bulb, thinking the lamp was the problem, as there was this green haze overshadowing the video. This did not solve the problem and I have played with all the settings on the menu (including, contrast, tint, etc. I don't remember the others. But, those too). I read something in the manual under the Troubleshooting section about adjusting the 'tracking' as I am getting some line flickering too. But, I don't see a 'tracking' button on the remote or the projector itself. Question: How do I resolve the green haze and the flickering?

Tracking would only apply to the overlap of the images, so if you were having a ghosting problem (double vision) then tracking would help. HOwever your projector utilizes a single gun projector system. Think large screen televisions from 70's that had three different color lamps (red, green, and blue) and they shot onto the screen to form normal color spectrum) Your projector doesnt do that. A green or other color haze that is present eventhough the video is clear (sometimes its red or blue) is caused by a bad pin on the VGA cable used to connect the projector to its video source (laptop, DVD, etc). Each color is transmitted via a small wire inside the connector cable and each end terminates in a pin in the plug that attaches to the projector and the video source. Sometimes this is caused by a loose cable and can be reseated or otherwise the pin has become bent or broken at the connection point and is not making the proper connection for the other two colors. (Seeing green means that color is transmitting properly) Inspect your video cable for bends, kinks, or cuts. If there is no particular visible traumamove or adjust the cable to see if the problem is corrected. The Optoma series came with removable cables on some series and some had the cable attached permanently to the projector with only the end for the video input loose. If you have a detachable cable replace that first before diagnosing the projector itself. A new cable is obtainable from your local computer store for about 10-15 dollars if its standard VGA. If its a composite cable or DVI its going to be much more pricey. Take the cable with you at the point of replacement. Prior to replacing the cable try a different video input source, if possible, to insure that the source is not the issue.
I have the removable cable version. I had checked the cable earlier (as
it has been loose in the past), and even pulled it completely out of the
projector and the source (VCR) and put it back in to see if that would
make a difference. But, even when I pulled it completely out of the
projector/source, an extremely LIGHT blue color replaced the normally
DARK blue screen. .... Normally, the blank screen is dark blue (when
working properly with no signal input). But, now it is a very light
blue, except one solid green vertical stripe on the extreme right side.
This is when the video cable IS NOT plugged in. When the video cable IS
plugged back in with a signal from the VCR/TV, it displays the heavy
green haze. FYI,... all other colors DO show as well. But, they are over
layed with the heavy green haze. So, for example, the red DOES show but
is very faded, and the same with the other colors.
To be sure, I will go to Radio Shack tomorrow and get a new cable to
replace the existing one.
Can you think of what else might be causing this?
Fred, unfortunately the bulb wouldnt have an impact to the color LINES you see only brightness or lack thereof. If you have replaced with the proper bulb then the error lies in either the cable or the internal TFT LCD screen. The inside of your projector is very much like an old school overhead. The LCD reflects an image that is then magnified and projected onto a larger screen through the lens which increases size and the lamp which increases brightness. Without the cable being bad the only alternative for altered display is the TFT LCD or controller board internal the projector. From the manual you can change the display to black and white only to see if the line remains (the vertical one you mentioned) if it does then you have a TFT LCD problem for sure and the cable will not rectify the situation.
