My projector (viewsonic pj452) started flickering. When it started it would flicker once in around 5 minutes but now it happens many times in a minute. I tried resetting it from the menu and through reset option in the projector to no effect. What could be the reason and the solution? Thanks

The power supply needs to provide a constant current flow
to the lamp. Any small change or in the current will be seen as flicker
in the lamp and projected onto the screen.
Problem could be with low voltage power supply, the ballast or the
lamp it self is beginning to wear out.

How can I get a download for a PJ453 to my window XP


You don't generally need drivers for projectors. The projector should just plug in instead of a computer monitor.

Viewsonic Projector PJ557D "Screen Flip"


Check the power settings o nthe laptop, go to control panel, power options. see if its set to turn off the screen if theres no activity. I doubt this is your problem but worth a try. Going back to the viewsonic picture means its not getting a signal. So either the cable may be faulty which is less likely, or it is a software problem. Does the screen flicker on the laptop when doing the same thing (if the projector is not connected)?

Starts up looking good then in 3 minutes, all hell...


Go to the ViewSonic site and read through their knowledge base on your monitor.

Then once you familiarize yourself with electronics safety by reading through a basics manual once or five times, and once you've got it, open up the monitor cold and/or hot, and find out where they spilled Coca-cola down the back or whatever might be suggested by the ViewSonic knowledge base.  Lather, rinse, repeat; when the monitor acts right, then stop.

Image flickers


It sounds like the socket that the bulb goes into has an intermittant connection problem, or where the wires attach from the bulb socket to a plug or printed circuit board connection, or possibly a bad connection in the bulb driver circuit. Good Luck.
