Toshiba TV success!

I posted about my 32 inch Toshiba TV with the squatty bodied, cone headed
picture with the three inch black band across the bottom. Thanks to the
excellent advice that I received here, I sent away for a dozen or so, high
temp caps for the vertical section and the surrounding area of the board.
I'm a rookie and was mostly worried about getting zapped. That didn't happen
and I was able to unsolder the caps using Rat Shack wick. It worked pretty
good but was rather tedious. In fact I only used about half the caps that I
ordered. I started to resolder the IC, but thought better of it when the
solder started to run down each connection and wanted to ooze together. I
guess one is supposed to totally remove all of the old solder and then redo
it. I also almost messed up a trace by trying to bend the leg of a cap
straight before cutting it off. In retrospect, I see how stupid that was. It
didn't break but did lift off of the board slightly. The trace was at the
edge of a part of the circuit and I could have duplicated the path to the
next component by soldering a small wire between them. I was wondering if I
should have tacked it down with a drop of Super Glue or maybe a small dab of
hot melt. Anywhooooo .... plugged it all back up and hit the switch and,
bada bing ... works like a charm! I put the cover back on and gave it a good
bouncing and shaking to make sure nothing was ready to come loose. I then
left it on for over 24 hours ... still fine. The worst part of the whole
thing is a sore back from lugging it our to the garage and back.
While doing some reading on caps, one maker's page said, "do not
straighten caps, that are soldered into place." Am I the only person here
that can't seem to resist? It's like not squeezing a black head.
The only other minor problem that I ran into was, a small cap without any
kind of polarity marking and nothing on the board. I reinstalled that one.
How common are those?
Well, needless to say, I'm glad that I didn't just toss the TV in the trash.
I wasn't about to lug that monster down to some shop, owner unknown, and pay
to have it fixed. It's a 1994 model ... not something that one wants to sink
a lot of money into. Hard to believe that just a few dollars in caps made it
right as rain. Thanks again, for all of the help.
