Model # 42PX4RVC-MC, chassis # RF-052C, dead, plug in, after a few
seconds, the standby led comes on red, @ turn on it turns yellow for a
few seconds, then green for a few seconds, then back to red, & dead.
The B + indicator diodes do as follows: d1003 is always red, d1104 is
bright red @ turn on, d1102, & d1103 are dim @ turn on, & d1101
is bright @ turn on, then slowly dims. Have no info on these units, &
nothing online. After talking to a LG Tech at the factory, he said to
change all three power boards as a kit. Seems like they don't even know
exactly what's wrong with these units. Expensive repair. Has anyone
actually repaired the one board that is likely bad, or are no
individual parts available for the boards? Dani.
