I have a HL-T5087S DLP and I do not have an issue with color. When I turn the tv on I get a Mosiac pattern. I can change channels and I get sound. If I turn the tv off and on two or three times the picture comes in and plays great. I did a test for the DMD board and it checked ok. I suspect the main board more than the DMD board. The main board is difficult to find. Can I use the main board from HL-T5687S?
