Note: To diagnose the set with ComPair it is not needed to
open the set entirely.
To access the ComPair connector, proceed with the following:
1. Manually unlock and remove the cover cap.
2. Remove the tape shielding that covers the ComPair
connector (1).
Note: Make sure that both the ComPair connector and the
UART connector are shielded off with a piece of insulating tape
after repair for ESD reasons. Place this tape over the holes in
the rear cover of the set.

The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By placing
a mirror under the TV, you can easily monitor the screen.
