Ugghhh Fredo! That sucks. My 60gb brick had YLOD too. Agree with you - pain in the ass. I took mine apart, only to find it wasn't just the usual overheat fixable as BmF8 mentioned. Board was brown charred in multi locations. Bought a new 1.
better than paying over $120 and waiting a week or 2. all you need is a heatgun and thermal compound. Ask your friends & family for the heatgun, if they don't have one then its $60-$70 for good cheap one and $10 for thermal compound. DO IT!
