I have a cable box connected to reciever and was working fine for months, now i get no picture on tv only sound. I use hdmi cable out to tv that also uses my ps3 to tv which is working fine. What happened?

Have you tried connecting the RCA outputs on the cable box direct to your TV"s RCA's inputs?

Hello sir

Hook your Xbox to tv via HDMI, then hook TV to reciever through digital optical or composite cables. If you try to get your picture through receiver first, you may get picture and sound but, sound may be delayed and picture might not be the best. Bettter to run through tv first then provide sound to receiver.

I've posted this other places. Hope it helps.

My HT-S6100 had a similar problem with my DVD player and some times with my Cable/DVR box. The signal wasn't getting received at the TV. So, first I changed the input jacks my DVD and Cable box are plugged into on the receiver (e.g. from HDMI 1 & HDMI 3 to HDMI 2 & HDMI 4). Second, I reprogrammed the Input Assignments to match (e.g. HDMI in 2&4). Third, I deleted any Input Assignments that weren't applicable. For instance, I'm only using HDMI connections, but there were Digital and Component Input Assignments programmed in. When I say I deleted them, I actually set them to "----" (just scroll through the options and you'll find this.) Finally, I turn on my video/audio sources (PS3 in your case) and let them load/warm up before I turn on my Onkyo receiver. It seems to be working. Good luck.

If i am not mistaken you can select the HDMI signal going out on the 663, this means you should select to have only pictures to go out as sound will have to be reproduced by the 663.
So HDMI output setup on the 663 should indicate image only, no sound.

Make sure you have selected the HDMI output option in the PS3 menu, otherwise you will get no picture or sound, connect you standard cable to your tv first which came with PS3 to do this first.

ok your tv does not come with the very best sound, you have to get a receiver 7.1 or you can use the optical wire , that's if the system you are using has that option.

are you using hdmi leads and how are you recieving hd are you recieving it through a box
