Question about InFocus LP 600 Multimedia Projector
have a problem with my Infocus LP600. It's three years old now, haven't used it a lot since then, maybe a few houndred hours. But now it stops starting up, the Countdown stops 2 or 3 seconds before the lamp should start, so i can see the message "Wait..... 2 seconds...". I replaced the bulb with a new one, but the problem remains the same. Any ideas??
Most likely, if it is a thermal problem, your main cooling fan has quit or is stopping after a short period. The problem is, I've seen several of these do this, and in every case, it is not the fan that has failed, but the Controller Board. And that is a very expensive part.

that model has a history of bad ballasts. you'll need to replace it.

Testimonial: "Of all the comments on lamps failing to power up, only this answer fits my circumstances. I eliminated other "solutions" posted on FixYa. Thanks!"
SOURCE: lp600 won't strike
I had a bulb "expire" on me (went out early), giving the "Lamp didn't strike" message. I replaced it with a spare and unfortunately that gave the same message. I RMA'd it to InFocus who "fixed" it, citing a bad bulb. "What about the spare I used?" I asked. "Oh well" was the answer.
I got the projector back, tested it and it worked fine. So I decided to test the spare bulb I had previously, still got the "Lamp didn't strike". I thought "bad bulb after all". So I put the bulb InFocus had fixed the projector with back in, started the projector and received the "Lamp didn't strike". (ie, a known good bulb). Oh ****.
I left the cover off, jimmied the safety catch and restarted the projector, heard some snapping which reminded me of a bad electrical connection. I popped the top cover off the projector and saw where the electrical plug was that the lamp plugged into. It looked fine from the top-side and the bulb compartment, but when I used a small screwdriver and pushed on it, it dropped a quarter inch and a little plastic tab reseated itself. I realized when I had put the spare bulb in initially it had pushed on the electrical connector, not quite lined up, and pushed it up slightly into the body of the projector. The bulbs looked like they were plugging in, but the connector had moved enough the bulb wasn't making contact, so not getting power through the plug. Once I pushed the connector back down into place, I put my original "spare" bulb in, carefully lined up the connectors, and it fired up fine. (Big relief).
