I had a switching transistor and PWM IC blow up as part of a repair, where a big chunk of each went missing. Now I would like to understand the likely turn of events, and maybe determine if I did something stupid. If nothing else, I should at least extract some lessons from it.
"IC10" can be found on page 169 in the service manual:

The entirety of the repair is basically:
1. Device doesn't power on (IC10 supply voltage unstable)
2. Replaced C18 and C66
3. Device works...
