Last year i delivered a pair of speakers to a customer, and connected them to his BeoMaster 7000 that was taking a feed from his new Pioneer Plasma screen.
All through my install, he was singing the praises of his new screen and his new Sky HD box. He turned it on, and to be honest, the picture was pretty awful. I didn't say anything though as it may have looked like sour grapes that he didn't buy a B&O screen.
He told me the installer, a young man, had done a wonderful job of hiding the cables - but seemed a little unsure about the connections. He asked me to check if everything was okay. I politely said it really wasn't my job to judge others work as i'm not a qualified installer myself, and that was the end of it.
However, upon packing up my things - i took a little look on his Sky HD box settings when he went out of the room. 1080p output, check... 16:9 format on the output, check... Plasma screen, so contrast on medium (my personal preference), check... Hmmm.. all seems fine, but still a rubbish image on BBC HD and Luxe TV (the best channels for HD).
It was only as i put his remote back on the stand/cabinet and peered round the back that i noticed there was no HDMI cable... nowhere! The Sky HD box was connected to the screen with a SCART Lead !!!!!! 😂😂😂
My 'blooper' was very discrete. I mentioned that 'the installer really needs to be called out to check the cabling he has used. He may wish to reconsider which connections he has chosen' and left it at that...
