I have seen this topic is popular, but was wondering if I could get more advice. My blue will not move up/down only L/R. I read to replace the IC, and I did that, but not sure what resistors need replaced. It is still having the same problem so I must have a resistor problem. I noticed there was a bank of 12 or so resistors 6 each side by side and 2 of them did look discolored, but I did get a ohm reading on them. I was wondering if anyone knows what the value on those R's should be? I don't have any manuals, so if anyone could give me the most popular components that burn out causing a convergence issue and board location of the components I would greatly appreciate it. Thanks.
