Question about Polaroid FLM-3732 Television
When the TV is turned on a high pitch noise is heard. After about 3 minutes it stops. If you turn on the direct TV receiver at the same time the noise is louder especially if it is on an HD channel. Sometimes it will even effect the picture if you turn them on at the same time. The TV is about 2 years old. The direct TV people were out and said it was not their receiver causing the problem. High pitched noise persists for several minutes after turning on the TV and then it goes away. The volume the signal from our cable box doesn't work anymore. I plugged the cable directly into the TV, and we have to do a channel search every time after the TV has been off for a while.
I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.
You can read a similar guide here http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen but I will shortly be uploading a guide on the buzzing problem!

SOURCE: High pitched noise
The power supply is starting to fail on your LCD. The noise you hear is because the circuit is trying to provide the proper power to the rest of the circuitry and is forcing itself.
The noise does increase if you tune to an HD channel because of more demand for power for a brighter picture.
Let me know if you need further assistance.
