HPPrinter M404n has been working normally. This morning the green circle and amber triangle are blinking. Disconnected power, waited 60 seconds, reconnected. Tried plugging directly into wall socket. Lights blink, HP logo shows, then screen is blank and printer does not start up. Could find no info in manual or online for this printer, and it is out of warranty. HP just suggested trying a different power cable. Has anyone experienced this? I'm wondering if the printer is dead, after only 16 months.

Remove the cartridge and try to start the device. You state that you plugged directly into the wall, has that always been the case or did you previously have it plugged into a surge bar or UPS? Using these devices can cause issues as the power drain of a laser printer can induce a surge protector to clamp down, effectively generating a brown out.
