Question about RCA HD52W59 HDTV Projection Television

1 Answer

TV is making a loud high-pitched noise that goes on for about 2 - 3 minutes. Its coming from the lower back part of the TV not through the speakers. Sometimes the noise pulsates and makes the picture jump a little. This will happen once every 2 hours.

High pitched noise coming from back of Viore LC32VH56A. Not speaker related.


A refurbished set!

Its a coil or transformer that is not tightly mounted or is vibrating hard enough to make the sound, If this is a refurbished set that is why it was returned and exchanged-----

Two ways to fix---locate which board is bad and correct the problem with Hot glue on the individual part making the noise OR just replace that board.

Samsung dlp tv HLP5663W makes loud noise


Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

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.

They are makeing a constant sharp noise a loud high pitched hum if you will


Right-click on the speaker icon in the lower right of your screen and choose Open Volume Control and check all volume levels (make sure they are not set to high). If this doesnt work then when you right-click, choose Adjust Audio Properties and search around for volume controls (maybe try the Speaker Volume button).

Weird noise over everything


According to the Samsung website: "The high pitched sound you hear is probably coming from the flyback transformer. The flyback transformer converts the relatively low voltage electricity that comes from the outlet in your home to the high voltage electricity needed to drive the cathode ray tube in your TV. It is not unusual for a flyback transformer to buzz softly when it operates. However, if the sound is loud and high pitched, it probably means the transformer is failing. To eliminate the sound, you will have to get your TV serviced."

Occasional 'whistling/whining' from back of TV


I wonder if there is enough air circulating around your equipment?? My DVD recorder makes a sound unless I open the doors on the cabinet that contains all of my equipment. The cable company says it is a fan to cool down the units.
