The buzz is very likely from the power supply. This may be occurring due to a shorted component else where in the units circuitry. The supply has a protect mode when it is over loaded and its operating frequency drops into the audible range when in this state. You will need a technician to diagnose this and give you an estimate, unless it is under warranty or a service plan.

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

Sounds like a coil is vibrating or a component is bad causing the transformer to whine. Could possibly just need soldering.

Alot of loud feedback through speakers, a loud buzzing noise


What sources make it happen or which do not? All buzzing = something in the amplifier end. is it from all speakers or just one?
One external source= RCA cables not grounded. Reconnect them tightly with a twisting motion to wipe off oxidation.

Rca l26wd14 buzzing


Hi!

I have seen this before in a lcd tv I worked on! My problem was some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). But also check the signal board (rca s-video etc... inputs). My thought in this was a bad cap was producing a harmonic, causing the speakers to squeal! Good luck, I hope this is helpful!

Buzzing after 1 hour


Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?
