Default Panasonic viera audio problems

Just picked up this new plasma from best buy and am having issues with hdmi audio. I hooked the tv up initially and had audio and video through the hdmi cable. After shutting the tv off, the audio would not come on through the tv speakers or the surround speakers. Geek squad provided free hookup with the best buy package that I rec'd so I thought I would let him deal with it. He "determined" that I prob. had a bad cable or a bad dish network hd reciever. I replaced both and continued to have the same problem. Called panasonic tech, they walked me through audio setup, were unable to help and offered to send out a tech. I declined and said I wanted a new tv. Best buy brought me a new tv....however, I am still having the same darn problem!!!!! Sometimes hdmi works, but after shutting the tv off and turning on i lose audio. To get it back, I have to turn off dish, unplug hdmi cables, stand on my head, bark like a dog, cuss and swear, and sometimes it will work. Otherwise I have to get sound through component cables. Geek squad guy came back and said he thinks it has to do with the "handshake" that has to occur between the hd reciever and the tv itself.
Anyone out there have any advice....I would much appreciate it!

If we can get the exact equipment being connected we can possibly help further.

Many surround receivers have issues with HDMI. The time they allow for the TV to reply is too short. I'd try connecting the Dish receiver directly to the TV to see if it is actually the surround equipment causing the issue. If so, then you could run the optical audio from the dish receiver to the surround system.

Default tv name

The model I purchased is the TC-P50G20. I have an hdmi connected from Dish dvr duo reciever to to tv hdmi1. I have a panasonic blue ray home theater SA-BT228 connected to the hdmi 2. I have an optic line also connected from blue ray sa-BT228 to back of tv. I have a 5 colored component line for a WII hooked into back of tv but not hooked into WII. Currently, I do not need an audio component cable to get sound. I monkeyed around with unplugging and resetting and have sound through hdmi 1......however, i have not shut it off since I have got it to work through hdmi 1. Tomorrow morning will tell the tale. In the past, if I leave it shut off for a while, it acts as if it has fogotten how to communicate with the dish reciever and the only way I can get sound is by running it thru the component cable. Also, b4 I got it o work today, i shut the actual tv speakers off.
I also have to say that i always have gotten (audio) hdmi 2 to work thru the blue ray....which leads me to believe that there is some mis-communication between dish/hdmi/tv.
Let me know what you think....i fix people....not tv's!

Default viera link

I tried hitting the viera link button and it was already set to "tv". I have tried turning the tv speakers on and off and that does nothing! HOW FRUSTRATING....ITS A FRICKING WIRE THAT CARRIES AN ELECTRICAL SIGNAL.....WHY DO THEY HAVE TO MAKE THINGS SO COMPLICATED.....UGGGGHHHHH! $1500 for a plasma/blue ray/ and home theater and I cant get it to perform optimally because the tv cant "hear" what the satellite is trying to tell it?
I do appreciate everyones advice. Like I said, I can get sound by using a component cable.
Also, when I watch a blue ray, I do get theater sound (I have no issues with hdmi 2....which is my blueray home thx input).
This leads me to believe that it is something between dish reciever and panasonic tv. Am I right here????
I have already replaced the tv once and the dish reciever once. I just want to get this working. Panasonic tech support has not been able to figure it out. Maybe I will call them again and get someone more knowledgeable about this issue.
Thanks everyone...and keep the advice coming....

Joe

After not working all morning, I shut everything off and went outside to do some work. Came back in, turned the tv on, and !BAM! There is now volume coming out of the tv speakers! It's magic! I am sure it wont consistantly work, but its working now? What gives. Any one have any ideas what to do here?

It IS a handshake issue, no doubt.

If you hook the dish to HDMI 2, do you get the same results?

Default problem

I've got a 58" V10 Vierra, with the VIP722k HD receiver from dish (hooked through HDMI). was working fine for a number of months. All of a sudden, turned it on one day, and no audio. Messed with it for quite a while, and determined it's the hdmi port on the receiver. 3 receivers later, and still having the same problem, I called panasonic. They said it's a known problem, and they've been getting tons of calls on it. They said that the most recent firmware pushed to the DISH receivers have issues with the HDMI handshake, and they have notified the engineers at DISH. So I again called DISH, and the rep dug in some of their in-house information, and did locate the issue....so they ARE aware of the problem. So, i'm assuming a fix is in the works! Until then, just use your HDMI for video, and connect RCA cables for audio. You can tell the TV to use video1, video2, comp1, etc for audio for each HDMI port.

Make sure you turn the TV on FIRST and change to the correct HDMI input for the source you want to watch. THEN turn on the source device. THAT is how you make sure there is no HDCP handshake issue. Many cable/sat STB (Set-Top Box) do not properly continue to do a handshake and if the TV is not on and on the correct input the STB will not allow for signal to the display after that without turning the TV STB off and then back on again.

Default thanks guys

I had a feeling it was a dish reciever/tv handshake issue. That is what the geek squad guy thought. Since the panasonic blue ray gets audio through the hdmi and I have tried the other hdmi ports on both viera tv's when using the dish without any change.
I am glad that Dish is working on the issue. Hopefully dish can remedy the situation.
I will keep trying everyones suggestions....I appreciate everyones input!

Joe H. I have the exact same tv and Dish DVR and have the exact same issue. Very frustrating. I have my DVR going in through component 1 and also HDMI 1. I also have optical digital out into my amp for sound. So if my wife is watching a show and doesn't care about surround sound, she can watch it on component 1 and get audio that way. If we are watching something from the DVR where I want the full effect, I can get my video though HDMI 1 and turn on my amp and get the 5.1 audio. Either way glad to see someone else out there feeling my pain.
