Yamaha TSR-7790BL Unresponsive, freezing up...
I have been having issues with my Yamaha TSR-7790BL (firmware 2.60). At first it started out as being issues with the remote control. So I would use other remote controls and then whenever I needed I could always use the App on my Android to act as a stand-in. So, the other day I decided to re-calibrate my speakers because of a change that I made to them. I was able to do 3 positions but then it would not let me finish. It was unresponsive to both the actual remote control and to the remote app. So I rebooted the receiver and tried again. This time it only let me do 1 position and would not finish. I tried so many times, with so many default resets and the whole time I could never use the remote control. It's as if it had stopped altogether. Of course I checked and replaced batteries using a meter to verify that they were good. So then I decided to reset the receiver back to factor defaults. After that the remote control still would not work, and, as you can imagine, neither was I able to control it with the app anymore because the receiver had lost its WiFi connection. So I ended up plugging the receiver into an ethernet cable and eventually got control over it once more. I tried several times to run the auto setup with the mic and every single time no matter what I could only do 1 position and it would not let me click the "Next" button to move onto the next position. I also tried using the single measurement option and it would not let me click the "Finish" button.
So then I decided to re-flash the firmware (2.60). I downloaded the latest from the internet (ver 2.60 - same as before), put it on a flash drive and began the process. I noticed it erasing sections of memory and then writing back to it. After it came back up I still had the same exact issues as before and that is where I am today.
Has anyone seen anything like this before?
