I have a Samsung DLP HL-R5678W,  when i turn on the TV the screen flickers (white flashes) and after about a minute the screen gragually turns very very bright (almost white) from the bottom of the screen to the top. I spoke to a tech, he said that it was the DMD board, which is very expensive $900-$1000. 

Can anyone confirm this diagnosis or can I fix this with a simple lamp replacement?

Help!!!
