Tv make a buzzing sound, when turning the televiion volume up or down the buzzing tay exactly the same.


Sometimes this can occur through other equipment connected to the TV (e.g. link to home theatre system / stereo etcetera. I get this sometimes if I have left my laptop connected to my stereo system, which my TV is also connected to, even if the stereo is not turned on.
Unplug all external devices one by one to see if this solves the problem.

Buzzing sound


Hello, This is a problem with the switching transformer or the ballast used to fire the backlight. You will have to replace the ballast and or the switching transformer soon. In order to replace these items, I would suggest taking it to a qualified TV technician for servicing. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

No picture


I had a similar problem and got a TV repair man to fix it for real cheap. The whole fixing took less then 30 min and he goes to your house to fix the TV. He fixed it for an excellent price that left us astonished. He lives in NY. Email me if anyone needs his contact information. You wont be disappointed.

My polaroid has sound and picture problems


This is a well-known problem with many Polaroid FP displays. Eventually, the picture will simply go black, rendering the TV useless. The solution is a new control board, ~$400.
