Eat/west output transistor
 RH-TX0151BMZZ
Open or leaky – SMD
R519
Ramp charging resistor
VRD-RA2HD104J
Goes high or open – on component side of PWB
NB:  L603 and L604 fitted to the 66GF63H are different to those shown in the list above. L603 -
RCILP0262BMZZ and L602 - RCILP0294BMZZ.
Notes
  The component list above shows the various component part numbers for parts mentioned in this Technical Bulletin
- it is not a list of components to change for east/west or geometry problems.
  IC801 can either be a 3120 or 3130 - please check before replacement.
  D516 is not shown on the GF circuit diagram, although it is fitted to the chassis.
  R519 is sometimes a 150k
 resistor, check the value before replacing, as fitting the incorrect value will result in
poor east/west geometry performance.
