4805 w/less than 300-400 hours has blinking red light
I went to turn on my projector tonight....it never projected. It tried to get going a few times, then I got a blinking red light. I don't think it's the bulb - I think it has less than 300 hours on it - maybe 400 at the most. I pulled the bulb and it looks fine as well! After the projector's final attempt to start, I hear an intermittent wind-down sound.
This is really aggravating on a unit with so little use that I bought new...anyway - any ideas?

the high-pitched sound is the colorwheel trying to spin up to speed. that may need to be replaced. check the inside of the lamp for bulges, black spots, fogging or flaking. if it has any of those, replace the lamp. you can get parts from an infocus service center or send it to them for repair. either way, try www.avsolutionsny.com they're really good. if you want to replace it yourself, there is a detailed step-by-step on my "tips" area. it's the same as the infocus x1, x2, x3 and sp4805. click on my picture and scroll down to tips. good luck!
if the led flashes once in 2-second intervals and you don't hear a high-pitched whir, the colorwheel needs replacing. if you do, the ballast is bad. if it flashes 2 times, the lamp is past 3000 hours. 4 times, fan error. 5 times, temp too high and it needs to cool.
Try resetting the projector by pressing and hold the two Keystone buttons, then turn ON projector. Hold down the two Keystone buttons for 15 seconds, then turn OFF projector.
Turn ON projector, the new lamp should strike.
Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.
Let me know so I can help trouble shoot other possible problems.
There is a cooling off period that your projector will do in order to make sure it does not implode or improperly destroy your lamp. It is very fragile and each time you turn on your projector it lights up almost like you would light up a candle. Each igniting of the lamp creates a decrease average of 3 hours per turning it on/ff.
also, have you tried another lamp and reset the hours, or cleaned out the filter at all?
Let me know how things go for you. I wish you well and hope that helps fixes the problem.
From the infocus_lp650 manual Table 2: Red LED Behavior Explanation One (1) blink The lamp won't strike after five (5) attempts. Check the lamp and lamp door installations for loose connections. Two (2) blinks The lamp counter hours have exceeded lamp life hours. Replace the lamp and reset the lamp hours counter. Optional Accessories Part Number Three (3) blinks The projector has shut down the lamp. Replace the lamp. Contact Technical Support for repair if replacing the lamp does not solve the problem.. Four (4) blinks The fan has failed. Replace the lamp (the lamp module contains a fan). Contact Technical Support for repair if replacing the fan does not solve the problem. Five (5) blinks The projector is overheating. Check for a blocked air vent. Contact Technical Support for repair if clearing the air vents does not solve the problem.
