A noise started last night from the back of the panel, sounds like a loud cricket chirping. doesn't affect the performance but is very annoying due to the how loud the noise is. Any ideas what this is? A fan of some sort? No chirping sound if the screen is a solid colour like with a screen saver on.
I have a panasonic 42" Plasma. It makes a "chirping" noise. The noise is coming from the right side of the Rear of the television, when looking at the rear of the TV. Any help would be greatly appreciated.
I have had the TV since Nov. '08, so about 5 months.
Thanks!
The noise is coming from one of the plasma driver boards. There are 2 inside the set. These are essentially power supplies for the plasma itself and contain many capacitors. The noise you hear is some oscillation inside a cap or two. This is an indication that one or more components have drifted from their rated value. While the set will continue to work for a while, that board should be replaced. If the board fails, 1/2 of the picture will be blank or the set will not start at all. Call around to get the cost of that board. Please note that continued use of the set WILL NOT cause any harm. This is an annoyance only at this point.

Check the fan make sure there is no dust. Check the power supply make sure its free of dust before you draw any more worries about it do those two things, Vote positive when voting on this solution and it was my pleasure to be a assitance to you.

Check on the back there should be vents in there should be a fan, if it gets to complicated you would want to have a tech come out a clean it professionally. :)
