I have the same problem that you had, but with an IN76. I have replaced the inner fuse, but it wasn't that. When I plug it in the fans spin for 1 sec and that's it. It wont switch on. Did you eventually find a solution?
Thanks so much.
I'm too cheap to buy those expensive InFocus brand lamps, but it is caveat emptor out there in places like Ebay. My first purchase of a naked in76 bulb from China was fine, but I installed it wrong and the insulation eventually burned off the wire after a couple of years. I had bought the in76 used, so I decided to buy a replacement bulb right away and keep the original as a backup.
For my next purchase, I was determined to buy the bulb complete with the housing, so I didn't have to take the housing apart and put it all back together like I did the first time.
I bought from a seller who advertized "Brand New, OEM Lamp, Taiwan Burner, Japan Material, Not re-lamping, Not a third party knockoff." Sounds good, right?
It turns out the housing didn't fit into the projector well at all. The housing was not an exact match for the old housing. When I turned it on, the picture looked kind of fuzzy. When I took the housing back out and looked at it, the glass in front of the bulb had cracked and frosted over.
I wrote back to the Ebay seller and asked for a replacement glass. I didn't want to send the housing back because the lamp was O.K. and the shipping costs would have increased my costs to an unacceptable level.
After several emails and weeks went by with no replacement glass or any offer to compensate me, I gave the seller negative feedback, and he promptly responded with a cash rebate offer if I would remove the negative feedback. This was satisfactory to me.
I cannibalized the housing and put the new bulb in my old housing and used small parts of the old housing too, and it is still running fine after six months.
So far, I've been lucky, but It is a jungle out there for bulb buyers.
