How to enter
To enter SDAM, use one of the following methods:
Press the following key sequence on the remote control transmitter: '0 6 2 5 9 6'
directly followed by the 'MENU' button (do not allow the display to time out
between entries while keying the sequence).
Short jumper wires 9631 and 9641 on the family board (see Fig. 8-1) and apply
AC power. Then press the power button (remove the short after start-up).
Caution : Entering SDAM by shorting wires 9631 and 9641 will override the +8V-
protection. Do this only for a short period. When doing this, the service-technician
must know exactly what he is doing, as it could damage the television set.
Or via ComPair (with the ComPair 'Tools' RC7150 Service Remote, it should be
possible to enter SDAM via the ComPair interface).
After entering SDAM, the following screen is visible, with S in the upper right corner of
the screen to indicate that the television is in Service Default Alignment Mode.
