Help Fixing Sony SSM 20N5U Horizontal issue
Hello everyone, im having some trouble with my Sony SSM 20N5U when i bought it has H-size problems i tried to fix it with service menu but all the menus related to horizontal are not working, if i change the value of H-size it does nothing, then i decide to do a full recap but that didnt fix the problem, i dont know where to search, also it has a white ghost on the edges i dont know if it is cause by the same problem hope someone could help me

Picture aren't ideal but I also see a pincushion effect, right?
Desolder L551 (or R561) and see if the picture shrinks or remains the same (very wide). If it stays the same you need to check the lower damper diode D502 and the capacitor in parallel with it C502. If it shrinks, it's something in an earleir part of the circuit: the coil, the resistor, the output transistor Q551 (the most likely culprit), IC552.
