we had a bad thunderstorm here about a week ago. I should have turned all my equipment off, but didn't, thinking the surge protector would do it's job. (dummy) since then, when I adjust the line level knobs to the right, the red standby led comes on with a "clicking sound," and then goes out. according to the manual, "it will also light up whenever there is a short circuit or fault which triggers the protection relays." what am I looking at here? any help appreciated, tho i'm not sure I want to know. thank you.
