I had lightening strike right down the road, about 1,000 feet as a bird
flies.  It took out some stuff at my neighbors, including a freezer
which died a month later.  It even blew light bulbs, I mean literally
blew them.  They exploded and glass went all over the room.  I suggested
surge protection for their computer, TV and such a while before that. 
Even with a virtually direct hit, the surge protectors kept working. 
Not long after that, they wanted a UPS for their computer but also
wanted one for the TV, since the dish box takes a while to reload after
the power blinks.  So I helped them pick a fair sized UPS for the puter
and a smaller one for the TV.  The puter runs long enough to shutdown
normally and the TV is protected for those little blinks in power that
last just long enough to reset everything. 

One way to pick a decent surge device, look at the warranty.  If it
includes paying for items plugged in, then you're off to a good start at
least.  I just try to get as high a joule rating as I can.  The reason
for that, they can absorb more than one hit and still protect.  While
one large hit can disable protection, it can take out hundreds of
smaller hits and still work.  It all comes down to the quality of the
MOVs and the design of the protector. 

If you use Amazon: APC, Belkin and Tripp Lite are some brands I've heard
or seen are good.  I've used a couple of those brands myself.  I've
always heard that the Monster brand is also good but a bit pricey.  When
I researched them long ago, they are some heavy duty built products so
if a person has some serious power problems, they may be well worth the
expense.  I bought some on ebay that were Etekcity brand but it seems
they no longer make them.  I bought some that had a little over 5,000
joules of protection.  The only thing I didn't like, if power fails, it
stays off.  It doesn't have a hardware switch but a circuit switch that
resets on power loss.  That can be a good thing in some situations but I
don't like it. They are good protectors tho. 

Hope that info helps.  Also hope you can find something to prevent
future problems.
