5.8.10 Power Supply
In case of no picture when CSM (test pattern) is activated and
backlight doesn’t light up, it’s recommended first to check the
LED drivers on the PSL(S).
Attention point for cable handling: (dis)connection for power
cable (power supply <=> SSB) should always be executed
without any bending or mechanical stress on the outisdes of
the connector 1M90.Risk of double pins inside the connector
should be avoid in this way.
5.8.11 Display option code
Attention: In case the SSB is replaced, always check the
display option code number (group 2, first option number e.g.
“44855”) in SAM, even when picture is available. Performance
with the incorrect display option code can lead to unwanted
side-effects for certain conditions.
Also supported in this chassis:
The display option code can be changed by “062598 HOME
XXX” special SAM command (XXX=display option in 3 digits).
