Samsung HL-T7288W DLP TV
Model Code: HLT7288WX/XAA
Serial #: AJ893CKP500321T
I am getting (constant) white dots on TV screen. I don't know if my problem includes the DMD Board, the DLP Chip or the entire Optical Engine. I have an understanding of electronics and would like to fix it myself. But I don't know what the exact problem is or what part to order (e.g. there are two types of DMD Boards for my TV model).
