After reading many posts the problem I am having is a bit different.
Started with taking 10 power ons to turn on tv. Worked ok after each time. Then no turn on, code 22. Can hear the relay click and hi pitch, then power down. I have svc manual. Upon removing chassis, i saw that oil had dripped from chassis(not much), and traced it the 2 STK394 250's. Apparently they contain oil. (at least i hope its just oil)
--All 6 fuses (glass & pico) on PS and 1 on main board check GOOD .
--caps C9A72 & 73 on PS have tops popped slightly, board discolored under them.
