Did you manage to solve your issue? Do you have logic probe like this this?

Crying ok so have it all back together and still the same.. have tested voltages at cpu,ram,vram amd roms.. all are at 4.97v i'm thinking one of the ula's maybe at fault... anyone know the layout of them or a replacement for them??
