LCD Panel.
1. Use a dry cotton based lens cleaning tissue, bleached cotton
cloth, or lens brush to dab any large pieces of dust or debris
from the LCD panel
Note: Do not use any cleaning solutions as they may
damage the panel. Dust is easily removed with a dry lens
cleaning tissue, bleached cotton cloth, or lens brush.
4. Reassemble
1. Reinstall the LCD Panel Assembly into the projector,
securing the screw.
2. After the panel is cleaned always check the results
immediately after the procedure. Any time the panel is
exposed, it may pickup additional dust or debris. To check
the results, input the appropriate raster signal ( an all red,
green, or blue signal ) from a signal generator to the video
or RGB input. Inspect the projected image for any more
dust or debris. If dust is present, repeat steps 2 and 3. If
this procedure is done in a dusty environment, it may take
a few cleanings before a dust free image is present.
End of procedure.
