Here's some piccies...

Anything there identifiable as a potential reset-causer?


In picture 2, at the back, there's a component lead just
visible with some charring of the circuit board. In
picture 3, it looks like a 180ohm resistor, but the leads
and board aren't visible. That could be a thermal/dry joint
candidate.


I missed picture 9 first time - It's R14, and it does look
like the board might be charred around it or the transistor
on the heatsink next to it (BD ?43B).

Need to see the underside of the board for any charring
and quality of the soldering.
