Corona RDOD 0032

[nubleet]

had a board come in today with no power. Removed U5A1 as it was shorting. Replaced it with u5b1 and u5b2 from dead phat. 3.3v and 1.8v test good now. System powers on, "YAY!" I thought followed by a "BOO!" as the red dot 0032 showed. Reballed the southbridge and still yet 0032. Does this point to a dead southbridge or is there another solution?

*edit* board was virgin.

It have been fixed before by a reflow/reball of the XCGPU.

I did do a xcgpu reflow after I had posted this. I may try a reball. I'm assuming that the SB may have gone bad.

It could be a bad XCGPU as well.

have a different board that is RGH'd with demon installed. Retail nand throws 0032 but demon nand works fine? The other strange thing is... retail nand still boots and works fine with the error. Can't sync a new controller to it, but the one that is sync'd works. Oh, it also has an odde of a popular brand installed. I haven't opened it up to check the soldering because the client only uses the demon side. Anyone seen this before?
