I'm working on this Samsung DLP and am having trouble getting it to start. It will usually light right up on the first power-up attempt of the day and stay on indefinitely, but subsequent attempts to boot it usually fail before the set gives up and blinks all three lights on the front of the case.
My first instinct was a bad ballast, but I'm not entirely sure that is the case because the set makes a humming sound while the lamp is actually lit (the best way to describe the noise would be to imagine a loud laptop CD drive loudly spinning a CD) (neither the lamp fan nor the ballast fan are responsible). Is it possible that there is a fan or color wheel (that is required to be up to speed before the set tries to light the lamp) somewhere that is being blocked or failing somehow?
