A couple of days ago I was watching my TV (1984 Sony Trinitron)
during a Texas thunderstorm.  There was a lightning strike *very*
close to my house and my TV went out.

The TV acts like it is getting no power at all.  The circuit breaker
in the house was not blown.  I assume lightning is a high voltage as
opposed to a current surge.  I should add that I am a computer
scientist with no real experience in electronics so I am in need of
*basic* advice.

I followed the part of the circuit that the power cord goes into and
saw the "main" fuse was intact.  There was one additional fuse (away
from the power supply part) and it was also intact.

I was looking for a "kind of power regulator" component just at the
point where the power goes into the "main board" but this seems to
be difficult to spot without a schematic or knowing exactly what to
look for.  Any suggestions for things likely to have been damaged by
such a storm?  How likely it is to be something I can learn to fix?
How extensive the damage is likely to be/How much to expect to pay
to get repaired?
