Ok ,1st I have 2 front JBL speaker with low & High Frequence on it and a central speaker. When I level up my sound up to 37 the recever is closing itself and the stanby light is flicker. Its doing that on DVD,VIDEO 2(my sound tv).. I tried to change the style of listening and no results. All is correctly connected and I hear sound but the receiver is closing itself up to 37 or 43 depends if its a DVD or TV
