Default TV with short circuit - how do I find the short?

Thanks for the advice, but I think I have made an informed decision to
cease
work on this TV as too many people have told me on the group and in real
life that I am more than likely to end up touching something that could
kill
me. The set does not have a mechanical on off switch, but the fuse blows
as
soon as the TV is plugged in, before the standby switch is pressed. As I

said, I am most likely discontinuing work on this TV. I found a similar
one
in working condition for 25 dollars on craigslist. Thanks again.


In all the responses to this posting, the one thing I believe no one has
mentioned is the need to obtain a schematic and servicing information for
the TV. Without the schematic, you are flying blind. Some of us could
make a start at trouble shooting a shorted power supply by a visual check
of the components on the various circuit boards and making resistance
checks on the obvious power rails. Sometimes wisdom comes from experience
and the wisdom helps to identify dangers. But there is usually no
substitute for a schematic if the damage is not visible.

Good luck and stay safe.
