The input signal is missing and the blue screen background comes on the screen. Change the input to some other device which you are sure works and see.

This is definitely a problem with the LCD controller of the tv or the LCD panel itself. However if I were you I would hope that its just the controller(which costs about 50$) and go ahead with the replacement to see if that resolves the problem

This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.

White Westinghouse flat screenTV freezes up and hums.


Sometimes if you just press on your overscan button on the remote and make the picture a little bigger or smaller the humming noise and freezing of the picture will actually stop.

High pitched whine when the motor starts


Had the same problem. It quit within about 5 seconds after turning the TV off. Replaced the color wheel and the whine is gone. The picture also looks brighter, which may be due to dusting the projection lens with lens-cleaning compressed air (from a can). The color wheel was about $100 from Samsung parts and it took less than 3 hours to replace. See http://www.jangro.com/a/2006/07/24/samsung-dlp-replace-color-wheel/ for good info, and be sure to read the cautions.
