No need for a new power supply I can repair them at a lower cost. My ebay ID is Gtitubro.

I just got back my power supply that Neo32/gtitubro repaired. He did a great job, I'd recommend him. I had first tried several sources to get the power supply board, but both were unable to get it, so I was ready to junk the PJ before I found this board, he repaired it cheaper than it would have been to get the new board if it had been available.

The projector would not turn on and had a flashing red light for the lamp. Knowing it was an older projector when we rented the building I purchased a new bulb for this projector. When I put the new bulb...


PROBLEM :-The power supply of the projector is faulty there is a transistor witch is switch 15 volts for the lamp drive board.

SOLUTION: Remove the upper cover with 6 screws back side of the projector.
remove main board and lamp cover with 7 screws.(show in the picture)
remove upper cover of the power supply and lamp drive unit with 3 screws.
remove power supply unit with 4 screws and 3 connectors and put face down on the table.
now you find the transistor no Q107 and replace with the transistor no 2SB710 is and surface mounted compunent(show in the picture)
fix it all as you open.
power ON the projector and enjoy

(doing very carefully This is a technical job)

The RED (of RGB) is not firing


Its a problem in either your cable or the projector board. Get a new cord, if the red still dosent work either purchase a new board (expensive) or buy a new projector (slightly more expensive, but worth the investment with the board going out probably more parts to follow). You decide wats best for you.

No pwer to Infocus sp 4805


My 4805 made a loud pop noise and smoke and died.

I thought it the bulb and wasted $340 on that purchase.

They are subject to overheating and the main circuit board may be fried.
It cost me $50 for a tech to confirm my suspicons of the same.

Look at the main circuit board and you might idenify a scorched
overheated area.. My shop told me you can purchase a new main
board.. Diagnosed by no power to the bulb...

Bulb failures


I experienced the same thing, only to discover it was the ballast that powers the lamp. I believe INFOCUS repairs for $390.00 per the technician that I spoke with on the phone at INFOCUS.

RGB not aligned so I get thin red vertical stripes displaced to right of icons


If you are handy with allen wrenches, quality screw drivers, and the like, you might 'try' opening up the can of worms and gently manipulating the red LCD panel (it will be obvious--a magenta color when off), by slightly loosening the holding screws, then moving--ever so slightly, the panel untill the ghost disappears. Do not do this though, untill you mark the present position on the top and bottom of the LCD panel. Take pictures, far and close-ups, as you go so you can reassemble the unit. The typically three LCDs can be located by finding the prism cube, located under the circuit board, and just before the output lens. Be patient, and have fun. I did this with an 'out of wack' throw away, and now it is just as enjoyable as my 'dimmer' HDTV projector. Even side by side, from 8 feet away, when both are making 72" images, the HDTV is barely clearer, Jon.
