Question about InFocus SP-LAMP-019 Projector Lamp for LP600, C17
The light tunnel inside the "engine" is either out of alignment or the glue holding the tunnel together is coming unglued and 1 of the 4 sides has fallen in. There are 2 screws to adjust this if the tunnel is still intact. One or both screws can be accessed by opening the lamp door and then you have to remove a thin sticky cover. You will see 2 small screws that will have to be adjusted with a small torx (3) or allen. You will have to have the safety switch pushed in with something and adjust while the projector is on, using the most easily accessible screw, turn it towards the direction of the "banding". It should decrease. If not, turn the screw the other way. The screw that is not so easy to get to is for adjusting the banding the can appear across the top or bottom of the screen. If the banding gets worse or even starts to show diagonally across the screen, it is a good bet that the tunnel has collasped.
