My brother has a nice 27" tube TV (flat screen) that
has gone bad. The unit is only abt 6 years old.

They were watching it Sat night and the picture shrank
down to one thin horizontal line that stretches across
the screen. In other words. it has no vertical scanning
I think.

He said I could have this TV if I wanted it but I live
in a rural area and no where to take it to have it
fixed!

So.... questions:

1. What is the part that has failed in this set given
its symptoms?

2. Is it worth fixing it? If yes, where can I get the
part and could I install it myself?

Thanks!!

TVs are like Bic lighters. You can fix them but it is seldom worth
trying.

I'll second that....There could be any number of "parts" which have
failed, or perhaps just became disconnected because of a cracked solder
joint.

It ain't like the olde vacuum tube sets of the 50s I used to repair back
then. yYu could at least see all the components without a magnifier, and
they had easily read identifying part numbers/values marked on them.

Give it up...

Yes, the cracked solder joint is about the only thing worth looking at
or fixing. A common issue with Sony stuff, where stress cracks form in
the solder around component pins due to thermal cycling. Easy to
identify with a magnifying glass and if found the fix is to just
resolder every connection and the item normally works fine for another
decade.

It's probably a simple repair, especially for someone that has fixed that
same tv a dozen times. The tech would look at the symptom and say, oh it's
that 100uf 250v capacitor again or the vertical drive transistor. That will
be $110.00 for the repair. The repair is usually simple, knowing the part to
replace is the hard part. Get the model number and put your question on some
of the electronic repair groups. Maybe you'll get lucky.
Mike

Post your question with the exact model number to "sci.electronic.repair"
[I've changed a single capacitor with the advice given there and restored TV
sets. The key being knowing exactly the probably component.]
Since you aren't electronically inclined, you possibly won't want to pursue
this unless it is a well-known or easily diagnosed fault.

Considering that analog over-the-air TV will shut down on 2/17/09, I would
chuck it and buy a new one. 6 years old isn't new because it's an analog TV
and it will be a boat anchor on 2/18/09.

That is onlty true if you get your TV over the air. I think most
people have satellite or cable these days.

I use over-the-air TV. So does my mother. I got the converter box so
that my analog TV (4 years old) won't turn into a pumpkin on 2/18/09.

Cable is not worth it to me. I think satellite is a better value but
still not worth it to me - I hardly watch TV except for news, a couple
game shows and Dancing With the Stars.

My apartment complex prohibits satellite dishes. I wonder if that is
legal.

Tell your brother to treat himself to a nice HDTV. At least now he has
a reason since his TV died.

I had a fairly new set die, I took it to the repair guy too look at. I told
him if he could fix it for $75 or less, fix it. He did, now I have a nice
extra set. I also told him to junk it if it was more than $75 to fix.
In my case it worked out good to fix it.

Having just gone through the same
process with a 3 year old
36" RCA, I thought I would chime in
here. My TV just shut
off one day, by itself. A friend told
me about a place that did
free estimates and he thought they were
pretty good. So, we
loaded up the boat anchor in the car,
did the 10 mile trip and
dropped it off. Later that day I got a
call from the repair guy ....
$129. I said of course, do it. If you
can find a good repair
guy with free estimates, it's worth a
try. I didn't want to replace
the TV yet because of an impending move
and I figure the flat
screens will still come down a bit more.
It also fit real nice in
the present entertainment cabinet. BTW,
I got the TV
back in 3 days and am very happy with
it. After the move,
in maybe 8 months or so, it will
probably be replaced or moved
down to a bedroom TV or such. But
for now I don't have to fool with it.
If you live in the Chicago
suburban area (Countryside, IL), the
guys at Fox Electronics
are real good and fair.

No it won't. There are (and will continue to be for a long time) many
sources of NTSC (analog video), such as cable and satellite receivers,
DVD players, etc...

That is onlty true if you get your TV over the air. I think most

And DVD players, VCRs, etc...

BTW, I do know someone who has no broadcast TV source, and uses the TV
only to play tapes and DVDs.

