    Lamp/Projector problem

    Can any one help please. I have an infocus 4805 and when projecting there is a brownish line down the right side. Is this a lamp problem. I have taken the lamp out and cleaned as per instructions but this has not helped. Im lost as to what to do.

    Thanks

    Is it a straight line? Clearly defined edge? If it's more like a blob than a straight line, it's probably dust in the optics somewhere. Can you post a pic? Do you see the line when projecting a solid white or gray image? Black image?

    IIRC, the 4805 is DLP, right? If it's LCD, it could be a polarizer panel going bad (sometimes they burn up from the heat).

          Click the "post reply" button in the bottom left corner, or "Go Advanced" in the bottom center. Then on the new screen click "manage attachments", and follow the instructions!

          Well, we're safe for now. Thank goodness we're in a bowling alley.

            It's probably the dreaded 4805 light tunnel failure. You'll either have to cough up repair money or do surgery on the guts of the PJ to remount the mirrors lining the light tunnel, since one of them has come unglued and is blocking the light path:

                  Poor Infocus 4805 Lamp Life
                  by toohighpsi
                  Well I was really happy with the performance of my 4805 untill a couple days ago. I've had the projector for about 10 months and while my kids were watching a movie the other night the lamp exploded. (it was nothing short of an explosion either, I heard it from the second floor and it's mounted in the...

                  lamp counter has exceeded lamp life hours
                  by TheAberdeenKid
                  Okay now. I have an Infocus 4805, which I bought in August of 2004.
                  I went to turn it on last night, but the LED blinked twice, no picture.
                  I looked up the error code this morning, it is:

                  The lamp counter hours have exceeded lamp life hours. Replace the lamp and reset the...

                  Infocus 4805
                  by trisailerman
                  I have been very pleased with my Infocus 4805, but recently I noticed that the upper left corner of the image had a shaded area. The color was still good , but there that area of the screen was noticeably less bright. I also noticed that on power up before the lamp became too bright to look at, when...

                  by ToddT
                  I'm attempting to setup a 16x9 80"x45 DIY projector screen.
                  I have the projector installed on the ceiling.

                  I am having a problem getting a consistent horizontal size from the SP4805!

                  I started by projecting a blank (blue) image onto the wall and then used the...

                  lamp on my Panny AE900U / need input
                  by sirbogey
                  To all fellow AE900U owners, can you share some light?

                  My PJ is 2y old and the lamp reached 2100 hrs. Starting at around 1800 hrs, the hours in the menu started flashing red. Once the lamp reached 2100, the pj would automatically shut down and restart again on its own. This happened twice...
