receiver now displays stb refsw and speakers don't work

Hi, thank you so much for the reply. I tried all the steps above prior to reaching out. I do have a x1 cable box.  In the meantime, I have learned that stb means set top box and ref means refresh. For some reason comcast sent something through the box that wiped out all the settings in my receiver. I thought it was an electrical issue, but it was cable that caused the issue. I have been able to tweak the settings in the receiver enough to hear some sound now and I have contacted yamaha to help fix the settings that comcast removed. What did comcast send through the box that caused this issue?

Of course, @amanda333! We are happy to help with any questions/concerns, anytime. There might have been a system update to the box itself, which typically will not cause any settings with your personal equipment, but it could have refreshed the entire setup causing the settings to clear out of the entire setup. Please share with us once you speak with Yamaha if you are able to update the settings to get better sound out of your speakers.
