I had a similar issue with the TX NR609. Contact Onkyo. Mine was out-of-warranty, but they issued an exception and it was fixed for free. The technician told me that the company that made the HDMI board made ones that didn't last. New company has been used by Onkyo for the repair.

Hi Pablo the board you are looking for is only sold to Onkyo Authorized Service Centers so you would have to have the unit repaired at one of our service centers in order to purchase the board, Thanks, JT
Hi, there is no need for entering any serial numbers for factory reset. For hard reset press and hold VCR/DVR botton then press ON/STANDBY,secound later on the display should say CLEAR . So now you receiver is back to factory settings. If that works great if not try Firmware update for your model ,and if that failes
try unpluging all your speakers ,and try connecting your USB,CAB/STA or what ever you want(speakers unplaged). Btw dont forget trying different cabels. Last if all dont help you should contact ONKYO Servise/dealship.Hope ti helped you with your problem .
Your sound might not be working because the HDMI and optical audio inputs might not be working.
I made the mistake of buying the Onkyo HT-560 and in less than two years all of the HDMI video inputs started intermittently breaking. Sometimes when you selected the channel both the image and the sound would not come though.
Also the rear speakers stopped working from time to time and I have to run the setup again to get them to turn back on.
I am not sure that Onkyo was ready to introduce this technology, it has been a nightmare and my stereo is going to cost almost as much as I bought it for to fix it.
Oh and there customer service was no help, they just told to bring it to an "authorized service center for repair". They had also had no idea where there was one in my city it took them a day to get back to me.
The Onkyo HT-S5100 looks almost identical to the HT-560 not sure if they are different in anyway.
Stay away from Onkyo in the future! I know I will.
The problem is the hdmi board in the receiver .they are having trouble with the smd regulator and smd capactors that they are using on the board,they have updated the new boards as i have not got any back when replacing with the new boards. I have replaced at least 35 hdmi boards on this model. If you call Onkyo they will tell you that you have a hdmi board bad and take it to an onkyo dealer.
You will need to contact Onkyo directly and request the board from the parts department. I was not able to locate a part number for this as we are usually requested to perform component level repairs for these units.
We had the same red "pixilation" problem with our new Vizio 47" set. Read within this site for our solution (posted by Cavanaju): Call Vizio and have them come out and replace the LVDS cable and the main board. They will have to order and bring in the parts, which will involve them unscrewing a million screws to take off the entire back of the tv and replace that calbe within it all and the main board. It will then be just fine! (I hope...we just had ours fixed 4 days ago and so far, so good...) Hope this works. Seems to be a factory defect they have had with this set. Good luck!
Not sure if this is your fix, but I had what I thought was the same problem. I played with my Onkyo quite a bit ensuring the correct assignments for HDMI, audio and all that stuff. Turns out I neglected to make sure the output devices were properly assigned. Many devices aren't default to output sound over HDMI. I changed the audio out settings on the cable box to HDMI and suddenly the Onkyo worked great. I know, I'm an idiot for not checking that in the first place, but maybe someone out there is having the same trouble as well.
