I just don't want to replace every single cap "on the board that the yoke coil plugs into". I want to be more specific because I need to get new caps first.

I said that you will find perhaps a dozen bad caps in the set. Two dozen if you are very unlucky. I also said that you can fix the immediate problem with just a couple of caps in the vertical ouput stage and perhaps one on the 12v regulator. No tech who fixes these type of problems would need the service manual unless a trace was corroded away beyond recognition of where it went. In order to fix this set you need to: 1. Identify the leaky, high esr, and low value caps, which will require an ESR meter, a capacitance meter, and reviewing the instructions posted several time in the past for finding leaky caps. Google the group for Mitsubishi, capacitors, and my name for instructions on finding the leaky caps. 2. Clean the board of electrolyte and corrosive residue. 3. Repair the damaged traces and bad solder joints. 4. Replace the bad caps and perhaps the vertical output IC. If you don't check all of the caps for leakage you will be fixing it again in a few months. Now you have been given much more information than you will find in the service manual regarding solving your problem. You can spend the $$ if you wish.
