James,
I always replace that 100uf 200 volt cap just for general principle.
They fail regularly.
The transistors aren't that critical on specs so you should be ok.
Not like a Sony.
If you do need some assistance for coolant issues just holler.

Good Luck,
Bill Jr

I replaced the HOT with something I had in my scrap box that has similar
specs, NTE lists the same replacement for both it and the BU508V so
hopefully it'll work. Replaced the BUW12A with another similar transistor,
should have ordered more than one of the correct part, but at least if
that
fries again it should only take out the fuse. The TV is out at my mom's
place and the boards are here so I'll have to drive out there and see if
it
works. The ESR checked out ok on that cap, does it usually fail? I did
find
quite a few cracked solder joints, figured that's probably what caused the
original failure.

As for the coolant, I'll cross that bridge when I come to it, so far I've
been lucky and never had to deal with contaminated coolant, first time for
everything though I suppose.

James,
Usually the H.O.T. short will take out that BUW12A.
Mostly caused by poor solder connections everywhere.
The H.O.T. can be replaced with a 2SD1710.
Unless you have the original BU508v laying around.
You will most likely have a coolant contamination situation when you get
it
running.
Also, always replace the 100uf 200volt cap in the power supply.

Good Luck,
Bill Jr

Got this set dead, fuse was blown. Replaced the BUW12 on the power
board,
checked out the rest of that board and fired it up. Power light came
on
then
set went dead, stupid me, I missed the separate HOT on the sweep
board,
it's
shorted too. I plan on replacing these parts and trying it again, but
first
is there anything major that often fails on these sets? I'm hoping the
flyback and HV block are good, it's a fairly old TV but looks to be in
nice
shape and has been sitting for several years.
