Here's a couple pictures of where I located the 1.5K on the back side of the circuit board. It's between pin 4(ground) and pin 10(input to G1 gate which is IC 9 in the manual). You will need to adjust the Vertical Blanking Width pot(R35) in order to get the best line pattern at the top of the picture. Basically you will be adjusting the width of the vertical blanking pulse, which determines where at the top of the screen the horizontal scan begins. When that pulse is too wide you see the vertical blanking pulse turn off transistion, which is what causes the wiggle in the vertical lines. Hope that makes sense. Let us know how it works out.

Mighty big THANKS!!! I fought this unit for days and finally gave up! It sat in my upstairs room for a while now!
I wonder how many other people have given up on one of these because it just didn't make sense! Again, Thanks!!!!!!!

Cool. And you're very welcome. It's always good to know that the fix works on more than only my unit.

Your Sony has way better vertical linearity than my Philips.

That Sony was saved from the street! It had the remote taped to the top. I like it because it is a mono unit with video in. It works great with my SL-2000 Beta portable.
I always got a chuckle out of Sony's cabinet colors! Again, thanks!
