After repairing this, set fired up with no vertical. On pin one of vertical IC LA7834, I have 8.2v coming from a zener. The odd thing is, as soon as I place my lead on test points, I see the required 12vdc for a split second, then it drops to ~8.0vdc. My 24vdc is OK. I replaced the 1µf cap, checked value of all resistors and all caps, but can not find any other problems. I adjusted the vertical p.o.t. with no help. This unit was manufactured for Sears, so no help from Zenith. What am I missing here? Thank you.
