Since you will have the iron out look for the following PC cons.
They are common to most sets.
PC at on/off relay, vert output ic, hoz drive transformer through
flyback, power supply area. Also in & out jacks & video outputs
on the CRT skt.
The line on the bottom is probably an electrolytic in the
vert just starting to go. Dont know about the int color, that
became a very rare symptom in later sets.
good luck
