Wow, that first link is perfection! I'm worried though. The photo on that link shows the base grid green pattern looking VERY geometrically even with only the red and blue lines off. On my set, the green base grid geometry is off/wavy. Are the IC's the correct fix?

you dont need a service manual. the problem is the convergence chips and it has been plaguing these pioneers for years it is either the bad solder joints on the chip itself or the chip is trash anyway go to tvrepairkits.com and they will help you get everything u need

SOURCE: pioneer sd-643hd5 fuse issue
The fuses may not be your problem--I have fixed several of these---The large power board is on the right side as you look from the back?
Lots of these sets develop bad solder connections on that board--several sites on the internet offer to have you remove and send them the board to resolder--this set used lead free solder and after some years has problems--a few I have opened had clearly broken solder joints--I usually in this case remove the board(mark all the many plugs and make a diagram) and solder almost all of it by hand----usually fixes this kind of trouble.
I do this here for free so if this information was helpful give me a vote here....I am here to help people.
