Re: SanyoDS25390 Tv good picture buzzing noise

What are you using as a source? If its a cable/satallite box, double check that first. If its a video input or a scart input, swap out the cables. If it still there you could have an input problem or a filter capacitor going bad. Does the hum get louder with sound? If it does it is an input source and or cables. Good luck Ps please dont forget to rate this thread.

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.

I do not have a credit card. I have connected my wireless headset to the TVs audio out on the back and it works great. My problem is I can not mute the TV speakers, so the sound is comming from both...

Try just turning the volume down on the TV. The audio power to the red/white output jacks should be the same at any TV volume since it is expecting you to control the volume with an audio receiver or other amplifier.

Good luck.

I have a samsung dlp model hlr4667wax, when first turned on it makes a whistling noise then a buzzing noise any suggestions?

It could be you color wheel try to go bad, however when it does you will lose the picture. If you can repair or fix a computer you can change your color wheel if it goes. Cost Appox $100 you can search by your TV model #

Good Luck!

KV-32FS120 makes a loud noise and green tint when turned on

Loud noise is possibly made by Degausing Coil to demagnetize picture tube and its normal.
Green tint shows picture tube is bit weak in electron emission due to its age and takes time to present good white balance result (good colors)

Color switches to b/w, then a click, then color, then b/w, click, etc.

Good day.

I think your problem is with the crt circuit. It is the one on the rear of your picture tube. Some loose connections may occured in there. Also, check if the flyback is arching. Sometimes, the voltage on the flybach itself causes this.

Buzzing Noise and TV picture is yellow

Andy, I'm thinking the buzz is from the deflection coil (yoke) on the neck of the tube or the power supply. Probably not the high voltage as you can hear the "buzz". If it's really that annoying, you can take a length of rubber tubing (no metal) and listen to the buzz coming from the chassis kind of like a stethoscope. STAY AWAY FROM THE HIGH VOLTAGE, please. The yellow picture sounds like a blue chroma failure. A tube can be rejuvinated if need be but that's a job for a pro. Hope this helps.
