Can anyone help with something quite strange that I can't figure out or see anything online regarding the problem! New Mac Mini purchased Friday. I have that into my DG820 AV Receiver then into my trusty Sony KDLV4000 TV. Everything looks great (apart from text being super small!) but when I change from say PS3 or TV back to MAC MINI on my AMP and wake the MAC up from sleep, there is a green tinge to the screen The only reason I am posting this in amp is if I quickly turn the amp off and on, presto back to normal. Any ideas?
