Question about Optoma EP719 XGA DLP PROJECTOR 2000L 2500:1 CONT DVI-D WITH HDCP Multimedia Projector
When my display comes up on the screen the Optoma logo is clear & stable. But then when I open my Power Point presentation the display on the screen seems to jump a bit as though it has a continued heartbeat or pulse. It began doing so a couple of weeks back during a seminar presentation, and today when I tested it, it did exactly the same thing - as though the projector has developed a heartbeat every couple of seconds.
It is one of the fan, it is bent or out of place and cause reptead disturbance at cyclic intervals. The projector must be taken apart and examined on the inside
