After replacing the fuse, the system can be started with a series Lamp of 100w. Then ic(s) can be checked for temperature/heat generation and voltage drop to locate the fault.
Yes ... Thank you for pointing out... That method make more sense.... rather then destroying pcb traces...but sometimes it's better to check for fault in no power condition to avoid farther damage...
