Any Zenith experts around Los Angeles?

I'm tired of the jailbars on my Avante CCIII. I'm sure most here have read the threads I started when I got the set and many helped me with the restoration (for that I am very grateful), but the one issue I haven't been able to solve is the darn jailbars. There's nothing more annoying than watching a great image and then being hit with those darn light and dark bars.

I have replaced all the electrolytics, replaced suspect resistors, cleaned all pots and scoped all important points. The only true ringing I found was on the ABL, but was told by some here the problem was somewhere else in the set, but I've not been able to find it.

It seems most experts are in the mid west to east coast. I'm hoping there is someone on this side of the country that has experience with this issue. I could really use the help and am willing to pay.

Thanks!
