welcome larschr!
I've never seen a philips like that before! See what we miss here in the states!
As to the pincushion problem, I would look in the vertical section of the chassis. There is a pincushion transformer and related circuitry that corrects this problem. It could be something simple like bad solder joints, faulty caps, or a resstor that has changed value. Worst case senario may be the pincushion transformer. Best bet would be to locate the factory service manual and start troubleshooting (yeah, i know better said than done.)
good luck. I hope you can get it fixed.
