Did you physically remove each module when you soldered the mother board? And, you did resolder the connections on the modules?
You shouldn't have to redo everything on the boards. It's just the high-current connections that flex and break
Sometimes, you can take some fine sandpaper and clean up the stakes on the mother board to get a better connection to the module.
When you turn on the set, do you get a thump sound in the speaker? That would tell you if the amplifier module is at least working. Examined the module for discolored parts?
You dont have a schematic, do you? The FBT also supplies power to some of the modules. Your no sound problem could be something as easy as a fusable resistor that is open.
Best of luck. I never really had alot of issues with these Maggie chassis, other than the module and mother board soldering problems, and the occasional tripler, and/or horizontal output transistor.
