My 2007-vintage ATV is in a bad way. It freezes up after about 5 minutes of use, and on reset the intro video has blotchy artifacts all over it when it plays. Since I don't sync media to it and only stream from my iTunes server I'm disinclined to think it's a hard disk problem, but maybe not? ATV Diagnostics do say there is a problem with networking but don't list a specific fault. I've done a factory reset & rolled through the updates, but it would seem the problem exists in hardware.
So my question is, is it cost-effective to track down a replacement logic board for it or just say hang it all and get an ATV2? I can't seem to find any links to purchase replacement logic boards, so it may well be academic in any case. Thoughts?
