I hate to break the bad news to you, but if your console was behaving one way before being reballed and now behaves a different way... the reball's gone wrong. My suggestion would be to first double-check mounting pressure, be 100% certain that you're only getting the red light no matter what you try, and if all else fails, flux under the chip, chuck the sucker back in the oven and hope that you didn't kill the CPU or GPU. The caps can wait, all things considered - your first goal should be to get back to where you started before things went sideways. IMO you might have eWaste on your hands, but it doesn't hurt to try.
