I have an ASK Impression 880 LCD projector. I need to know how to reset the lamp life warning. I assume it's in the service menu, but I don't know the code to get in. I already replaced the lamp and ballast, because the old ballast blew quite spectacularly a few months ago.
IIRC : There is a switch on the motherboard. Turn unit off (unplug), open cover and set switch (only one on mother board) to opposite position that it is in. Put cover back on, plug in and go. Thats all................
Thanks. I remember seeing that switch and wondering what it was for. ;) I previously had the unit apart to retrofit a new lamp and ballast, after the original ballast blew up in spectacular fashion.
Maybe if I'm lucky I can reach in through the lens hole with a diddle stick and flip the switch, so I don't need to take the whole thing apart again. ;)
Well, I took it apart, but I couldn't find a switch anywhere. I could have sworn I remembered there being one, but I also used to have a very similar, but slightly older, ASK projector and it could be that I'm remembering it, instead.
Under the OPTIONS menu, there's a SERVICE option that I suspect is the answer, but when I select it I get a little box that says "SERVICECODE?" and I'm not sure how to proceed from there.
I need to figure this out because, without a reset, after another 50 hours the projector will shut itself down and become a very large paperweight. ;)
Sorry the switch information was for the ASK 960. I have changed lamps in the ASK 880 but can't find any information on resetting the timer. I seem to remember removing the lamp "tripped" a switch. Maybe you have to go into a menu or something while it displays the lamp timer message. You may have to remove the lamp again and "trip" the switch. When it is turned back "on" the firmware will sense the lamp change and you will have to either "agree" it has been changed and push the correct button or "disagree" by doing something else. Keep trying as you will figure it out. I figured it out and didn't make any special notes. Good Luck.
Hmm. I don't remember anything special on the lamp sockets. They seemed like typical HID bulb sockets, just one wire per socket. Perhaps a complicating factor here is that the original lamp sockets, ballast, and ignitor are gone. I retrofitted generic replacements after the original ballast blew up. There were two temperature switches on the brackets that held the lamp assembly, but I put those back in place.
I suppose it's possible there were some kind of sensing electronics in the ballast or ignitor that could detect a new bulb, but I don't remember noticing anything special about the wiring for those, either. Like my other ASK projector the lamp ballast seemed to be powered by its own tap off the 120V input, completely independent of the display electronics.
Maybe I'll take it apart again and give the lamp compartment another careful look, some time soon.
I only replaced the lamp rest is still original components, don't think it will reset by itself there must be someting hiding behind the service menu otherwise they wouldn't lock it with a code. Wrote an email to euro support@infocus and asked them how to reset the lamp timer but ofcourse they pointed me to a repairshop, you got to be qualified they said, working with this stuff for almost 30 years I count myself as qualified :) I'll be back as soon as I get any useful info. Cheers!
