By now, you'd think the TV stations would have been able to finish repairs and get back on the air. Still, I'd put in a quick call to one or two of them, just to verify that they're broadcasting again. If they are, your own equipment needs a look see:
* First, try unplugging your converter or digital TV for at least five minutes, plugging it back in, and then re-scanning for channels. Perhaps a static discharge during the storm was enough to scramble the tuner's memory, but not bad enough to damage it permanently.
* If you have an outdoor antenna and it rained hard during the storm, carefully check the insides and outsides of all connectors on the downlead cable for signs of moisture incursion. This includes not only water itself but also rust or dark discoloration of metal parts. Also, check for visible cracking of the insulation. Water that gets in anywhere along the cable or connectors can cause a short circuit that will terminate signal reception. Replacement is the quickest and most inexpensive solution.
* If the cable isn't at fault, static may have damaged system components that rely on power to work. This includes the TV, converter box, any externally mounted signal amplifier or powered antenna (one with a built-in amp). Since you're getting something, sometimes, though, that probably rules out permanent damage to the tuner. Good luck!
