Question about Optoma Office Equipment & Supplies
The line seems very dominant on the bright long shot scenes. It is almost invisible in darker scenes. The line is like the edge of a glass panel as if watching the movie thro a glasss panel on one half of the screen.

take a look here: http://www.extremetech.com/article2/0,1697,1049289,00.asp "... The others, however, have lost portions or all of their blue channels. TI's theory is that the shorter wavelength and higher energy of the blue light apparently causes the organic polarizing material in the LCD to get lightburn much faster. TI showed us a damaged LCD panel that controlled blue light transmission, and there was a large spot in the center that was apparently burned out..."

mine does the same thing but i can see the whole screen it's just half height full width, above solution about zooming to 1X is what i've been doing to fix it for the last 6 months, needs to be done every time I turn the power back on. Anybody know of a more perminate fix?
Now my power supply has gone have the projector in pieces, found a failed on transistor but because it's over heated can't read of it what type it was....
Already replaced two blown diodes in the main H-bridge
Looks like one coil will need rewinding.
If anybody has one in pieces I would be great if you can help me work out what the blown transistor was.

SOURCE: Vertical lines on projected image from a Dell Data Projector. White vertical lines are appearing at even spacing across the width of the image projected. At a loss to how to fix this. Any ideas as to
that is due to lcd filter units , try to align, precision work

I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.
