    Hello,

    I have a fairly new 3400mp that has video problems on start up. I have 2 known good lamps, one of which is in the unit. Originally I thought the problem was a power supply issue and I have replaced that.

    What happens is that it appears to go through a self check a start up, the output is dim and I see it cycle through a few colors...then stops...all when the "lamp" notification pops up indicating it needs a new lamp...it then shuts down. To start it again (to have it run through the above cycle), I have to unplug it, plug it back in and it will restart.

    Does anyone have any suggestions as to what the issue might be?
