I may just give up on it if I cant source a diagram and use it for spare parts?, Which is a shame because its a very clean little set. BTW. The CRT is Panasonic.

I have been looking at the TA7698AP Video-Chroma-Deflection chip data and think I might just replace this as they are relatively cheap. It does all the chroma processing and H & V deflection. It may make sense since I had Hor lock fault and then vertical jitter. And then the chroma died. Now I have data sheet it might pay to check supply rail voltage.
