Moog Grandmother Power Component ID?

heya, i have sent my Grandmother to a service place here in norway.
it will not turn on at all. service man says a component having to do with the power transistor has burnt out. but he is struggling to find out what that component is.
does anyone know about this stuff? moog support is unresponsive after the company sale thing. Please help! :slight_smile: <3

the component in question is marked Q1, but the board has burn marks so we cant read further information on the component. anyone know what is it in detail?
