•When unit doesn’t power ON and fuse F103 is
blown, it is necessary to find out the shorted
components before replacing the fuse and turning
on the power.
•If F103 is blown it is very likely caused by shorted
MOSFETs at one or more channel’s power output
or may be by shorted on Q1101 and Q1102.
• If -7v was shorted, the master clock will be
missing also.
