The 7 Best Technologies Of The Colour Television

Why is my subwoofer hum when any device connected to your TV is connected to my receiver?

I STR-DG500 6.1 channel Receiver Sony, Cerwin-Vega an active subwoofer and a Sony 55 "1080p Projection TV's SXRD. When you connect a RCA cable (digital or analog connection) for the STR-DG500, that is connected to a component that has any connection whatsoever to the TV (DVD player via coaxial cable box stereo analog or digital through analog stereo, even my iPod through a docking station, if the video connector is plugged into the TV) I have a horrible humming the subwoofer. If I use an optical connection or disconnect the TV component, the buzz disappears. If I connect an audio device only through a connection No hum. Hum holds regardless of the subwoofer phase, adjustable volume and crossover freq. Any ideas would be appreciated – amplifier and sub-have been both in ensuring service, but the problem persists despite assurances from the local Sony-auth. Shop the problem is, diagnosed and repaired. Thank you.

What is your audience is more likely a problem with your designs. His sub plugged into the same outlet as the rest of your system using a power surge or a conditioner power. If not, you should try to get one. If the submarine is away from the TV to ensure that its roughly the same circuit as the TV. You can also try turning off the circuit and pull the plug and tighten all the screws that connect copper to it, the longer release some. Worst case, you can use ground clearance to buy at any hardware store to remove the soil above or below the TV and it will probably also clean buzz. One warning, if you do that by raising the floor if the shorts device outside the exterior frame to be charged because there is no reason to be fixed so do not touch until you disconnect, the probability of a child it happens, but you can.
