I Have replaced the DLP chips to fix the white dots problem on my DLP Samsung model # HL-S6186W but another problem came up, it won't turn on. The chime will be heard, the green light flashes and then shuts down and then recycles, then the two green lights and the red light flashes, Nothing lit at the back (except for a small green light).. Lamp was replaced, same thing happens. Ballast was replaced, same thing happened. What can be next to be replaced. I would appreciate an output from you, thank you.
