I also had toruble with the Rebuild on the 1.6v xbox. The yellow LAD01 i think would not stick and so repetive attempts to get it to stick fail and it started looking bad in the area of the sodder point so i unsoddered all the wires and put it back together to see if it works and it still works. my question is.. is there any point on top of the motherboard i can attempt to sodder for the lads?
