Welcome back!
It seems that some CCs have a CUDA reset switch. Mine doesn't, but if yours has one, it's worth trying to press it for 20 sec, just in case. You may need a working battery for that trick to work. Read more details here and here.
Checking the area around the electrolythic capacitors or, even better, cleaning those areas with Isopropyl alcohol might help.
On the other hand, despite the 475 board bearing the same functionality of the 575, their form factors are quite different -- classic connectors here and there on the 475, big edge connector on the 575 (just like the CC)
