of them. Leave the unit switched off for a while before going near them they could still pack a splat. Replace them with the same value and make sure they're connected the right way and it should solve your problem.
Whilst in there have a good look for any other smaller capacitors which look as if they're getting rounded at the top. Replace them too.
Either that or dig deep and buy a new one.
