Question about LG 42LC2D 42 in. LCD HDTV
Sounds like you got a bad back light or invertert, Take a flash light to the screen and see if you see a faded or distorted picture if so replace the back light and or
inverter. A local tv repair shop would be ideal if you do not know how to test these things.
Thanks hope this was very helpful to you when you cast your ratings and feedback today.

The most common cause of Failure in this unit is power supply failure caused by failed capacitors. A visual inspection is The easiest way to identify and confirm bad capicitors on the power supply. Such a capacitor will show one or more of these symptoms: 1) Bulging of the vent on the top of the capacitor. (The 'vent' is the impression stamped in the top of the can. The impression forms the seams of the vent. It is designed so that if the capacitor becomes pressurized it will split at the seams relieving the pressure rather than making it explode.) 2) Sitting crooked on the circuit board as the bottom rubber plug is pushed out. 3) Electrolyte (a crusty brown substance) leaked onto the board from the base of the capacitor 4) Venting from the top of the capacitor, visible as rust-like brown deposits, or a visible hole in the vent Once the power supply is repaired or replaced your tv should work normally
