High pitch buzzing and no picture

Our TV turned itself off and started emiting a high pitched buzzing noise. The only way to stop the noise was to unplug the TV. And now every time the TV is plugged in we still can't turn the TV on. What can we do?

Re: High pitch buzzing and no picture

Your power supply, I mean the internal power suppy could be faulty, if you know how to deal with it, check it for abnormal oscillation, or get some help from someone who knows how to repair it.

A piercing high pitched buzzing noise when on. The sound volumne does not affect the buzzing. Always very loud.

You didn't post a model number but if this is a CRT TV (non-flat screen) the noise may be coming from the high voltage circuit and may be a warning sign of failure in the near future.

TV making high pitch noise, stop working.

It must be the horizontal output transistor, it maybe short circuited. A short in flyback.

High pitched sound

you can fix this if you are very careful. it is call a high voltage leak. inside of the tv, close to where the power comes in will be what is called a high voltage transformer. if you are electrically inclined, unplug the tv, take the back off and then hook the power line up and turn the tv on. with the lights off in the room and a flashlight handy, look at where the sound is coming from. locate where the sound is coming from and look very carefully(very carefull not to touch with your hands or head to any part) for a white-ish blue arc of electricity. if you can see this then that is where the problem is. to fix it you will need to put something in between the two places that it is arcing from. a piece of plastic or silicon putty or anything non-conductive will work. again, be very careful or you might get the dogsnot shocked out you.

Power light comes on, followed by a high pitched whine

Hi, If after trying the TV again later and problem persist, repairs are in order. A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube. Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry. Good luck and kind regards.

18 Mo old Samsung CXM2785TP made high pitched noise and lost power

The high pitch sound could have been the flyback transformer. check the horzontal output transsitor if is gone the tranfomer is sure to be gone . Tranformers are varying in price are the transistors can also vary you could be looking at around 150.00 plus labour.

High-pitched noise when I turn on the tv

No I think your problem is the horizontal output transistor blew out an that was a result of the flyback transformer going out or blowing up.. Good Luck TO you.
