I am having issues of a dead OFDM. In tracing things and trying to make sense of it I have found that the 5V on the main board is dead. I am supposed to get 5V at the test spot and pins 3,4 and 10 of the black OFDM/VPS cable but they all show dead or about 300mv. I just swapped bodies and I think I hooked something up wrong one of the many times I had it apart. I am thinking that maybe I burned up the 5V regulator. but I don't know where it is.
