It sound like either the connection IS bad or the projector is bad. Try taking the projector back for another, it may be defective. Other wise it sound like the bulb is burning out but not likely after only 2 weeks.

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.

VERTICAL WHITE LINES


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!

Follow up on the Optima 719 with vertical white line


Hi Abouttime

Tapping can fix most electrical things for a very short while - unexplainable !

But I have been working as a authorised service provider on mos brands of Projectors for over three years now and in all of the times the white line was a faulty Mainboard.

This is just my opinion and I only answer and provide a free service to those who are in need.

Wheter you take my advice or not is entirely up to you.

Kind Regards

Marrie

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!
