Okay if the rest of you all are done with your immature flame war, I
can say through all my experience that is is definitely a bad
capacitor either in the vertical or power supply area. No cap should
be getting too hot, so this may be a symptom of the main voiltage
bias being out of range. Look inwside the back cover for test-points
and check that main B+ voltage is within 5% of spec (if given).

So the guy wants to learn, noone becomes an expert from a book alone.
If any of you people flaming were experts, you should already know
that. While I agree that diagnosis comes before adjustments, and that
some skill is required, he IS NOT FIXING YOUR EQUIPMENT, so get over
it. If they do something wrong, it's on them, not you, in case you
forgot....

Sheesh, seems people here are a bit too uppity about things that they
have made into their own personal problem. Quit shutting out someone
with an idea, everyone has to make mistakes to learn. You could all
suggest politely that the focus control will not fix it. For those
who want to know, I am self-taught on many a different area that you
will never understand, and know more in many than all the book-smarts
in the world.

8 years of college cannot teach what I have learned in as little as
five seconds...


There is a difference between helping someone to learn safely, and being
irresponsible. By saying that he had attempted to 'repair' his faulty
television set, by twiddling controls whose function he understood nothing
about, the OP demonstrated that he was not competent to be inside a
television set with safety. Now you may think that is ok, but I think that
if those of us who are properly qualified, and whose collective wisdom
exceeds yours by many times, were to recommend that he continued to poke
around inside an item of equipment that REALLY COULD KILL OR SERIOUSLY
INJURE him, this would be irresponsible, rather than helpful.

For sure, we all learn by making mistakes, but you're not gonna learn a lot,
if your first bad one puts you in the mortuary. In order to learn repair of
TV sets, and similar equipment, safely, you need at least a mentor, who is
fully qualified, and standing by your side watching your every move. You
absolutely MUST understand the safety angles of what you are doing,
otherwise, with a couple of repair successes under your belt, you will start
to become a self-proclaimed self-taught *expert* who then goes on to carry
out dangerous work on other people's equipment.

Whilst it is possible for qualified people to learn new techniques and hints
and tips from groups such as this, it is not possible for total amateurs to
learn arts such as TV repair, safely. Would you seriously suggest that
someone should try SCUBA diving, or sky diving, or mountain climbing or
racecar driving, without having been practically taught by someone who knows
how to do it safely ? No, of course not, and anyone who believes seriously
that electricity is not equally dangerous, is a fool.

No one has been *flamed* on here. Perhaps one or two of the comments were a
little less than polite, but if you think that is flaming, then you have
lived a sheltered internet life. Everyone from amateurs to professionals are
welcome on here, and will normally recive good and valid advice, but don't
expect those of us who take a responsible attitude to safety, to encourage
either those who don't, or those who have no knowledge of such matters.
