Bought this tv last week, connected straight to sound system no issues , now when sound system is disconnected and you turn the tv on you get popping/cracking sound through speakers for first 10 mins then it disappears and tv is fine , if you turn volume off during this period the issues disappear, surely if this was , expansion and contraction issues you would hear it wether volume was on or off , surely this can’t be classed as normal on a £1300 tv , any ideas /advice?
