Default CRT Monitor crackling (also when powered off)

Hi all,

As the subject says, my trusty Samsung 17" CRT has developed an
intermittent crackling noise, which would seem to come from the back area.

It's also present when the monitor is powered off, so I would think it has
something to do with the power supply circuitry.

Now i'm no electronics technician, but I do have a multimeter and a
soldering iron.. Does this sound something I can fix with a moderate amount
of effort (and without zapping myself)?

Bob:
While "meatplow's" reply to your posting was rather blunt and direct, his
assessment is absolutely correct... this is not something you are going to
be able to repair yourself given the information in your original posting.
If you want, you can do some more research by going to the website for this
newsgroup at
http://www.repairfaq.org/
there, with some search time you will find a lot of relevant repair and
SAFETY information that will most certainly confirm the probability that
this is not a home DIY repair.
It may be time to take it to a shop for at the very least a repair cost
estimate or replace the monitor.

And should add that now it may not need more than having some solder
joints touched up joints. But if you let it go on like this, more
serious problems may occur.

If you have to ask that then no. But learning how to be safe in there
isnt hard, and the fault is fairly likely to be no more than a broken
solder connection on the power supply, which would be very repairable.

What do you hope to accomplish with the soldering iron, multimeter and
technical knowledge?

Fixing your monitor? no.

Sticking the iron and meter up Sitre Magana's ass? Yes.

Bob ,
Did you ever open it up and clean it? Its probably high voltage
arcing over . You can try to clean it, but first you should read
the manual. You have to, of course pull the plug, wait a few minutes,
then open it up. Also, you might have to discharge the high voltage.
Being careful, do not move or bent anything, use a small vacuum, to
suck out all the dirt.
P.S. The high voltage can still be there with the power off, and the plug
pulled! Careful!

My 2 cents worth!
