Default Soldering a Broken TV

I started having trouble with my TV after it was moved in a U-Haul from
San Francisco to Seattle. I managed to locate a faulty solder joint on
the board. Applying pressure to the joint with a strip of wood fixes
the problem.

My problem is this: I am very experienced with electronics and
soldering, but I have little experience when it comes to high voltage.
I need to fix the solder joint but I have no hardware to properly
discharge any high voltage capacitors in the TV. I don't think this is
a problem as the faulty solder joint is attached to what appears to be
a FET. However, it could also be a triac, which could mean that it's
attached to a HV part of the circuit. I don't want to stick my head in
there to find out exactly what it is. Would you advise fixing the
solder joint without first discharging the TV?

Thanks in advance!

Huh?

You're "very experienced in electronics and soldering" yet you don't
know whether something is an FET or a triac?

I don't want to stick my head in between the high-voltage electronics
and the CRT to see it more closely.
