OK i'm on TV number NINE,this is the SIXTH Sony HQ100. Here's the deal,first got the TV and switched on-perfect,spot on. Over the next few day's i've noticed the bottom left hand corner when showing reds is turning pink(like the previous set) If i use the TV's degauss circuit(on/off routine) it gets WORSE. If i use an external degasser it's perfect again until the TV is switched off & on again!! Heeeeeeeeeeeeeelp!!
