I found the repairfaq.org tv page. It looks quite useful, but we will see if
I can fix this thing..

I know what not to touch inside a tv. I've read up on crt safety in the
past because I have had a few projects where I had to remove a tv from its
case and mount the crt in a fixture. I know how to ground the crt tube and
caps. My biggest problem is finding the bad component. Would you suggest
replacing all of the caps in the power supply section of the chasis? You
said a short in the power supply sounds like a possible problem, could I
check the caps with a ohm meter and just replace whichever one is bad?

One thing I just remembered. This tv gave me trouble (doing the same
thing) in the past and if it were upside down it would work. So I assumed
that there was a cold solder joint somewhere. I thought I had fixed it
because the solder was cracked on a large capicator and I reflowed it. It
worked fine for a few weeks. Then it started working some times and not
others. A good whack used to fix it. I havn't used the tv in a while but
the problem started again and now it just won't power on at all no matter
how much you hit it.

I think I will check for shorted out capicators with the good ole ohm
meter and look to see if that cap came loose again. I'm not sure that was
the problem to begin with, but the solder was cracked on it.

Hi!

Something in your TV is shorted or the regulation in the power supply has
become faulty.

What you are seeing (and hearing) is the power supply attempting to come
up
and then shut down again. Normally this happens when the outputs of the
supply are shorted or even overloaded. Since you mentioned seeing channel
numbers flicker on and off on the set, it is very possible that the power
supply itself is where the fault lies and that the rest of the set is
fine.
As a wild guess, I would say that bad capacitors in the power supply are
likely.

If you don't know where to start and you want to have the TV fixed, then
it
might be advisable to take it to a shop and get an estimate on repair.
Provided the TV was working well prior to its failure the cost of repair
may
be worth it. If you want to learn to repair electronics, I wouldn't start
with a TV set. There is just too much inside that can give you a nasty
surprise or even ruin the whole day (and a lot more) if you don't know
what's all going on in there.
