I have a Samsung HL-S4666W that has been working great for 15 months, but recently small white specs have started to appear on the screen and multiply in number every time the TV is turned on.
Samsung tech support says it sounds like the DMD chip is failing.
I have found a DMD board (ASSY DMD BOARD P, part #BP96-01580A) that is the replacement, and some posts say the DMD board is like a motherboard in a PC. Also learned that this is expensive for a service person to repair - almost the cost of a new unit !!!!
Question is:
1- how easy is it to replace this board for a technically skilled person?
2- how easy is it to get to the DMD board ?
3- are there any optical aleignment needed after installing this board?
4 -are there many settings or adjustments on the board that need to be made once installed?
5- any photos or schematics online of this board and its locations in the unit?
Note: the online manual shows photos for replacing the lamp, and off to the right side of the lamp cover is what looks to be a vertically mounted board. Is this the DMD board ??
