folks, i have an st60 and after reviewing these posts, i'm beginning to think panny has a problem. here's the deal. i just replaced my st30 with this st60. it should've been as simple as plugging in one hdmi cable and my back-up conventional antenna. weeks later with much frustration, picture and apps aside, this set is just weird.
the st30 was setup with hdmi/arc to a yammy recvr. worked perfectly. the directv box and bd were attached to the recvr's hdmi ports and the recvr's output was plugged into the st30's hdmi/arc port. life was good. everything played thru the recvr including the tv apps and the local channels.
it must've been too good.
this st60 will only output tv audio thru the optical port. no longer is there a special setting to turn off the tv spkrs. so now u get output to the connected recvr and the tv unless u turn the tv spkrs down. btw, they also eliminated hdmi/cec support for many if not all brands other than panny. so have fun juggling your remotes or plan to buy a uni. for those who use directv, there is a workaround. the directv remotes have some support for recvrs and can be configured to control volume without having to constantly play with the slider at the top of the remote. u can configure av1/2 to operate your recvr (vol) and use a 2nd code (993) to make it the default device for volume. instructions are on the dtv settings menu.
bottom line, it appears that panny has a problem with arc. i do hope someone's patient enough to call it in. their helpless desk ppl can be frustrating.
