Probable cause
Corrective action
Adjust focus with the focus ring of the lens.
Set the projector at the correct distance.
Adjust "Tracking" and "Phase" on the menu.
Adjust "Brightness" on the menu.
Adjust picture quality on the menu.
Set the "Decoder" to "AUTO" or the correct
dedicated decoder.
If the problem is not rectified after setting to
"AUTO", set to forced dedicated mode.
Check if the signal is appropriate (scanning fre-
quency, etc.), and input the appropriate signal.
When the PC2 input terminal is being used,
"PC 2(BNC)" must be selected from the
"Options" menu. Set it correctly according to
the input signal.
Input separate sync signals for vertical sync
(V) and horizontal sync (H) signals.
Input signals with little jitter or skew distortion.
Use a TBC or a device with a built-in TBC.
Match the polarities of batteries correctly, as
shown on the battery cartridge.
Replace with new batteries.
Remove any shielding objects.
Use the remote control unit at a nearer point.
