Hello all Tiitronics said service manual is nla. Have a low resistance path from hot col to gnd. I opened hot & damper&still same. Looks like maby inside the horiz out transformer, but I don't have a diagram to trobleshoot this one. It has a strange circuit that looks like the real old zeniths with the separate horiz transformer feeding a high voltage transformer. I hate to go through a whole lot of trouble just to find that one of these transformers are internally shorted and also nla. Any help is very much appreciated .
