Hi, my projector is a pt-ax 200 the picture drops out intermittantly i have a 10 metre hdmi cable running from dvd player to projector. when the picture drops the input menu flashes twice then the picture comes back not sure if the problem is the length of cable or projector itself. any help appreciated.

The manufacturers lenses are always made for optimal performance of your projector. When it comes to projectors with several lamps I have only been working with the Panasonic PT-D10000. Panasonic recommends that all lamps are changed at the same time for two reasons: a) More equal performance and b) uniform lamp time. If you change lamps one after one you might end up with reduced performance both in light output and color quality. Of course, 4 lamps at the same time is a bit rough on most budgets, but that unfortunately is the prize to pay for having to use 10K AL projectors. Maybe AV_Integrated can provide more and better info than me on this issue.
