Question about RCA 32F531T 32" TV

1 Answer

Loud sound, No TV Picture

We turned on the TV and the picture did not turn on but there is a loud, high pitched type continuous type buzzing noise. We're not sure if this is the specific TV model -- ours is an RCA TruFlat GuidePlus Gemstar. We purchased it in the fall of 2005. We have DirectTV and disconnected from the system and the noise is still there. When we plug & unplug the system the noise is continuous

TV making loud buzzing sound


More sets than you might imagine have this kind of problem---I a regular TV it is usually a transformer that is vibrating hard enough to make the sound---the higher pitched sound is just that--a sound.

If this is a direct view(means not a flatscreen and has a Glass Picture tube it will be either the high voltage transformer or one of several smaller transformers.

This can usually be fixed---seen a few so loud the cats in the house run away.

Let me know model number of set for more information.

On chance it has the high voltage transformer I attach a photo of what that looks like.

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 noise and no picture ON DLP model HLR5668WX/XAA


If it is a high pitched whine or a grinding sound it is a bad color wheel.

Not real difficult to determine and replace.

Let me know if I can assist you.

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.

Loud buzzing noise when turning on


It sounds like a bad internal connection or a component failing. If the picture still is very good take it to a known good repair shop.

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."
