Cramped picture Philips (Techniek Radio/TV)

Hello. I hope you don't mind that I'm writing in English.

I've been working on a Philips X20T731 TV (Chassis type F6) and it has a very squashed picture in the bottom half. The linearity controls can't solve it.

I have tried a new PCL805 (B407), no change. Cathode voltage measures 20.8V. The cathode resistor R914 is OK. Cathode capacitor C650 was defective, but replacing it doesn't change anything either.

What should I suspect?
