Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

Humming sound My problem is that when you turn the TV on there is a loud humming noise. I have had the cable company come out and there is nothing wrong with the line. the sound is coming from the TV.I have had the tv serviced and they ar indicating that its some type of sound board that can only be purchased overseas and that is going to take about 8-12 weeks maybe longer because this part is only made once a year...... Please assist

    I have a humming-like sound very high pitched almost so that it is uncomfortable, maybe painful, but, after about 2 mins or so it fades away and is fine. It happens almost every time I turn it on. Rear RCA Ports (red, white, green, blue, red with yellow) for sound/s-video do not function. I get some sound or weird sound, but, no real picture, unless flippy grey images is a good screen for XBOX gaming. I'm assuming the card to the ports is bad. Can I replace it myself or even the sound?

OVERSEA'S ...thats just wrong... rca parts are availble all over the place. does the sound eminate from the speakers? DOES it go away when you turn it down.. if so two possible outcomes. speakers or something called ssb board which is the main signal or main board in this set. but the audio amp and all audio cuircits are on this board. this board is however technician replaceable only.. authorized technicians have a special computer interface used to transfer settings from old to new board. there are cases where if the humming is coming from the back which might mean flyback or a coil vibrating. is it a lound hum or whine? o buy the way i get most of my rca parts at the shop from union electronics.

Benwin 5.1 surround sound system Humming loudly without anything pluged into it!!!


It is sad your having a problem with your
Benwin 5.1 surround sound system
If humming can be heard on all speakers, then it could probably

be on the power supply.


If it is only on the main SUB unit, then it could be the amp itself.

But check for power supply capacitors that supplies voltages to the

amps.Check for amp output DC voltages too.

There is a coil in the set with a magnet glued to it, called the horizontal linearity coil. Sometimes the coil "sings", making a squeeling sound. I have seen this many times, and there really isnt anything actually electrically wrong with the set. To stop the squeeling the coil should be replaced.
