What is this guy talking about? CRT TVs are repaired by tracking down and
replacing faulty components, not the whole (unavailable) board.

This sounds like a capacitor in the vertical/frame circuit. Should be
an easy fix and a part costing cents - but given the size of the set,
I imagine that taking it somewhere is tricky. A call out will be
prohibitive, cost-wise. So I suggest you have a go - do you have a
soldering iron and som e solder? (available in a hardware/hobby store
I imagine). if you can post some pics of the main pcb , we can guide
you to the likely problem area. It would be a pity, and wasteful, to
dump an otherwise working set....

That was the most useful reply to the OP

Yea, if you say so...

Anything is fixable, IF you want to spend a lot of money. As far as
cost effective, I don't think so. Component level diagnostics and
replacement is not exactly quick and easy.

a lot of time. (= money)

Heh,I built a TEK 2213 o'scope from boards that other TEK techs replaced
because they couldn't find the problems on them.Got a free grade-B CRT from
the head of CRT Manufacturing,and only had to buy $20 worth of parts to
complete it.($20 after my TEK discount!)

'purpose built and unlabelled' components? what does that mean? In
fact, I suspect it means nothing as it is gibberish, although I
imagine most components are 'purpose built' for something - resistors
for providing resistance for one. Hate to tell you, but that's been
going on a lot longer than 2 decades!

As for unlabelled, I'd love to know what kind of 'unlabelled' gear
I've been missing these last two decades. Those of us who work on
these items daily can identify the components by reading those cute
little coloured stripes or printed text on them. If need be (for
example if a component is destroyed) we even sometimes look for the
component reference off the pcb, and consult the schematic. You know,
you can even find lots and lots of them for free on sites like
eserviceinfo.com. Try it one day.
