odd that yours would have defecated the bed, as they say.
Certainly could've been a static discharge, but the fact you've got lights suggests (to me) it wasn't a lightning strike.
One thing that does come to mind (and I know nothing about this particular tuner). Most FM MPX stereo tuners have an interstation muting circuit. It will "squelch" the audio if there is not signal above a certain threshold. Perhaps you have the muting ON and insufficient signal strength to unmute the tuner? Switch the muting off if you can (or switch to FM MONO, which usually disables muting) and tune it. See if you get anything (e.g., the "whoosh" of FM 'static').
Is the antenna (still) properly connected to it? if, e.g., it's 300 ohm twinlead, make sure the two 'legs' of the twinlead aren't shorted at the antenna connectors on the tuner.
The waning popularity of FM has made tuners (especially more modern/digital and mediocre ones) pretty much a buyers' market. You can probably pick up a decent one (locally) for less than repair will cost for the M-D if there's really something wrong with it.
all the best,
