Sony KDF-55WF655 LCD projection tv

Im trying to figure out what is wrong with this tv ..

The picture is very dark the brightness is all the way up but still dark ..

I've tried 3 new lamps same part number as the original and 1 other but still same result the picture is dark ..

Wondering if anyone has any ideas on this and could guide me thru troubleshooting or might know off hand what to check ?

Any help would be appreciated ..

Its a good chance the optic engine is bad (burnt & discolored optic filters), If you can supply an all white signal does it look uniform or does it have a blueish area in the center of the screen? Also what was did the area around the lamp and the lamp door look like? did it look over heated (like Hillary

The area around the lamp looks good no discoloration ..

If I supply a all white source it's uniform no blue areas
