First take the batteries out of both remotes and keep them out. Before you resit it . unplug the main, and wait 30 seconds and replug it in before resitting it.reset the main lift master. Make sure the screen clears. And please make sure you hold down the lift master reset bottom for 10 seconds. Then try it with out the hand remotes. Before or during a power outage it gives a surge. So it will knock out your main not your remotes. Also look at you electrical panel and see if it triggered a circuit to the off position.See if this clears the screen and restarts the lift master. If it does then replace the batteries in the remotes and try them separately. Let me know if that work Also Let me know what happens.
Power storms normally trigger the intake of the electric and it just needs to be reset. There should be no burn marks on your circuit board from a lighting storm?
it should not knock out your remotes. Now if your remotes broke with out a power storm that is a different story.