They would replace the 50 cent part and then sell it in their "show

Back up a little. Google for "sci.electronics.repair faq" and read everything
you can.
Also search for some other clever search strings like "tv repair symptoms"

What you have is a problem with the vertical deflection. You already knew
that. It can be a problem anywhere starting to where the signal is
generated (on some chip), amplified, and wired to the yoke around the neck
of the CRT. Usually the problem is the driver transister (vertical output).
Or a bad solder joint. Or wiring. Or the yoke. In my experience, at least
half of all faulty electronics are due to something physical: a bad solder
joint, short in a multilayer circuit board, connector, cable, switch, etc.


2. Is it worth fixing it?
Probably not. If your time is worth minimum wage then it isn't worth fixing
yourself either unless you already have the requried electronics skills and
can handle troubleshooting complex electronics. If it is going to take you
two hundred hours to diagnose and repair, then you might consider your time
better spent elsewhere.

A TV repairman, if you can actually find one, probably won't bother looking
at it. Nowadays, anything under $400 to replace simply isn't worth being
repaired. Consider that you're going to have to buy a digital tv adapter in
february. Add that to the cost of the repair ($150-250) and you're well on
your way to replacing it.

If yes, where can I get the part and could I install it myself?
What part? You have to diagnose it down to the component, connection, or
circuit board first. You'll probably need an osciloscope to trace the signal.

Most tv repairman nowadays only diagnose down to the board level. They have
a stock of replacement boards so they can try swapping them out fairly risk
free. If you try that, you'll be lucky if you fix it for less than twice
the cost of a new TV.

Unless you live in your TV, this really isn't a home repair question. Try
sci.electronics.repair. But, please, read the the FAQ and get a clue first.
They're not going to teach you how to solder or procure basic
troubleshooting skills that are already detailed in the FAQ. They will,
however, be able to tell you if the particular tv model has a history of
problems.

This should be a cheap fix if you do it yourself. Look at the
vertical sweep circuitry. The problem could be a bad solder joint or
electrolytic capacitor around the vertical oscillator chip, a high
voltage electrolytic capacitor (probably at least 180 volts) in series
with the vertical yoke (those coils of wires around the rear area of
the CRT) , or the vertical output transistors. There are two of those
transistors, and when one goes bad, so does the other one. In a lot
of TVs the transistors are built into a chip, and that chip may also
contain the rest of the vertical circuitry.

You may be able to find a schematic on the web, especially from
Russian websites (a friend of mine bought a schematic from one for $5,
maybe from http://top.eserviceinfo.com or Radio Locman), or your
library may have Sams (not Sam's) Photofacts, either on paper or
online. It's even possible that Sears.com has the repair manual
online (they do for major appliances).

If you don't know how to solder and desolder, practice on a junk
circuit board. The TV is probably made with one-sided circuit boards,
which are by far the easiest to solder and desolder. Desoldering can
be done with a suction bulb from Radio Shack, but copper desoldering
braid is probably safer because it lessens the chance of overheating
the copper traces and making them come unglued. A 30W iron is good
for soldering single-sided boards, but 40W is better, especially for
desoldering.

If you work on the TV, unplug it first! And don't set it upright on a
soft surface, like a sofa or mattress, because it can easily tip
foward (center of gravity is just 2" behind the front of the screen).
So either place a pillow to catch it, or work on it face-down. Be
careful not to bump or scratch the glass CRT.

Parts prices can vary a lot. Some good sources are MCM Electronics,
MAT Electronics, Dalbani, Premium Parts, and Tritronics, but don't
overlook Sears or even the manufacturer. Generic parts, like
capacitors, can be bought from any electronics supply, but be sure
they're rated for roughly the same capacitance (it may have to be
fairly close for vertical timing capacitors -- I once replaced a 1uF
with a 10uF, and the picture was only 2" tall) and at least as much
voltage as the original. BTW capacitors can't be tested reliably with
just a meter, even a capacitance meter, and bad caps can look
perfectly good. If you're replacing electrolytic caps around the
vertical chip, consider replacing all of them. And don't install any
of them backward!

Even though analog TV is scheduled to go away in Feb. 2009, converter
boxes are only $10-20 if you get a free $40 discount card (limit is
two per person) from DTV2009.gov. I'm using one with a vintage 1976
TV that used to belong to my parents and still works fine (was made in
Japan).

Times have changed. I guess a CRT TV is now considered a tube TV.

Anything is repairable if economy is not considered. LCD TV uses less
energy for one reason. What is symptom any way? No picture or sound or
both?
