Electronic clock stops working after a power surge

Hello! :) There is a Scarlett SC-4003 Alarm Clock, it doesn’t respond in any way, it’s not a radio, it’s not working. The night turned off the light for a second, the light blinked, it seemed like a power surge, and in the morning the clock stopped showing, maybe this was repeated during the night, because the clock did not immediately refuse to work. There are 16 v 220 mf + 105 ° capacitors in the watch’s microcircuit, two of them are the largest and they have a “plastic” sticking out where the contacts come from, as if they swell, ring them, one rings without stops, shows the numbers and stops, but the squeak does not end, and the second freezes on one digit, which means a breakdown, I think. The board smells of burning, weak, you need to sniff, it is not clear what exactly. Could it be only in capacitors?
