likely a coil or small transformer in the set is vibrating hard enough to make it squeel, it would have to be located with back off by listening to see where it comes from.cure would be to replace the entire board it is on or hot glue the part that is causing this to dampen the sound.If it is coming from the front screen unit that is a more serious issue.

if you have the right tools then you can do it, make sure unplug the tv unit first while replacing the board. then mark or put a label to the connector that you were disconnect not to interchange that can cause of damage to the other board.

You can get rid of it by pushing the "Menu" button on the remote, then selecting "Setup" on the screen, then scrolling down and pushing the "CC" option. You'll see a list of controls, the top of which reads "Mode." Highlight it and cycle through the options until you come to "Off." Select it and exit the menu with the "Exit" button. The black box should disappear. Adjust the SAP setting if the sound isn't coming in, or is coming in oddly. The SAP button should be in the top right-hand corner of the remote.

You might also check the "Mute" button to see if it is activated, or simply adjust the volume. This will help.
