Look at the ballast module. It controls the lamp operation.

Lamp light flashes amber without the lamp ever turning on, then projector shuts down in a minute or two


Based on what you're describing, it sounds like a failure in the lamp ballast itself. The projector will probably need to be sent for service.

If you have a spare lamp, that would be the first thing to try. However, if it isn't that, it is likely the ballast.

MY VIEWSONIC PJ402D DLP PROJECTOR WILL ONLY DISPLAY IN BLACK AND WHITE.


Hello,
If you are connecting the projector to the signal source via S-VIDEO cable this not uncommon. It usually happens when one of the connectors or the cable is broken. Try a new or different cable. If problem persists examine the connectors on both end of the cable and the one in the projector as well as the one in the signal source(pc, laptop etc) to see if there is a hardware fault. If all is good then the problem is internal with the S-VIDEO connector. In that case your other option is to use VGA.
Have a good day, hope this helps.

Hi. My PJ402d is already secured to laptop but keep sending the message "searching for source". What can I do to obtain my power point correctly?? Thanks for advices.


disconnect cable from the projector end. Then connect the free end of the cable to an LCD monitor to confirm that the video is coming out the laptop and out the same cable.

Then reconnect the projector.
press the source button until the video appears

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.
