Hello,
First try to darken it
1. Press [2nd] key and release it.
2. Press [UpArrow] and release it.
3. Repeat steps 1 and 2 in sequence until contrast is adequate.
Do not stop after 4 or 5 cycles.
If that does not solve the problem, the main batteries may be drained, and need to be replaced with fresh ones.
Hope it helps.

The screen went dark on jmv 111


Dark as in gone or dark as in the image is still viewable?  How does the onscreen menu look when the image is dark/gone?  If the onscreen menu looks right and the image is still dark, you might want to check the cables or another input.  If another device using different cables and another input looks fine, you may only have a problem with the input/cable you are using to view the movie.  If the onscreen menu is also dark, then I would think there is an internal problem that needs looking into.

Really dark (not usable) screen


The backplane power supply, and or the backplane lamps are probably dead. In some models these parts are replaceable. In most of the models, the backplane lamps are an integral part of the screen unit, and cannot be replaced without changing the complete screen unit.

Call the manufacture tech support to find out where you can send the set for a proper service estimate.

Viewsonic Projector not displaying RED


Hi there

This could be a problem on the Mainboard - because all the proccessing from your inputs is done on the Mainboard.

Try replacing it , I'm sure you'll have joy then.
