SOURCE: high pitched noise from inside the TV when picture comes on

Hello randapaint,

This might be from the IHVT (Integrated High Voltage Transformer), or more specifically a short in the IHVT causing it to arc, producing the high pitched whine, you are hearing. Take the back off of the TV and try to detect where the sound is coming from, more then likely you will notice it coming from the section that contains a large component with a large red cable coming from it, to the top of the CRT (picture tube). Replace the IHVT (with the exact same model) if it is bad.

I hope this helps,

Thank you,

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.

Rca 27410tyx1 will not shut off


Sounds like trouble in the standby/power up circuit. have you tried unplugging the TV for a half hour and seeing what happens? It might start up but I think this problem won't go away. If you heard a high pitched buzzing it sounds like a problem in the high voltage not letting the start up circuit work. threy are related. The start up circuit waits for the high voltage to stablize and then switches it on.

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."
