Fluctuating high pitched noise when watching TV

We have a Panasonic Viera plasma TV and when watching programmes there is a high pitched noise which comes and goes, seemingly dependent on what is on the screen. Can't determine the pattern. the noise seems to be coming from the top of the TV, on the LHS when looking at it

Turn everything off and disconnect from mains.
Wait a few minutes.
Disconnect HDMI cable.
Turn on TV and DVD.
Connect cable.
If this does not work use a cable of different spec.
I had the same problem and now mine works .
Good luck.

SOURCE: 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.

Panasonic viera making noise from the back even with tv sound off


That is often a capacitor on one of the boards making that sound.  It is actually normal and does not usually mean that there is anything wrong with the TV.  This happens often with computer parts and well, and sometimes gets as bad as a high pitched squeal.

High Pitch Noise on 42" PLasma Gateway TV


how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

Tv making clicking noise while I am watching


Hello everyone,

I bought the model TH-50PX60U June of 2007. I've been hearing the very annoying clicking noise as well.

Since the TV has a one year warranty, I just called Panasonic and they've scheduled a tech to come over and take a look at it three days from now.

I will publish the results on the same page.
