Question about Samsung Televison & Video
I have seen a similar issue with exactly the same model. If the tv is not detecting that the door switch is closed then my money would be on the sub-detect board which checks the status of the lamp door. The part is very inexpensive(about 15$) and that should be the first thing to replace to see if the issue will be resolved.

Fault protection. How is your B+ voltage to the projection lamps?
I've often seen this problem and a SIMPLE B+ change out will fix the problem.
Here is what you are looking for to replace. This is right on the power supply and they tend to fail over time. Considering your tv is a projection, I highly recommend the replacement of the B+ flyback transformer.
Thank you, hope this helps :)
