What is the whistling noise coming from my TV?
The whistling noise coming from your TV is usually a high-pitched sound that can be quite annoying. It’s often caused by electromagnetic interference (EMI) or radio-frequency interference (RFI) from other electronic devices in your home. This interference can be picked up by your TV’s internal components, resulting in the whistling noise.
In some cases, the whistling noise can also be caused by a malfunctioning component within the TV itself, such as a faulty capacitor or inductor. If you suspect that the noise is coming from within the TV, it’s best to contact a professional repair technician to diagnose and fix the issue.
How do I identify the source of the whistling noise?
To identify the source of the whistling noise, try moving your TV to a different location or switching off other electronic devices in the room.
