McIntosh Tube Amp will not come on.

I have a fairly new MA352 integrated 200W tube amp/ SS Preamp. In the middle of the day, during normal operation, I powered it on, but the 4 tubes stayed orange. They will convert to a green "ready" state. The display just continues to say, "Tubes warming up." This phase of start-up lasts about 5 seconds. Now... It will not get past that phase.  Has anybody else experienced this with McIntosh tube equipment?

Same. Mcintosh picked up every call unlike nearly almost every other manufacturer I called.

One more thought; try doing a factory reset.  You'll lose custom settings but that may do the trick.

I had a similar problem, I held the power button down for too long which caused the tubes to keep glowing orange.
I had a technician at my home in Brooklyn within two days to take care of it.
