HP97: Who was the killer (resistor or transistor)?

[teenix]

It looks like mechanical damage to me.

The resistor coil doesn't look burnt, just torn away from the central core.

There is also a scuff mark on the bend the left resistor wire.

Perhaps the PCB it was dropped or something dropped onto the PCB.

Possibly a repair job was attempted as there seems to be excess solder flux residue on the connectors below the resistor.

cheers
