SYMPTOM Reception of satillite broadcast not possible with certain types of LNB.
CAUSE
Sometimes when the VCR is powered up there is no LNB supply voltage.  This is due
to a combination  of component tolerance in the LNB supply regualator ( SAT PWB )
and the type of LNB load connected, which will operate a safety circuit within the VCR
causing the LNB supply to be removed.
ACTION
1.   Change R9543 ( Surface Mount Resistor ) too 1.2k. 2.   Add R9599 as shown in
the diagram. 3.   Add D9550 as shown in the diagram. 4.   Add a faom pad to the
underside of each component to prevent shorting. 5.   Cut printed track as shown in
the diagram.
