The Blue CRT ( Picture Tube ) has a short. You may be able to do a temp fix by turning down the Blue CRT drive level ( Located behind the front speaker grille )untill the lines disappear. But its only a temp fix. The Blue CRT will most likely need replacement.

The brightness is very dark. Any nightime scene


Your CRT's getting old. Plus dust on lenses don't help much. You have to open front frill (below screen) and back of the TV. Clean up lenses using dry paper towels, do not wet.
In front of the TV after grill remove center cover and locate "black box" that have 6 potentiometers on it that looks like plastic adjustment screws for philips #2 screwdriver slots. 3 of them should read "Focus" These you don't touch. Another 3 reads "Screen". Put some still image on your screen (like paused DVD movie frame). Carefully add brightness in all 3 colors trying to avoid horizontal lines appearance. If lines show up, just turn it back a little. Try to keep color balance looking at the picture.
This procedure will brighten up image but further reduce CRT's life.

In case that you posted wrong model here and you have DLP Projection TV - just replace the lamp.

Black/dark line down the edge of the projected image.


the light tunnel is collapsing. you can purchase the part from, or send the projector in to, an infocus authorized service center. try av solutions in ny. they're pretty good.

if you do chose to do it on your own, buy the part (315-0053-01). the tunnel is a rectangular mirrored tube located under the colorwheel between the lamp and the lens.

I have an Infocus LP350. The image it displays has lines running through it, which consists of the text displayed, but offset and a bit jumpy. There are also some dark black lines on the right. How can I...


if you reset the settings to factory default and the text is still like that, you have a colorwheel issue and probably a dmd chip problem. as for the dark lines, if they are more of a shadow on the edge, the colorwheel is collapsing. if they are thin and definite, you may have a main board or dmd chip problem.

Black Lines


Do the black lines only show up when useing the adf???? Or do they show up on both the adf and the copyboard glass??? If it is only when using the adf...... The fix is easy.... you have to clean the smaller piece of glass that is to the left of the copyboard glass with windex or rubbing alchola. If it is with both you may need a new drum and blade or a new ufr... Good Luck
