Yeti 1250 Power Switch Inoperative

I just installed a new battery in the 1250. Checked to ensure that all functions were operational. The Power Switch worked as did the individual selection switches. I powered it down and had lunch. After lunch I pressed Power Switch and the unit won't power up. The display works when chargers are attached and the display shows 100% battery. Puzzled since it worked before lunch, but not after - no one touched it.

Is there a main fuse hidden somewhere? All the observable fuses were checked and good.

Thanks
