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.
I have an InFocus IN72. Everything has been working fine until yesterday. I can no longer get any connection over the HDMI port. I've tried swapping out the HDMI cable and have tried different devices (2 Roku Boxes, computer, etc) and the projector won't connect to these devices using HDMI. Everything works fine if I try to connect something via S-Video or Composite/Component.
I am running firmware 2.5, and it wasn't until I read related posts in this forum that I realized I may have unknowingly run into the 1 input firmware bug.
I have ordered an M1-A to DVI/USB-A cable and crossing my fingers that the firmware upgrade to 2.9 will take in a Windows 7 environment. I read much of needing an xp notebook, but who has that around anymore? I am going to attempt to run the Infocus Flash software in "xp compatibility mode" at the very least.
More frustrating still is the fact that I have a simple M1 to Dvi adapter already, but the little attachment only sports a USB receptacle at the DVI end instead of a male end for some unknown reason. Making it utterly useless.
If anyone has any experience with the upgrade on a non xp machine, I would really appreciate some pointers about going about this.
I tried this on Windows 7 and never got it work due to the device drivers completely changing in Windows Vista/7. I don't think Infocus ever updated theirs to support this. I gave up fairly quickly and ended up having to partition off my hard disk and set-up dual boot with Xp and Win7.
But saying this there is some stuff on here about it which could work:
Another option is running XP Mode on Windows 7 (like running a Win XP Virtual Machine):
As I never tried this would be interesting to know if its possible and actually works.
Btw the fuse in question which people have changed is the one on the ballast board (in the middle under the metal cage/heatsink). I Think the one you mention is the filter board (where power cord plugs in) and normally that doesn't tend to blow.
But it sounds more like the firmware issue in your case given you hear a squeak from the power supply.
I didn't realize there was another fuse onboard. I know I had the projector sent in to infocus a while back for a warranty issue (dead projector) and fuse replacement recall or something. The firmware was upgraded from 2.1 to the "then current" 2.5 at the time. I should have held onto the old ceramic fuse I guess. Probably nothing wrong with it. Replaced it with a glass slow blow 5A/250V one any how. That's before I heard about the software issue; I likely made more trouble for myself. Then cleaned the fans, etc, out with some compressed air.
I also read someone posting above had their projector recognize the software only when powering up holding both direction arrows simultaneously. I'll try that, as well, when I receive the cable if it's not automatically recognized.
I had just under 10000 hours on the current aftermarket replacement bulb. For the time being I'll likely stick the original in again if I get the in76 functioning, as it only had 3000 hrs on it when replaced when the warning appeared. Plenty of life left!
Connected the M1 to usb cable to projector and pc, and when loading the dld flash file, nothing showed up to Flash or Download in the app. Then read a previous post about holding down the two arrow keys while connecting the power cord and voila the familiar USB connection bloop sound emanated form the computer and the projector was recognized by the FlashUSBIII app and the Download button became selectable. Hit the download button in the app, and old firmware erased and new one downloaded after ten minutes; when update completed everything greyed out causing some worry, and then the fans came on shortly after and the lamp illuminated. Success.
Very happy, and thanks for the help.
