Color classic crt pots problem

I am restoring a Mac color classic. I recapped the logic and analog boards and the Mac is now booting and operating like new, but I have no response from mostly all the pots for horizontal screen adjustment. 
HW / horizontal width

PB / pin barrow

KS / keystone

HS / horizontal shift

they are all somewhere related as they affect the horizontal adjustments.

I cleaned the pots, and they are turning easily as they should.
I double checked the caps, traces and tested the contacts, and everything seem to be normal. 
is there a specific area I should focus on 

On the board? Also the board at the back of the crt seems normal, no loose soldering...

anyone with something to suggest, I would appreciate. 

 
Hi, I realise this topic is from forever ago but I just did an analog board recap and hit a similar issue where PB, KS (probably others) stopped having any effect. I fixed it though! After I double-checked that the pots themselves were still good, I realised the problem was probably one of the caps I had replaced, so I put the original CL21 back in and it was all fixed!
