My lg tv a 42LK520 42 inch tv that has backlighting and sound but no picture not even menus. some places said that some bad caps or fuses might be the problem. but the fuses seem fine when i mesured and the caps dont seem poped or damaged but i have no way to measure them. the tv was sitting in storage for a few months. it was fine before and then afterwards it started haveing problems. some places said it might be the tcon board or the lcd panel. if its the board i can repleace it but i dont wanna do if the pannel itself is out. any help would be appricated i have some tools and knowhow just not sure where to check.
