Monitor Repairs

Folks:



I have a laptop and a regular desktop computer. The monitor for the desktop
recently stopped working. When I turn it on, there is a white glow with no
visible text or images.


(1) * Is it possible for me to somehow use my LapTop (maybe with
some special type of cable ) to view the boot
process of my desktop computer ?


(2) * Has anyone here ever repaired a computer monitor ?

When monitors stop functioning (flickering screen, no response, etc) what
really is the problem and is it possible to do repairs to solve the problem
?



PS The simplest solution is to buy another/new monitor. However on this
occasion I wish to attempt repairs FIRST.
I have no experience here so I am trying to tap into this
newsgroup's expertise.



Thanks,
John.
 
I recently had a CRT monitor go bad and could not find anyone to repair it,
not even Dell.
You said it has a white glow, did you check the connector at both ends?
Also check that the video card is fully inserted.

The high voltage supply in the monitor is likely in the neighborhood of
17,000 volts. Please do not remove the case. It is a job for a qualified
technician.

You want to repair it yourself? Monitors harbor extremely high voltages,
even turned off. Unless you are expert in this, trying to fix a monitor
yourself is playing with fire. You can very easily kill yourself like this.

Trying to have a monitor repaired by an expert is hardly ever worth the
price. Monitors are cheap enough that paying someone to even look at it is
not economical.

Just got a fax a week ago from a local distributor. Buy a dozen 17" ers,
pay $25 each. No guarantee, no delivery, no warrantee.

Chances are the monitor has died. Confirm that by connecting a known
good monitor. A good reason to keep those 15" tubes around when you buy
flat panels so you can use for testing.

Yes. They are NOT worth repairing anymore.

Of course Dell wouldn't be capable of fixing a crt. They don't build those
things, you know. One could always take a crt to a regular TV repair person
and they could probably diagnose the problem and fix it. Whether it is
worth the expense considering that today's electronic devices are
essentially throw away devices and sell dirt cheap is another matter. A TV
technician will have a flat fee for just looking at the crt, but the
replacement part might only cost a few cents and might be worth fixing,
although I have my doubts considering how cheap crts are these days.

Very wise words from Ken.

Take it from an electronic hobbyist, never try to fix a CRT TV
or Monitor, you will get zapped and die eventually, no, no,
never do it !

We even lose a few experienced TV technicians and
electricians each year, by death from UNPLUGGED CRT
TV's and CRT Monitors.

Where do I sent the flowers to the next-of-kin.

Go buy a new Monitor you cheap skate. -:) LOL

And if you put the old one out on the curb for council cleanup
day cut off the power cord, and with thick texta colour write
across the screen "DANGEROUS FAULTY DONT USE".

The most likely "Experience" will be something around 30,000 volts, even
with the monitor turned off because that CRT is a big capacitor.

What you described, (no images of any sort it sounds like) is quite likely a
component failure and by the time you've hunted down bits and learned to
solder it is going to cost you more than a new monitor. It might be
different if you were an electronic hobbyist and had a stock of components
already to hand, but from experience the bit that fails is never any of the
ones you have spare - that's just life.

Almost nothing is "Adjustable" in monitors these days, there's no "Presets"
to adjust because it's all done electronically, so unless it's just a bit
out of focus there's really nothing much to gain.

It was a Dell monitor and they do sell refurb monitors which means they must
have some kind of return and repair system even if it's a contract with an
outside shop.

Presently it ususally costs $80+ to repair a monitor. One can buy a new
and better monitor for $99. LCD a little more.

Although I agree that it seldom makes sense to repair a monitor, it
certainly isn't always true that a monitor you can for $99 is always going
to be better. It depends entirely on which and how big the older monitor is.

To cite an extreme counterexample, I have a friend who is nearly blind, and
uses a very large very expensive monitor (I think it's 30", but I can't
remember for sure). It would cost multiple thousands of dollars to replace.
His is a good example of a situation in which repairing it would normally be
justified.

Even for 19" monitors, good ones aren't available for as little as $99.

<snip>

The most likely fault is a failed Line Output Transformer, often caused
by a failure of a high voltage capacitor. In that case there would be
no high voltage and no image at all.

You will often find that a back-street firm which repairs CRT
televisions would also be able to repair it. LOPT replacement cost
would be about £100 + .

If one _has_ to play with high voltage equipment, old engineers do it
wearing rubber boots and with one hand in their pocket.

To paraphrase a tag about pilots, there are old HV engineers and bold
HV engineers, but there are NO old, bold HV engineers.

You are talking extremes. I paid US$621 for a 17 in CRT years ago.
CRT are a rarity now, but I seen a flat screen 19" at walmart for $129.

Just got an ad faxed to me for 17" CRTs for $29 each. Shipping extra.
Tho, I can drive 30 miles to the port and pick them up. I figure I can
get them for $19 each with cash at the dock warehouse.
