Question about LG 50PC3D 50 in. Plasma Television
I would first check for swollen capacitors on the power supply board. This model has about 9 under rated capacitors that usually go bad. The original caps are 3300 uF rated at 10 Vdc., and they should be replaced with 3300 uF capacitors rated at 16 Volts DC, 105 degree types. A failure on this board could also affect the other boards in the set so correcting this problem may not remove the symptoms.
