Check to see if the batteries are good. If the batteries are
good – check the cable connections between the Plasma
Display and the SPLITMUX Also, make certain the
SPLITMUX has power.
Check if the IR remote address is the same as the
SPLITMUX's address in System Setup menu.
Check to see if the OSD from the SPLITMUX displays. If it
does check the source selection and/or cables for the
source. If there is no OSD then make certain the output
cable is connected properly and the output timing of the
SPLITMUX matches the capabilities of the display device.
Make sure the SPLITMUX is not in standby.
Check cable connection. If connection is ok, check baud
rate and address of SPLITMUX

should not exceed 6ft. Some after market products can
enhance the length of DVI. Double check the specifications
before using these types of DVI cables.

the video sync is weak try using video selection instead of
Auto. Also, make certain it is not set for S-Video.

protected, check the Output Setup to make certain RGB is
not disabled.

and the SPLITMUX is not in standby mode.
Make certain the SPLITMUX input for RGB/YPbPr is set up
correctly.
