High pitched noise on Polaroid HDTV

I read your answer about the reason for the high pitched noise and picture interference on the Polaroid HDTVs. I just started experiencing the problem myself. After reading your solution, I just have to ask what do I do now?

What can I do to fix this? Call Polaroid? Right now, I've muted the audio, but that is just a temporary fix.

Thanks for your help!

It appears like your power supply is not filtering the voltage properly and that is why you are hearing that high pitched noise. If your LCD is less then a year old, you can call Polaroid to have it repair under warranty.
If more then a year old, check the info from this link to replace the capacitors.

Let me know if you need further assistance.

No color only black and white picture and high pitch noise


high pitch noise is most likely the color wheel; pt# for L3 chassis:BP96-00674A pt# for L6 chassis: BP96-01103A
This could also be part of your lack of color, otherwise may also need MAIN or VIDEO PCB

When turned on picture fluctuates and emits hig


The high pitched noise is coming from the Tcon board. It is not properly decoding the signal coming form the main board correctly. The only way to fix it is to replace the Tcon board. You might have a hard time coming across the part because Olevia has since gone out of business. Also, usually Tcon boards are not available sepertaly and most manufactures make you purchase the whole LCD panel of which the Tcon is included.

High pitch noise coming from the tv.


I suspect you have a bad set of capacitors in the control module. This problem usually starts out as a high pitched noise but can lead to the TV not turning on. Please see the link below, posted by StivO. It gives step by step instructions on how to replace the capacitors. This is a very inexpensive fix.

High pitched noise


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!

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.

TV making high pitch sound


Hi, There are usually 1 or 2 fans inside the TV's. Could be worn bearings, or fan blade interference. Sorry, without my electric ear working, I can only guess.
