What did you do to turn the 120 back on? Did you turn the inverter on or turn on the power from an outside source?

It appears to me that now something is severely limiting the 12V power available to the 12V circuits in the coach. If the buzzing of the inverter is consistent with the 12V lights flickering I would guess your battery power is limited in getting out of the batteries and into the systems. My best guess is that your coach batteries are depleted and the merge isn't working. Check the voltage at the house batteries and then on either side of the merge solenoid both with it on and off.

Thanks Jon

I turned the power off at the electrical panel in my garage, an outside source. I cannot get the door open to turn the merge switch on at the dash. I will check the house batteries but am pretty sure they are charged, everything was working fine until this morning, when I changed the merge solenoid.
