is there a `getting started` how to sort of thing anywhere i

Rebuilding a carburetor on a television is not much different than
rebuilding one for a car. Just dive right in. Take out components,
clean them with solvent, replace the worn ones, and put the rest
back as you found them originally. It's best to work with the TV
plugged in so you get some light from the CRT, and it makes it
easy to find ground.

didn't say it didn't take knowledge, it's not knowledge it's experience that
really matters, in my opinion. But, regardless that knowledge dooesn't give
them the right to charge you 400$+ to fix a .60 cent problem.... that's like
me charging them 700$ to do a headgasket on a car, it'll take me 2 hours,
and a 30$ part....i guess it just depends on what your morals are, i charge
150$ to do a headgasket, i guess i just need to find a tv repair place thats
like me, the world sadly tends to revolve around greed so it seems, could be
tough.

Gotta love the "throw-away" electronics we have nowadays huh ?

Why would a consumer pay $75 to replace a transistor in an old CRT when
they could go and buy a brand new CRT (with a Warranty) for just over $100.

Tis the price of progress I suppose.

Go For It.......I have been a tech for 43 years---TV, Projection TV, LPTV,
High Definition TV, VCRs (BETA and VHS and "C" and 8mm), camcorders (8mm,
"C", VHS, Digital), and this is not an easy thing to learn. 2 years
schooling, over 100 mfg "Donkey Shows", self learning from books, on the
road and on the bench. Do I charge $200-$400 to replace 2 30 cent
capacitors, you bet I do, but I am a TECHNICIAN---not a "cherry picker", a
"shotgun repair idiot" or a moron. I retired last year...in my retirement
I
work for shops, do work shops won't do, clean up messes form unqualified
consumers and "technicians. I also make about $ 80,000 a year and pick and
choose who I want to do work for. GO FOR IT ! It is a lot of work, study
and
frustration, but if you can live through it and be come good at it after
20-30 years then you will truly be independent, emotionally and
financially.
Shop owner have by true admiration having to put up with "know it all
consumers" that are dumber than a brick and in most cases don't have a pot
to piss in.

On the A+ test I took years ago, the answer to the question "What
should you use to discharge a CRT you are going to be working on?"

The answer was a 10,000 Volt test meter probe.
(no, I am not just going by this knowledge as my reason for writing
this)

The innards of a CRT/TV/MONITOR (whatever you like to call it)
has LETHAL amounts of electricity in it, even after powered off and
unplugged.

The other persons reply that it is easy to find ground is correct.
Because when you dscover ground, you will probably be the GROUND and
will zapped across the room if not killed outright.

Am I being cautious. You bet your ass I am. But it pays to be, in
this case.

Just be careful workin' in there.

And don't wear jewelry, rings, etc. They're condictive.

Cheers.

is there a `getting started` how-to, faq, etc... out there for TV repair? I
have a multimeter, and soldiering gun (nice one), but i need to know how to
test/check the various components and diagnose the problem, anything would
be helpfull, as i just paid 360$ to repair my last tv, and i know it costed
them about .60 cents and 10minutes of thier time, sick of getting ripped
off!

10kv is a bit low, most TV's are 25-27kv. Low current though, hurts like
hell, but probably won't kill you. No point in being careless though, you
can easily rip your hand open on something when you jump back.

Interesting comment that. Considering the guy who fixed it probably
spent two years full time studying electronic engineering, and has
several years experience, and tens of thousands of dollars worth of
tools and test equipment... etc.

It only took 10 minutes because they knew exactly what they were
doing. You pay for that experience.

oh, and surely it would have cost more than 0.6 cents. Even a cheap
resistor costs more than that!

People like that are exactly the reason I chose not to repair things
professionally, people who don't repair things don't understand how much
knowledge and experience is needed. I figure if they don't wanna pay someone
with the experience they should quit whining and start learning, all the
information they need is already out there online, the rest is just
practice. You only need a few hundred $ worth of tools to do most repairs,
and most of that is a decent multimeter. The parts that most commonly fail
are fairly easy to test, it's just a matter of knowing what parts to test
based on the symptoms of the device.
