Troubleshooting

Phenomena that may be easy to be mistaken for machine defects (continued)

• Although bright spots or dark spots may appear on the screen, this

is a unique characteristic of liquid crystal displays, and it does not constitute or

imply a machine defect.

• The projector may make a rattling sound when tilted, moved or shaken, since

a ap to control the air ow inside of the projector has moved. Be aware that

this is not a failure or malfunction.
