Question about ViewSonic PJD5122 3D Projector
There is a "blacked out" line through the top third of the picture. Everything else is perfect. Replacing the bulb did not fix the problem. It happens all of the time whether or not it's connected to a computer.

This is a common Mainboard problem on Projectors , unfortunately the Board will either need repairing or replacing.
No shortcutts on this one !

My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.

2 issues- the light filter on one of the lcd panels is burnt due to excessive dust and heat. and one of the lcd panels is shot. time to replace the entire optical engine, unless you can get the prism assembly. otherwise, replace the projector. if you do, remember to keep it clean.

Testimonial: "Thanks for the help. Looks like the trash for this one!"
It seems problem with DLP Chip in projector that generates image to be projected. DLP Chip will be replaced by professional to fix this issue . I'm afraid it is not user level repair nor it is some sort of wrong settings in menu of projector.
It is hardware problem and professional can fix it. Please check with nearest tv repair shop or ViewSonic service center for fix.
Hope these info will help you.

SOURCE: I have my computer on
Assuming that you have all the connections between your computer and the projector already performed, you should check in you computer's manual what is the key combination necessary to switch between normal mode and presentation mode.
For instance, some Dell laptops and computers need you to press the function key (key marked with Fn in blue) and, while keeping it pressed, press also the F8 key (marked with CRT/LCD in blue) to cycle between the options.
Some HP laptops and computers will need you to do the same operation, but now using the function key and the F4 key, to select between "Computer only", "Extended (dual) presentation mode" or "Projector only" modes.
Some computers have an icon in the tray area at the bottom right part of your screen for the display characteristics. Clicking on it shows a menu where you can select the graphical options for your computer, and there must be an option for the selection of a dual display mode through which you can select computer + monitor (projector)
This same function can be called from the Control Panel in your computer. Assuming that you are using Windows XP, you will need to go to Start > Settings > Control Panel > (Graphics Adapter Configuration Setup), where (Graphics Adapter Configuration Setup) will depend on the graphics adapter chipset used in your computer (Intel, nVidia, ATI, VIA, etc). There, you might have the same options to select a dual presentation mode, to show the things in your computer display and/or your projector.
If even with these indications you are still not able to make your computer show its information through the projector, please send us more details on how you connected your computer to the projector, as well as the brand and model of your computer and the operating system you are using.
Hope this information can be helpful!
