Projector vertical running lines


Hi there

This is definatelly a interference from a power cable. If any of your signal cables in the ceiling is closer that 5cm to one of those , you will get interference.

The Company that did the installation should know this and I would suggest you call them and tell them that they should sort it out. They should either move the cables or insulate them by means of conduit.

White vertical line in the center of projected image


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.

Vertical Lines on the projector screen


When the vertical lines are displaying, open the projectors menu (by pushing the "menu" button). If the vertical lines affect the menu, it's a problem with the controller board and will need to be repaired. If the menu is NOT affected, it's probably a loose or damaged cable (Cable part# SP-DVI-A-R).

Vertical lines all over image after few minutes turn on


Well i think we have the same problem i with our proscreen 4700 and the only thing i found out so far is that the rca and svideo jack on the projector have gone bad. Tried the data connector and the video was perfect. Tested the rca jack with new cables and another dvd player and it was still mesed up. So it is the hardware that controls the input for the rca and s vidoe jacks but still have not found a way to get the case open to see if some thing can be fixed from the inside.

Vertical white line


My EP719 had the same problem. Did it once, briefly, soon after I bought it, then not again until recently, when the line came back more frequently and wider.

 

The projector was 20 days past warranty, and the company would not honor. So much for customer satisfaction and loyalty. Last piece of Optoma equipment I will ever buy!

 

Anyway, I found a web item on another model of Optoma projector with the same problem. The solution this guy tried was -- I kid you not -- rapping on the thing. With nothing to lose, I tried this on mine. Tapped lightly on the top and noticed a change in the width of the line. Hmmm ... it was sensitive to this.

 

Tapped harder. The line got narrower. Rapped pretty hard -- thump! -- and the line disappeared.

 

Since then I have been running the projector for hours, turning it on and off, letting it cool down, starting it up again. And the line seems to be gone. It may come back, of course, so this gonzo fix may not be permament. But if it works while I'm using it at a presentation, think of the amusement it will cause!
