Picture ok but loss of sound with high pitched buzz

Periodically after the television has been on for about 8 hrs the picture continues as normal but the sound goes and a high pitched buzz comes on. The only way we can get rid of the buzz is by turning the television off and putting it back on. any answers please help!

A loud buzzing is coming from the back of my sanyo ds 25390 tv. picture and regular sound is fine


If it is a high pitched whine or buzz it is likely a transformer vibrating so hard it is making the noise.

There are ways to try to deal with this issue but the set has to be opened and probed to locate where it is coming from--


for example with back off and set on a plastic rod can be used to touch areas and exert slight pressure until the sound changes or goes away--then either replace the part or I have used hot glue etc to stop it.

You first have to locate the source of the issue:

find where it is coming from.

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

No picture and blinking light consistently


Do you hear clicking or like wanting to turn on? it could be the ballast which is the board that powers the lamp .Do you hear buzzing ,whirling or like a high pitch sound? If you do it could be an issue with the color wheel.If you don't hear any of that and tv is between 1-2 yrs then most likely it's the lamp that needs to be replaced.Your Original lamp is Osram and last 4000-5000 hrs, get the Philips which will last 2-4 yrs 6000-8000 hrs.God bless you!

High pitch screech w/no signal


is this a picture tube type of tv? big in back? If so, it could be the tube/circuit short.

If it flatpanel, it could be a bad capacitor in the DM or "Y" board or even possibly faulty power supply. Further testing will be necessary

RCA D52W19B makes high pitched buzz when on


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

High Pitched Noise


most high pitch noise comes from the anode conection on the picture tube thats connected to the flyback anode cap thats mean there is a high voltage leak,to stop the noise you can discharge the high voltage take off the cap and clean with alcohol.if the noise continue.you will have to put some red or clear silicone both the cap and tube stick together leave to dry for about 2 to 4 hrs.this will eliminate the leaking.good luck.
