When the power switch turns on,
the voltage of both ends of C623
repeats from 5V to 8V.
Check the following parts
C611, C624, C671, C672, C674, C6A1,
C6A2, C6E1, C6E2, D624, D671, D6A1,

R638, Q623, Q624, Q625, Q672,
ZD622, ZD672, T601.
All outputs are 0V. And when the
power switch turn on, the voltage of
both ends of C623 increase until
approx 10V, and become 0V
momentarily
.
Check the following parts
ZD6G1, C6G1, C6G2, F671, Q671,
R6G1, D6G2, C623, Q623, D623,
D625, D673, D6E1, IC621, IC671,
L6E1, PC621, ZD622, T601
All outputs are 0V. And when the
power switch turn on, the voltage of
both ends of C623 is within the
range of 0V to 10V.
Check the following parts
D602, R634, R635, IC621
Fuse F6T1 is broken.
Check the following parts
IC621, C622, C609, C610,
