connectors are correctly matched.
❏
Ensure the pins on the cable connectors are not bent or broken.

Open the on-screen menu and select adjust picture > Color

Open the on-screen menu and select help > Diagnostics. Run

Reset the picture settings to the factory-default settings. See the
following problem.
❏
Reset the projection settings to the factory-default settings. To do
this, hold down these three buttons on the projector for 5 seconds:
back + up-arrow + auto sync. (This does not reset network
settings.)
❏
Certain high-definition digital sources incorporate HDCP
(High-bandwidth Digital-Content Protection) content protection.
Such content cannot be displayed by this projector. If the device
has another output port, such as YPbPr, try connecting that port to
the projector.
❏
If you connect certain types of VGA monitors to the VGA output
port, it might have a blank or erratic display for video inputs, but
it should have a good display for computer graphics input. If this
occurs, trying using a different type of monitor.
❏
If possible, turn off the projector. Then turn the main disconnect
switch off, wait 60 seconds, then turn it on again.
