The Wells Garder U5000 in my Star Wars Trilogy started having problems a few weeks ago. The picture started waving and was expanding and shrinking. When I opened up the back I noticed a fairly loud buzz coming from the flyback. Well I figured I either had a bad flyback or that it was a cap issue.
After replacing all the caps on the chassis and neckboard (except for the large 400v cap) and installing a new flyback I am still getting the same symptoms. Now along with the wave and buzzing half of the screen is also dim. I have added a picture....

My U5000 chassis had a black wire jumper going from W193(which has been removed) to R812 (which has also been removed). I removed this jumper and after adjusting B+ to 117.2 V (at TP202) I now have a full and stable picture. Can someone please tell me if this jumper(W193) and resistor R812 were supposed to be removed ? Should I put them back in ? This chassis has had the WG recommended mods done to it by the previous owner.
