Since you apparently have been in there already and read the older threads, I'll skip the standard rant about not killing yourself etc - still, consider yourself warned.
As most of the time with these TVs, you will be looking at bad solders and/or bad caps. I wouldn't concentrate on the error code - I guess it was a good idea when the components were new, but nowadays it will usually be wrong or not recorded at all. The set shuts down as a safety procedure, and as long as it takes minutes to do that, most active components should be fine. Of course the controller IC actually might be faulty, and the shutdown another unrelated problem.
Clean up everything and with the set on, try tapping slightly around the circuit boards and see if you find a spot that responds somehow. There you might be close to some dry solder. It's usually just simpler to reflow them all though, and while doing that, replace the small electrolytics (there aren't actually that many on the main board) and whatever Die_Bogener recommends in the workshop. Problems with a single colour such as you see might be on the video output board as well (PCB3: check solderings).
One thing I think he didn't mention is the solderings / connectors at the deflection coils around the tube neck. They sometimes burn out. Good luck and be careful - the main power supply cap can easily hold its charge for a day or more!
