Projector has vertical white lines - InFocus SP-7205-RE Projector, Factory Refurbished Multimedia Projector

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.

my acer projector show the verticals lines on top

Hi fabiano did you ever find a solution the vertical line in your RD-JT91 Multimedia OH projector. I now have the same problem. Gary

bad pcb. get your money back.

that is due to lcd filter units , try to align, precision work

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.

I just read a post that said tap on the top and the line will go away. I tried it on mine and it worked! I had to tap it fairly hard. I just kept tapping harder and harder on the plastic in front of the buttons and voila! The vertical white line disappeared!

I had a smililar problem after taking it apart i realised that i had screwed my mount skrews into the video main board and cracked it along with a few soldered wires, if you havent done any physical dammage to it try a firmware upgrade

Hi there

This problem can only be fixed properly by replacing the Mainboard.

I have a Dell 2400MP projector that had the same problem of vertical white lines appearing over the screen.

This may seem like a simple solution, and I don't know if this will work for you, but the way I solved the problem was simply to press the bottom side of the projector, until the white lines disappear . Until now, the problem has yet to resurface.

Here's some simple steps:
1. Turn on projector
2. Connect projector to computer
3. Focus projector
4. If white vertical line appears, firmly press underside body of projector
5. See if vertical white line disappears
6. If not, try slowly pressing other parts of the body of the projector and see if white lines disappear.
7. If solution doesn't work, you may need to send it to the service center.

Hope this solution works for you.
