I recently picked up a pair of Sea Wolf machines which between them hopefully have enough parts to build a single, working machine. I knew when I got into this that it was going to be my most difficult repair to date. I don't yet have the skill, expertise, or experience for board repair...my work thus far has been more around rewiring and all-out replacing bad component assemblies (power supplies, boards, etc.).
Anyway, I pulled the best parts from each and appear to have a complete game, plus a load of spares to swap in and out if I have problems. So, I crossed my fingers and flipped the switch...
The good news is that it does have signs of life. The front lights flash in sequence and the monitor lights up, showing garbage at this point. Just for kicks I swapped in the second PCB and had similar results, though the monitor essentially just lights up white with this one...no wavy lines or anything. Without getting too deep too quickly, I'm wondering where to start on this thing. As I said, I'm not yet up for replacing components or reflowing solder, particularly if I can potentially get this thing working with the right combination of boards. If I can't, then I'll start risking breaking stuff.
I'm looking for a list of dummy problems to check for before I get too deep. I'm thinking that I'll go through and thoroughly clean up all of the edge connectors, then give it another shot. On another note, the boards I have are different - I believe one is a version D and the other an E - anyone know the differences between the two, and all things being equal, which would be better to keep?
Thanks in advance for your patience!
