Re: LG 42LK450-UB No pic/No sound

Reviving this old thread as I'm having the same issue with the same model. LG 42LK450 - standby light comes on red and turns blue when power is turned on but no picture. Voltages on the DC side of the power board are almost identical to the OP except I only get .03v on Inv On/Off when powered on. Main boards for this model seem to be becoming extinct, and the few that I've found run about $100 and I just don't know if the TV is worth that.
