Hello. Bought a SONY DA2400ES recently to replace my Yamaha and wonder if it is a bit faulty. (1) When i watch Sky HD through the amp with a HDMI lead the picture on the LCD starts to break up after a short while and becomes unwatchable , so i have to watch with HDMI straight from SKY to TV. (2) Also when the TV is on stand by and the SKY box is on stand by, the display on the Amp. starts to flicker LINEAR PCM etc. erratically. Can any one help? Regards Darren.
