    Can anybody please tell me what the signs of a dying bulb are ?

    specifically themescene H78 dlp .

    The bulbs only got 266 hours on it but after projector is turned on for 20-30 minutes the picture starts to flicker and smear and dither > a reboot of the warm projector solves the problem and then it comes back after 10 mins

    thanks

    Don't see how smearing and dithering could be related to the bulb at all. Flickering, maybe, but as the three symptoms occur at the same time, I'd say your bulb is unlikely to be the culprit.

    Agree with Nigel, the bulb isn't going to cause those sort of problems. It sounds like the problem is temperature related.

    If the projector is ceiling or shelf mounted then take it down and try it on a table or somewhere with better ventillation. Does it take longer for the problem to appear? If you are still getting problems than the cause isn't ventillation, it could be a dry joint or some component being affected by heat. Return to manufacturer in this case.

    Regards
