Hi, I have a problem with my Onkyo TX-SR876EU amp.It didnt switch on unless you take the plug out then push it back in approx 5 times then all of a sudden you hear some electronic tick sound and it comes alive. to avoid this happening i left the amp on when turning everything else off.It was going fine then tonight all of a sudden the screen froze on the tv, sound was still playing and you could hear in back ground noise of me changing channels.I tried a Dvd it was fine for 20mins then froze when switching back to sky it had the same frozen screen of the sky channel i watched before dvd.I switched the amp off thinking i would have to do the 5 or so take plug and put in but is not turning on at all now.Any ideas and Help as to whats wrong will be massively thanked.
