how likely a thrown circuit-breaker does NOT show red?

The question comes down to: none of them shows red, none is clearly positioned differently from any other one on the board -- yet a circuit (upstairs) is dead.
What might be the problem?
How to troubleshoot it?
Thanks!

Tripped breaker, or tripped GFCI, are the most likely.

Breakers don't always give an obvious visual indication when they're tripped. The only way to be *sure* is to move the handle to the off position, then to the on position. If it moves easily to off, without an audible click, it was tripped.
Check and reset *every* GFCI in the house, including your outdoor outlets.
If the circuit is still dead, probably best to call an electrician.

This problem has been discussed many times in this group. Do a search. There may be a broken or burnt off wire somewhere. A loose connection. A bad circuit breaker. It could even be something as simple as a tripped GFI receptacle if it is a bathroom or outdoor circuit. You would need to starting taking things apart to find the problem beginning with your circuit breaker panel.

I agree. Just flip all the breakers off then on and see if it resets.
