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.

You can check with LG in Huntsfield, Alabama. They will probably say you
need to be replaced as a kit to "CYA". Many of their PDP units are board
level. Ask if they have any kind of refurbishing process for the boards.
Also ask if they could send you some of the training manuals, good
information.
As far as the individual components, you could probably order them after
tearing the three boards out of the set and doing come rather diligent
diagnostics.
Modern Consuner Electronics, Eh!! IMHO

Not to mention some serious reverse engineering as getting a schematic
for these units is nearly impossible as they are board level repair and
the service manuals do not contain the schematic.
