Philips 28PT44060 (L01) - Pincushion issue

[Claustrofob]

Hello!
I'm working on a Philips 28PT44060 (L01) that has a "pincushion issue".
Service manual/Schematics are here, start around page 26:
Philips 28PT44060 (L01) Service Manual


Story is... my friend came over with his TV. He had no audio in left speaker. I plugged it in, but it had sound in all speakers. He had the wrong cable or something when he tested. I wanted to try RGB on it so I plugged in my Mister with the proper VGA to SCART cable (75ohm temination and such), turned it on. Nothing.... tried a few times and eventually it turned on, but now with this pincushion issue:






I'm suspect that this issue lies within the E/W correction circuit, so that's where I've been troubleshooting. I found a MOSFET (7400) that was bad between Source (+) and Gate (-), and I couldn't turn it on with the multimeter trick, faulty indeed.
This MOSFET amplifies the E/W circuit I think?

There's alot of good testpoint so I've been using my somewhat cheap portable oscilloscope to compare with these.
As you can see below, before and after the MOSFET swap the Vpp of L4 changed but schematic says around 12-13Vpp, I get 10Vpp. And from here I don't know where to look. The Gate of the MOSFET have 3.9V so it's almost at it's max which is 4V on the Threshold so it sure is activated. From what I can recall, after changing the MOSFET the pincushion was still the same amount. Maybe a tiny bit better so something else must be bad... and this is where I'm stuck....

And the S5 is also stronger now, that's the EWdrive signal that drives the 7400 MOSFET, it's around 1.5Vpp, should be around 0.5-0.7Vpp or something according to service manual.
There's no E/W correction or Parabola parameters in the service menu on this model.

As seen on the images above. I've been starting to replace a few caps that he requested.. I usually don't do full recaps but they all checks fine in the E/W area.

Here are the measurements:



Any help would be very appreciated and I have done alot of components test to verify the state that I can answer to later!

Thanks in advance!
