L-R shading for me has ALMOST ALWAYS been the filter cap for the @200 V
supply. Its across all brands ! Thats hundreds of sets. Just blanking & video coupling caps were found a few times. IIRC there is one in you Sony.
As far as TNR / IF alignment go DONT DO IT ! When 17 yrs old my first TV
repair job I was told NEVER F with it or I will get fired ! He meant it. FAFO.
Yes there are a few traps you can do by eye but thats rarely needed.

Thanks Zeno.
I did observe the color bar requirement in the Sams when setting AGC. I didn't mess with the IF! I would not as I don't have the right equipment to do up right anyways and I'm not so bold.

Yes, there's a lytic cap there it's been replaced with the same value. C524, 4.7uf, 50V. I could swap it out for something higher I guess? Like maybe a 10uf.
Any ideas about controlling the focus voltage without loading down the G2? I thought maybe if I put a diode between the 530V and the 1M pot it could prevent that, but not sure if it's the right approach.
