This TV have also AKB. I deactivated it and the picture is very Red, so the AKB has reached its limits. Definitely the tube is very old. Somehow I can understand Sony's policy back then to shutoff the TV past a certain point.
I tried to boost the heater voltage by about 30% but that did not change anything. I read somewhere that not all tubes can be boosted that way.
I ended up dismantling the TV to keep the PCB as spare parts and the yoke and magnetic strips. The good news is I just found recently in my neighborhood someone selling a very similar model TV KV29-J MF1. The tube is still in very good shape, the convergence pretty good. I just had to apply 2 magnets to correct the geometry and I was good to go.
It was a good learning, thx for all the tips.
