Sounds like the back light is out, and the unit needs servicing. You can check this by shining a flashlight close to the surface, and if some image is seen, the the back light is the cause. Else the LCD driver is gone.

try to check the amplifier section of your television.or replace the whole board of an amplifier.or check the speaker.replace if busted.

my polaroid model #3200  does'nt come on!  the light goes from red to blue and nothing,the picture stays black with no flashing or flickering

this sound like panel or inverters that drive the lamps ( fluorescent lamps that are not replacable they are part of the panel).

If you have no power light at all on the front of your tv. Check the fuse by the power coard.

If you have a red light only and have the dark power board with black heat sinks. check the fuse in the center of the power board.

if the light turns blue when you hit the power button but no picture and have the dark power board replace the 2- 1000 mfd 10 volts caps with 2- 1000 mfd 16 volt caps at 105 deg.
