I worked on above set which was totally dead. Upon removal of the back cover I saw several obvious bad caps on the power supply AEP016-37. After replacing half dozen caps, reinstalled power board and to my surprise still had dead set. Removed power board again and went over with a magnifying glass. I saw rings around the solder joints on the outer pins of connector to main board. They all showed continuity, but I went ahead and resolderd the connections and the set came to life. Just fyi that may help someone with this set.
