Well Ive had this receiver for 4 years no issues suddenly one day out the blue it wont display WII video and the Onkyo on screen menu. I get a message cannot display please change resolution on TV. The TV is a Samsung Plasma PN50C550. the TV is hooked by HDMI to Scientific Atlanta 8300 HD cable box and the cable box to the receiver. It worked all fine but now i just don't know Ive checked setting its OK. All other works fine PS3, ROKO XD, Broadcast Cable. The stuff that displays at 480P seems to be the problem the WII settings are on 480P. When i connect Wii directly to TV HDMI it displays fine. I don't know if the chip is not changing to the lower resolution or not. Anyone ever had an issue like this or any ideas.
