[HECnet] VS4000/60 power supply dead... or not?

Can you make a picture of the screw? Normal resistors are 0.25 Watt. Cut out the burnt one (15 k) and replace w?ith eight normal resistors of 120kOhms, put them in parallel. See what happens.

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. http://i.imgur.com/4hpUKpb.jpg 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. 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. On the other hand, I will have a stupid trouble: I can?t remove the PCB from the chassis, because one of the TORX screws is? well? screwed. The turndriver does not fix onto its head. I guess I?ll have to do a compraption taking a derivation from the (suposed) resistor out of the PCB. Unless there is any kind of magic for a broken screw head (and no, I can?t vandalize this one).
