SOURCE: 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!

How about sending it back to the company? Since you are in the US (unlike me), they should be able to fix it.

Hi there

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

Hi there

This is a common problem on a faulty Mainboard of a Projector.

Not much you can do about it except repair or replace the Mainboard

What causes white vertical lines on dlp 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.

Adjust the horizontal in the menu then try the overscan adjustment. If the image does not look dim you do not need a lamp.

White Vertical line in the screen.


Again, this sounds like a light tunnel failure. See my other post about this.
I replaced my light tunnel with square brass tubing I picked up at the hobby shop.

I hope you are still under warranty. This is usually a problem with the main DLP chip seating properly on the board. I have rarely been able to correct this without getting a new engine board and DMD (digital mirror device).

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).
