Have had this unit about 6+ years, replaced the color wheel a year or so ago. Just recently it started turning off and on and off and on and off and on repeatedly. Then it would be fine again for a week or so and then start that off on thing again. Got in touch with Samsung, thought it was the Lamp, replaced the Lamp. Worked again for a week or so and then started the off on thing again. called repairman, said 320,00 to remove and replace the DMD board.
Anybody have come across this problem???
