I have an Onkyo 515 AV receiver. It connects to a Panasonic HD Plasma TV, approximately two years old. It is connected by HDMI cable from HDMI out on the amp. An optical cable runs from the TV to the optical tv connection on the amp.
Also connected to the amp is a Sony blu ray player, an Xbox and a Wii. The wii is connected to the tv component fixings with an rca audio out into the amp. Blu ray/xbox connected via HDMI.
I have two problems I cant find a work around to.
1) When I turn the TV on the amp switches either to blu ray or TV/CD but displays no picture. I have to press tv on the tv remote to get the picture /sound. When I select blu ray or xbox on the amp the amp doesnt automatically switch to the HDMI connection. I have to go into the tv menu and press av then select HDMI 1 to get the reception. When I turned these devices off the amp does not return to tv, again i have to press tv on the tv remote.
2) Playing the Wii. I can get a picture just fine, simply select component on the tv and its there . But no sound. I have to go into the amps assign settings and switch audio to anything but optical 1, anything works but what the tv is assigned to. When the wii is turned off I have to reset the amp to optical 1 to get sound.
On my old sony amp none of these problems existed - connections are exactly the same.
