a couple of things could make the tv chassis whistle
1 coud be dry solder joint probably on power capacitors
2 IF your tv has tube the board on the back could be making the noise its to do with the yoke on the way out!

sounds like inverter board. What it sounds like is happing is your LCD is working ut the backligkt board that allows you to see is kicking off. (as you still have sound) Which could be the (most likely) inverter board, or the power supply board. You can take apart and check for voltage at your power supply. The power supply has a pigtail with large white wires and a connector. Power up with the center back cover off and check your voltage at the white connector on the power supply before and after the screen gos out. If there is no large voltage loss it is your inverter board.
You can used boards on e-bay or
