Yup... leaking caps. Look at the staining on the copper traces around C7 and between C17 and that CPU chip.
Also, that 1/2 black 1/2 white part to the left of the transistor with the heat sink is the thermal fuse wrapped inside a heating element. That transistor with the heat sink is used to activate the heating element and blow the fuse. It truly is a module that can commit suicide.
