Well, I have replaced the fuse and it is still dead. I
have double
checked the PCB and I have found a part that seems to be charred.

I?m not sure what the big grey things are. I?d guess those are some
kind of resistors (labeled 2W10% 15K), but I have not seen something
like that before.
They are power resistors.
If so, the one horizontally in the pic seems to be
burnt. The PCB is charred underneath it, and no current goes thru it
accordint to my multimeter.
The little charring on the PCB may be conductive. I'd clean that off
first, before going any further.
