My sansui tv makes a loud high pitch noise. I have had it 3 years, it is a a riging noise, and hard to hear the tv shows. what do i do?


ever since for ever, ive always heard a loudish high pitched ring from analog tv's. e.g. i would know a tv was on in another room even if it was muted. ive told other people about it but they dont seem to hear what i hear. so im gonna geuss either

a. analog tv's all make that noise to a verying degree but most people just dont notice it or subconciously cancle it out as normal.

b. its a kind of hyper sensitivity to high pitched noise, in essence, tinitus.

on a final note, its not medical as i always pass my hearing tests. but to answer your question, either buy a digital tv or turn up the volume.

When my rca 36F530 tv is plugged in it makes a high pitched buzzing noise picture does not come on


There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

Trouble turning on tv. High pitched noise/click.


The mainboard might have some loose components, or cold solder , or may be the filter capacitors are becoming faulty. Yes it is worth repairing, bring it to the repair shop. Cheers.
