Perhaps this:
Symptom:
At turn on the raster appears and rapidly changes colors. Then shutdown
(protection) happens. If placed into Factory Mode using the 4835 310 57511
FMR remote the flashing will continue. Sg2 voltage is stable and clean of
disturbance.
Cause:
Open resistor 3451 and shorted diode 6447. 3451 is a stand up resistor and
may be measured in-circuit. Normal value is between 2 and 10 ohms (varies
with model-see Force).
Parts are on top of board at Section 6B.
Resolution:
Replace 3451 and 6447. NOTE: 3451 is a critical Safety part and must be
replaced by the exact part/value.
