be sure and reset the lamp hours. Flash the software if you can. These are also notorious for the ballast cable on the inside of the lamp housing backing out when a lamp is removed or replaced. If you have the cover off push the cables back into place and hold them there as you install the lamp. Also look directely at your lamp in the center and move it side to side and up and down. If there are any cracks or frosty looking spots or bubbles in the mirror of the lamp that are visible, then the lamp is probably shot. If all this fails, most likely it is the power supply, or the lamp door has gotten mishapen from heat and the actuator on the lamp door isn't making full contact with the safety swith.
there isn't a colorwheel in the sp5000. it's an lcd, not a dlp. one of the fans is bad and needs to be replaced. the bearings might be going. you can get parts from an infocus service center or send it to them for repair. try av solutions in ny. they're really good. www.avsolutionsny.com
the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try: http://www.infocus.com/service/asc/communications/tech_notes/2006/09/tn495g.pdf
there isn't one. you need to see the menu. but what color is the led and is it blinking?
green- all is well
red blinking:
1 time- lamp not striking after 5x.
2 times- lamp has more than 3000 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fan failure. shuts down.
5 times- undiagnosed error. possibly ballast or colorwheel.
if the colorwheel won't spin, the lamp won't light. when you turn on the projector, do you hear a high-pitched whir? if not, the colorwheel needs replacing.
either the light filter behind the blue lcd panel or the fly-eye lens (both inside the optical engine) have developed a burn spot from overheating. infocus doesn't sell individual parts for the optical engine, and the whole thing must be replaced. but unfortunately, it's the most expensive part of the projector, usually upwards of $2000 (and there's none in stock).
