I already fix it myself ! Need to open back cover, and on circuit board where power cord goes ( located on left side if you look from behind TV) it has power relay. Because contact in this relay little burned, that's why power circuit board and fan for lamp still on. Solution: open back cover , remove speaker, remove circuit board,open cover of that relay, clean contacts by fine sandpaper, assemble back and done! I made picture if anyone want it, send email to [email protected].
