    I have the same problem (white vertical line about 2-in from left side) ... after only 3 uses in 11 months of ownership ...
    ... problem occurred 1st with VGA-input, tried using S-Video Input which had no problems...for about 2 more uses... then, SAME problem.
    ... at this point, both VGA inputs and S-Video input have the same white line.
    sounds like something in the input board(s).
    Does anyone have a solution ?? Kindly advise...thanks!

    I get 3 vertical lines on the right side of the screen everytime I turn it on. Tapping the projector on top a couple of times use to fix it but not anymore...

    I had the same problem occur after I had owned this projector for just a month. Tapping it on the side made it get even worse, which makes me suspect a bad internal connection.  There are several multi-pin connectors inside the unit. 

    I sent it in for repair after the first failure and it came back and after using it a month it did it again.  I took the case off and looked at it and put it back together and it worked fine.  Now it is doing it again.

    Guess I will try it again.

    I can't seem to get the cover off. I'm afraid I'll break the tabs. It seems to be attached right under the center of the cover. What's the trick?

I just got done fixing this problem. A vertical white bar was at the left 3rd or so of the display. I open up the projector (which required taking a steak knife to the center screw column since there's a unique, tiny screw that has to be removed), removed the shielding, and ensured that all the connectors were snug. Many of them were crooked and not seated in their sockets. I also removed and reattached all the ribbon cables, including the one that goes to the color wheel. The vertical bar is gone now. I have let it run for about an hour now with no failure.

I have the same problem. Read another blog and they suggested that the tilt of the color wheel could be a problem. I have not had the opportunity to test it, but it may be right as the last time it was used it was okay until the "picture" was elevated (read: the machine was tipped up further). This would be an easy fix if this is the answer... just wanted to pass it on...

It's either pins that need to be reseated, or the Vertical display IC has gone bad. Open up the case, and make sure all connections are secure inside. If you are certain that they are all snug and nothing is loose on the board, then your problem is a faulty display IC. Replacing surface mount components is not for the faint of heart.

I don't have a solution but I bet the connector on the projector has a bad pin.

Seeing vertical lines on the picture

do the lines follow the same vertical pixel width from top to bottom or do they cross pixels? first try going into the menu and select auto-adjust. it just might be out of sync. you can adjust the resolution as well. if nothing changes, you might have a bad dmd (digital micromirror device). if that's the case and the projector is pretty old, replace the projector.

Vertical lines showing. it is an Optoma HD70

If the lines present in the menu when displayed this indicates device mounting troubles. Possibly loose in socket. If you change aspect of displayed image do the lines move, if they do, its an electronics problem, if they are constant, and nothing is displayed in the lines. Tighten device in socket, or seek professional service.

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!

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!
