We have a Samsung Model txe2546 chassis kct52a which had no vertical sweep from the center up..Replaced the vertical output IC and checked caps in the vertical section..now the set is going into shutdown..Set is not drawing excessive current from the isolation supply so It doesn't look like a short. Relay will click on and then back off in a second..checked all diodes and caps ok ...even took the vertical IC out again but it still shuts down..Any help would be appreciated..
