Sony KV-2100E vertical linearity problem

[shinvila]

Hello.

I have a Sony KV-2100E television with this vertical linearity problem.

The chassis is BE-2A and it doesn't have a service mode. It has some potentiometers, but none of them adjust the vertical deflection (Vlin).

Any ideas on where to look on the motherboard? Vertical deflection capacitors?


Attached is a video demonstrating the problem.
