Intermittent horizontal deflection
Resoldered the pins of horizontal deflection transformer
Picture is horizontally narrowed and deformed
Capacitor C2913 (390nF, 250V) on the deflector PCB had lost capacity
Geometric distortion, Pillow, and picture enlarged horizontaly
The problem was a short from GND to pin 11 inside IC301 (TDA8350Q). This pin is the output of amplifier for geometric correction signal. Replace IC301
Just follow my advice to look for an expert to settle down your problem. I hope you can find a good technician to replace the given tips to prove my expertise does not good enough information I give but it just too simple to follow rules.
