I took the rear bottom off of the set,lots of screws to take off.
On top of the bulb housing is a small yellowish thermal fuse.
I took mine completey out,jumped the black wire together,and bingo.set works perfectly.

Your set uses the Phillips UPH100W 1.3 100http://servicemanuals.vstore.ca/ 1amp bulb part number 6912V00006A which uses Ballast EUC 6913V0002A and the actual ballast isMB03CA part number 6871VSMB13F I would contact LG and give them these numbers. Is your ballast bad or is the BallastEUC bad? Let me know if I can help you further.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).
