Polaroid TLU 03711C - HD LCD flatscreen TV 37

I have got a Polaroid TLU 03711C - HD LCD flatscreen TV 37".

every time i turn the tv on, its make a high pitch buzzing sound, this will continue for up to half hour slowly fading out. if i turn my tv off, then back on this will happen again, every time.

when i have turned the tv on and its is buzzing if u turn down the volume, the buzzing will remian, however if u put the tv on mute the buzzing will dissapear.

i think this mite be related to my xbox 360, altho if nothing is plugged into the tv this will still happen.

I think it mite be related because if u have left the tv on for a hour and the buzzing has died down, then u put the tv onto HDMI1 (xbox channel) u can still hear the buzzing.

Also if i try and turn my tv onto channel HDMI1 (xbox) within the first minute of turning it on the tv crashes and i have to turn it off at the plug.

I have bin told i need a replacement 'main board' is this the case?

and what is the actual problem? and is it related to xbox? (altho when i didnt have xbox plugged in, problem persisted!)

thanks

    I have the same exact problem! also sometimes it wont turn on unless i unplug and retry

    There is a high pitch beeping / buzzing tone which eventually fades away after about 5 minutes. The sound stops when the TV is muted but it doesn't make it go away, it simply comes back when the sound is turned back on. I found a quick solution is to turn the sound up on the TV which sort of overrides the tone, but this isn't really a work around.


    I have read that it's something to do with a capacitor which has blown, however I have no ideahow to replace such an item so I will be calling local TV repair firms.

Buzzing sound after only 2-1/2 years of service


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


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.
