SYMPTOM Dead or tripping.
CAUSE
Line output transformer or problems in the power supply.
ACTION
Disconnect R632 and turn the set on.
If the HT comes up to 150V, then it is likely that the fault is in the line output stage.
This  could  be  the  line  output  transistor  (2SD1554  in  51cm  sets  or  2SD1546  in
59/66cm sets) or line output transformer.
If the HT comes up then shuts down again, it is possible that the vertical output IC,
IC501  is  faulty.    Sometimes  when  IC501  fails,  it  will  take  out  R501  (supply  reed
resistor).  Note that in this receiver, the vertical output IC obtains its supply from the
line stage.
If the HT does not come up, then the fault is probably is probably in the power supply,
IC701 or Q701 are suspect.  If either IC701 or Q701 are found to e faulty, change both
devices.
