Question about ViewSonic PJD5122 3D Projector

Open Question

Viewsonic PJD5122 projector has a horizontal black bar through the picture

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.

SOURCE: Viewsonic PJ556d shuts down after 30-60 seconds

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.

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!

Why does my Viewsonic PJD5122 turn itself off after about 30 seconds of use?

Review your manual and check for a self-protecting power-off feature to prevent overheating. If it provides one, then you may have a fan that is out or became disconnected. Re-trace your steps when you replaced the lamp, you may find something that was not re-connected.

Green screen on VGA with Viewsonic PJD5122

VGA is separated analog signals in Red, Blue, and Green. Under normal cases, you'd be able to change the cable, source, or input port and resolve the issue. Unfortunately, if the green tint persists with all input ports on the projector (The two blue ones are Input, the black one is output. There is a potential that attaching input to the black output port could have caused the damage), different sources, and different cables, then it's likely a problem with the projector hardware itself and would require warranty service or otherwise repair or replacement of the projector. If you have an alternate way the projector can be attached, then try that (Such as SVideo), otherwise there may not be any good solution in this case short of checking the guts of the system.

Hello my picture seems to have shifted upwards ie the top of the image is now at the bottom of the screen then there is a black line then the next two thirds are above the black line. I think on an old tv...

The problem was not actually the tv the fault was on the satellite box. I unplugged the box from the mains to reset it and the picture was restored to normal.

White vertical lines in image w/ 2 inch black bar horizontal.

the black bar is from the light tunnel collapsing. the white lines are from the colorwheel or the main board has a cold solder joint. replace the tunnel and colorwheel and have the main board looked at.
