I suspect the power supply. All discrete component look fine. (no bulging or leaking capacitors, no burnt components, etc). Model- UN50F6350AF, PS- BN94-06554A What component would be most likely to have failed.
Replace the power supply. It is gone

Thats the error for lamp driver error. Which means the Ballast is most likely defective. You can get the replacement ballast for your model at the following link which comes with installation instructions.

This is most likely caused by the Main Power pcb.
See Fujitsu Service Bulletin on this problem in a similar model from Fujitsu. -see link below

A competent service technician should be able to implement the service bulletin.
A similar service bulletin is probably available for your model.
Request bulletin from Fujitsu '[email protected]'

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.
