Question about LG 42LG30 42 in. LCD HDTV
Your LCD backlighting system is not functioning.Your LCD main board should detect the problem and would give you and error code.This needs an immediate service.See if the Tv is under warranty then you can return it an get a replacement.It usually the inverter that has the problem but also either one(even just one)baclighting bulb goes off it will shut off all the backlighting bulbs,thus a sound with no picture as a result.
