Shrinking Screen Display

Our ViewSonic projector, which we bought only last May 2006 is having screen display problem. After only few minutes of operation the screen only shows 2/3 of the actual screen displayed in the computer then gradually shrinking. Can you please help diagnose the problem? Is this related to bulb? The projected is being used for 4 continous hours during Sunday only, for church service.

    we switch between the pc and video 2 or 3 times during our church service. We are having problems when we try to go from video to pc. Sometimes we have to push the button twice to get it to switch and sometimes that doesn't work. Last Sunday it took 6 trys, everytime we pushed teh button on the remote, the screen would go gray and then the video image would reappear. What can we do to fix this issue?

It can be a problem with teh bulb...you may want to make sure that the fan is not shutting down when you power off the projector becsue that may shorten the life of the bulb,...the fan should remain on for a while to continue cooling off the bulb....it probably won't hurt to have use another fan pointing to the projector while in use...

Computer screen on, Projector off

If you are running Windows 7\8:
Leave the ViewSonic projector on.
Right click anywhere on the desktop and select "Screen Resolution".
In the display column, it will give you an option to select your computer monitor, the ViewSonic, or to clone the displays.
Select your computer monitor display only.
Shut off the ViewSonic projector.

If you are running Windows XP:
The process is basically the same except you find the settings under Control Panel > Display.

Display Collapse

it is repairable but for the cost of parts and labor you would be better of getting a new 22" LCD monitor
for the problem I would suspect the fly-back transformer or power supply

thanks for rating

It worked beautifully last night with my macbook in a test run of my powerpoint, but this morning I plugged it in for the REAL presentation it didnt work. A bright, clear picture of the Viewsonic Logo...

you might need to turn off your computer .
then connect the data projector
and turn on data projector
then turn on computer
hopefully it detects the data projector is connected and switches windows to duplicate projection
On my P.C. F4 key in windows Switches the display manually to duplicate, alternate screen or pc screen only or projector screen only.
As I am not familiar with Apple this support article below might explain the switching of display outputs available on Apple Mac.

How do i reset the lamp hours? i just bought a new bulb and put it in

Press and hold the UP button on the projector for 5 seconds, this will display the Total Used Lamp Time. Press AUTO on the projector to reset the timer to 0. Wait for roughly 5 seconds for the On Screen Display to disappear.

ViewSonic PJ402D Projector does says searching for source, what does this mean? Laptop does not even notice that projector is connected to it as well.

you need to hold function down and press something like F1 F2 F3 F4 maybe twice to clone the screen display and make sure your projector is on vga and there is a secure connection between your laptop and your projector.

Viewsonic VX922 - black screen of death and the blinking (mocking!) green led

Really if this happens then you may want to contact viewsonic to see if it still in warrant. Reminder that most of their monitors have a 3 year warrany from the date of purchase. So make sure that you have your proof of sales/receipt/POP/invoice or what ever you want to call it ready. This model is old so they will ask for it if its a first time repair.
