Looking for your sage advices please!!
I have a genuine Raiden board which won't boot / no sound, I bought it as a faulty some time ago.
(I'm attempting to improve my capability to repair things and intend to release most of it back in to the community)
  1. Does anybody know of a source for a service manual with the PCB schematic shown?
  2. I'm looking to understand how to test well enough each of the chips / components... a number of the custom ones have been faithfully recreated by @caius!
    Is there a prescribed list of tests for each of the replacements for this board so I can rule them in / out for replacement?
  3. Would you suggest buying a working identical board to use as reference & to temporarily harvest parts for the fault finding efforts?
Once in every 3 or 4 power-ups I get this screen

I noticed this physically damaged resistor network (1038 1AM, 10K) which I've replaced already.
(In this state the first 5 resistors tested correctly, the last 3 were toast)

Any help or advice is greatly appreciated!!
