I have just installed a new Power HAT but at power up it sits there with L1 & L2 flashing every few seconds and does not respond to the buttons. If I press S1 & S2 together the leds stop flashing, but it still does not respond to button presses. I have another power HAT which works fine. Suggestions for a fix more than welcome!
It’s not even had a batter inserted yet, as I have "cracked off " the battery holder.
Regards,
Marc
