I have an option to purchase a broken TriCaster 850. It had a PSU issue (which was just replaced). From what I can tell now, either the Motherboard or CPU was damaged - likely by the power issue that originally damaged the PSU. What can I replace on my own to make this system work again in a way that it can be officially transferred to me? Iíve already sourced the identical parts, so that isnít a worry. This deal would be worth spending the extra $600 they cost, but much beyond that makes it questionable.
