SYMPTOM Set will trip (re-boot) once the picture appears, if plug SA is disconnected from the
Dolby PWB the set will work correctly
Note:
Sound will only appear if By-Pass mode has been select in the Audio menu.
CAUSE
Dolby power supply not operating
ACTION
Normally this is due to R1721 and R1722, in the Dolby PWB power supply circuit
going high or open circuit.  However, a similar fault can be experienced if any of the
output IC's (IC1302, IC1303, IC1304 and IC1305) go short circuit, causing an overload
of the Dolby power supply.
NOTE
R1721 and R1722 have been changed in value during production.  Use the part
number listed below to order these parts.
