Possible fault on the mother board as there are noise on the LCD display. You might need help to sort this out if the fault does not clear even after the lamp works for some times.

this projector does not have lcd's. it has a colorwheel and a light tunnel. the light tunnel has probably collapsed and needs to be replaced if you have distortion in the middle of the display. if it were to one side or the other or a the top or bottom it may have been adjustable. But wiith it being in the middle, I'd have to say you needed a new light tunnel.

Sanyo lcd projector has horizontal scrolling lines in its picture. Is this different than a lamp problem? Electrical? All else works fine. Thank you. Sanyo PLC-5600n lcd video projector. Not a tv.


This is caused by the processor and not by the lamp. As you might know, these projectors display colors by blanking out the light with lcd pixels. Most folks don't know that any display devices such as displays on cameras, laptop displays, etc. use an amazing amount of original technology that powered CRT TVs. (Yes, even vertical hold, although done electronically today, is there.) You'll just have to send this one in for service.

Vertical line white, regular, blinking.


I don't think it's the bulb. Sounds like an LCD panel issue. Maybe one or more of the 3 LCD panels is either not working right or the unit has been dropped/jarred and the panels have moved (All three have to line up right optically to give the right colours). You need to take the projector to a qualified service centre.
I hope that solves your Problem, If so kindly accept it.
Thank You, Arjun.

Lp70+ display shows a solid black vertical line


the light tunnel is either collapsing and blocking the light going through it (and needs replacement) or the vertical/hoizontal adjustment of the tunnel. if you take the lamp out and move the colorwheel (with a pencil eraser) to the clear section, you should be able to see a square through it. if part of the square is blocking the middle, the tunnel needs replacing.

by the way, on some projectors the light tunnel is called an integrator rod.
