Re: vertical line

Hi there

The only way of fixing this is replacing or repairing the Mainboard.

This is a common Mainboard failure on Projectors

I have a blinking white vertical line on the left side of my screen about an inch thick.

the connection between the main board and the light engine could be reseated to fix this. If that doesn't work the main board is bad or the dmd on the light engine is bad.

I have an Optima Model EP719 Projector. Suddenly I am getting white vertical lines and can't find a solution for removing them.

I would try switching out the DVI cable first. It could be faulty. This would be the easiest and cheapest solution to check.

Half inch crystal/ solid white vertical line on screen

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

Optoma EP719. I have a vertical flickering bar. I've tried adjusting the ''Frequency'' with no luck. It worked fine with my computer the last time I used it so I wouldn't think it is a graphic card issue.

I had the same problem and was having no luck but stumbled over this solution. Take the monitor cable going into the back of the projector unscrews the screws holding it in place and then pull out the cable just a fraction. Obviously not enough to pull it all the way out but just enough so it's not rammed all the way in. Flickering line disappears. Not super technical I know but it a solution.

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 line

Hi Abouttime

This is unfortunately a sign of Mainbaord damage to any make of Projector.

But do give this a go , you've got nothing to lose.

Try using a different signal cable and then pressing Auto on either the remote of the Projector or the Projector it self once the line appears.

Thanks for using Fixya !

HItach cp-s860 problem

I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.

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!

Vertical line on optoma projector

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...
