E750: No power to the Generator board
Updated: 06/16/2017
Article #: 86
This message is signalling that the Generator board (A10) is not powered.
Check that if LED H3 of the Generator board is ON; in affirmative case,
check connector X53 insertion and insert it correctly. Check the voltage
between TP21 and TP22; it should be 10 V DC ± 2 V; if the value is inside
the range, replace the Generator CPU board (A9). If the value is zero (or
very low), replace the Generator board.
If LED H3 is off, perform the appropriate operations as described in the
previous chapter.
