Remark
Pilot lamp Power cord
does not light (PI-4)
Fuse 3, 1.5A,
Midget fuse 2A
(P7-27, 28)
Power cord
socket
(P7-25)

Check whether Power cord would be
damaged
apparently, and be broken by a
tester.
Pullout both Fuses and check the
breakage. If so, replace.
Check Power cord socket whether would
be damaged apparently.
If so, replace.
Check the line voltage and the output
voltage on Transformer terminal.
If the output voltage could not be
approved, replace Transformer.
