So I've changed the 4uF decoupler, which is now 4.4uF which seems to have helped because I now have a stable picture of sorts (Attached, it does look a bit better in person)

I found a list of stock faults and it said no line sync could be either C4497 at 0.15uF, C2170 at 10uF or IC2001 which is TAA700.

I can't find any C4497 or C2170, but can find a C497 and C170, C497 is tropical fish capacitor but the one installed is rated 0.047uF according to a online calculator is 0.047uF (Yellow, violet, orange, black, red). C170 is 10uF in the set.

My guess now is maybe that me replacing the decoupling cap is that I've maybe uncovered a potentially incorrect repair, fitting a 0.047uF cap?

My question being now is am I right in thinking C4497 on the list is C497 in my set or am I looking in the wrong place? C497 is just above the line hold coil.
