I made the mistake of "loaning" this pj to my teen son for x-box duty in his room.

Now- it is dead. My son, of course, knows NOTHING.

It won't run at all. I flip the switch and its dead. Is there a breaker reset on this, or does everything 'tank' if the bulb blows?

Thanks!

Try reseating the bulb by unplugging it, take it out, put it back in and plugging it back in. While it's out, inspect it to see if there are any signs of it being blown.

But in my own way, I am King. Hail to the King, baby.

My guess is your son dropped it off a table and knock something loose possibly killing your bulb or PJ itself. Agree with reseating your bulb and if it does not help then try to open it up to see if there is any obvious loose cabling. If not and you're out of warranty then you're out of luck.

Thanks gang. I'll give it a closer look. It's a few years old now, so no warranty, I'm afraid.

Don't be so quick to blame the teenager - the fault could very well lie with Infocus and their lack of QC. I had the exact same thing happen with my 4805. One day, I aim the remote and nothing happens. I replace the remote's batteries and my 4805, which is still firmly mounted to the ceiling and hasn't suffered a fall, abuse, etc..., is simply dead. Infocus eventually fixed it under warranty but I never found out specifically what was wrong with it. I also had a bulb blow at around 1200 hours (mostly on econ. mode, with most hours racked up in 4+ hour blocks) and a month ago I started getting the colored banding from a bad light tube, plus my fan began shrieking like a circular saw, so back it went to Infocus. That $170 I paid for an extended warranty on this unit (includes bulb replacement) sure was money well spent.

I'm moving to a new house this summer and my 4805 is going to stay in the old house as a highlighted sales feature. I won't be replacing it with another Infocus projector, either (maybe Benq W500).

He probably took your projector out as revenge for not letting him get a driver's license.

You mentioned the unit is a couple of years old. Are you close to, or at 3000 hours? I had a similar occasion with my 3 yr old 4805. When I exceeded the 3000 hour mark, the unit did an auto shut-off. I thought it was dead and tried resetting the bulb. That didn't work, but what did work was performing the manual hour reset. After that, it fired right up again and is chugging along to 4000 hours.

How do you reset the hours if you can'nt fire it up. If you do that you will run the risk of blowing up the lamp inside of the unit and damaging the color wheel.

If you hold down both volume buttons on the projector for 10 seconds, that will reset the hours counter. It's the only I found to reset it when you can't fire it up and use the menu. This is using the original software, 1.0.2.

Har! yeah I expected a remark like that to come this way... (grin!)

Believe me, it's justified. He won't be borrowing anything else high-$$ until he's got the character to do the 'right thing' if he breaks it. He's the first person to glom onto something cool of somebody else's but pulls the "This aint my problem" bs he projects when he breaks it (something he learned from his biological father) and I nor his mom have taught him that- so that bs has flat worn out.

No money tree in my backyard...

That said, in this case he may well have had NOTHING to do with the 4805's current state of affairs...
I'll check the rest as listed here.

Thanks, gang!

I'm guessing we had about 1500 hours on it. Maybe 2k, tops. I'd be surprised, actually if it were that high.
