If the noise starts out fairly loud and decreases or dissapears after a warm up period this is probably the cap problem,which has a detailed solution posted on Fixya.If you replace the 2 caps ,while you are in there I suggest replacing the 3rd 1000 microfarad cap that is very near the 2 10 volt units which are definately bad ones.The repair posting is very good,and if you or a friend can solder it is easy to do.The instructions are really very good.

Vizio L32 Issue: Vizio replaced our 9 month old 32" last week due to a 'failed' repair for an annoying humming. The new tv has the same annoying humming. What should I do? I really don't want another one...


It is still under warranty then you could ask for your money back as replacing it has made no difference.

You will have to search the internet for more advice on this.

High pitched noise on Polaroid HDTV


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.

BROKEN TV


Polaroid has a 1 year manufacturers in-home warranty on 32+ inch TV's. Contact them and they should send someone to fix the TV for you.

Since it is still under warranty make it Polaroids "problem"

hope that helps!

37 inch LCD TV


These Polaroid LCD sets all fail like this. Bad power supplies. Call the warranty number and demand to have the main module replaced even if it is out of warranty.
