The buzzing sound could be from what they call a Ground Loop.
This is cause by plugging in Hi Fi and computer devices etc. into different mains power sockets.
The way around this is to use a power board and connect all your devices into the power board and plug the power board into a single power socket.

Rca model rtd3266 won't produce aux audio through the tv even though we have hooked up the red and white cables. It only playes the surround sound when you watch the dvd.


I believe you have misunderstood something. The audio output from your TV is stereo. Your RCA system produces surround output from your TVs stereo input.

I just bought a Blue Ray player but my surround sound has a dvd player built in and only one input which I have my new Sharp TV plugged into. How can I hook up my Blue Ray . I have the HDMI cables


Depending on if your surround system has a hdmi input or not. if it does you can connect the blu-ray player to it. If it doesn't have an hdmi input you will have to run the hdmi cable from the blu-ray to the tv then run a set of rca cables (red and white plugs) from the tv audio out to the surround systems' audio input jacks to get sound through the surround system. Most surround systems don't have an auxiliary input for another video device.

No surround sound on normal tv just dvds


Do you have a cable box or satellite box? If you do, try hooking up your TV sound through the box. Look for audio out in the back of box (white/red RCA Jacks). Hook RCA cable from cable box to surround amp. Even if the audio out jacks are being used already, you can use Y connectors to hook up the surround amp to the box.
Hope this works for you!

My Panasonic SC-PT760 system just doesn't sound right. It sounds perfect with every function besides the AUX. Music and DVD's sound how I think a surround sound system should work but my LG HDTV sounds...


it definetly sounds like their is a set-up issue or a grounding issue , refer to your user manual for reference to check your wires ,also bad buzzing sound also comes from cheap rca cables that you might be using for components to your system ,also sometimes the end jacks of the rca get worn out and don,t provide good conductivity , auxillary inputs should be used for playstations or x boxes and not for anything else , hopefully this was helpful, sincerely Glenn

A loud buzz sound when the surround sound unit is powered on.


There is most likely a voltage regulation fault, or some filter capacitors that are going defective. It would be best to have this serviced before the parts fail completely and cause some damage.
