Subject: [TechAssist] Samsung color tv Model txe2546 chassis kct52a
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..
