Radion G5 xr30 blue all green lights

Hello.
In one of my lamps, when turned on, the buttons light up red for a second and immediately switch to green. This is accompanied by a faint clicking sound inside. Then the lamp does not respond to buttons in any combination. Temporarily disconnecting the button cable, wi-fi module and backup battery did not change the situation.
Has anyone encountered such a problem? How did you solve it?
Thank you!

By rearranging the working modules from one lamp to another, I was able to find out that the problem was in the LED board. Two contacts of one of the connectors have oxidized due to exposure to salt.
