Can anyone out there tell me how to access the service menu on a DVD/VCR all in one home cinema sytem LG LHCX245I.As well documented on a previous thread(LG Surround Help)I am unable to access the 5.1 speaker set up in audio menu to adjust volume etc.My guess is that the previous owner has adjusted the settings somehow and for some reason and I reckon entering the service menu may allow me to reactivate the 5.1 set up option in audio menu Any help greatly appreciated,
