Either one would work, but you will probably find that 67104 isn't
available unless someone has one that's been gathering dust on the
shelf for quite awhile.

I managed to find a 67104 for about $74. It came to $90 with shipping
and tax. I'll see when it shows up--God bless the Internet . . .

I see the transistor is used for horizontal deflection. So would that
explain the lack of display right there? What about vertical?


No, actually Q802/T801 does horizontal deflection, tube filaments,
28 Volt supply for vertical and a couple others. Q906/T900 does
only the High Voltage for the CRT's, which is (usually) why you get
no picture but everything else works.

That's odd; I thought the datasheet stated it was horizontal deflection.
As long as it works . . .


Usually T900, Q906, R934 are all that is needed, unless there is
something else wrong with the set. I'd give the solder joints a good
visual inspection while the board is out and re-do any that look bad.
Barring elctrical problems, it's likely to need fluid change/optical
cleaning, minor convergence and color balance tweaking.

I've read some stuff in the FAQ and convergence and color balance. I
guess I have to get myself a test pattern. It has an S-Video in so I
figured my laptop could provide that signal. This is the first I've
heard that there's fluid to change in a television. I see on google
what it's roughly about. Does it come down to scooping stuff out with a
turkey baster?

As for optical cleaning, I assume rubbing it with Q-tips of some
solution would be ideal; perhaps using one of those towelletes that come
with glasses. I'm not going to guess what exactly, but it seems like
there's good information online about it.

I'll update with a new thread when I get the parts and my tools ready.
It'll be fun taking off that board so I can mess with the parts easily.
