Looking for CRT monitor repairer in Sydney

[Peter Urbanec]

I'm looking for a competent monitor repairer in Sydney. Ideally lower
North Shore.

I've got a high end Iiyama CRT monitor where the horizontal deflection
has failed. I would like to have it serviced by someone who will ensure
that the geometry and convergence are spot on when they are done
repairing the unit.

How big is it? The guys I used to use have given up & I haven't bothered
getting a CRT repaired since (about 2 years). Sub $400 for a 19 inch LCD
means that my customers can't justify the repair cost.

Competent consumer electronics techs are extinct!

A retiree, a hobbyist, an adventurous DIYer, or someone just managing
to hang in (and who's so bad tempered he'll eat you for breakfast) are
your only hope. )

You won't get any argument from me, it's my customers (or more
accurately their accounts departments) who make the call.

There's plenty of decently priced CRTs cheaper than LCDs.

An LCD fed by a digital connection is adequate for editing text, but
not for accurate video. The faulty monitor has the correct ITU
phosphors for accurate colour reproduction and is/was good in terms
of uniform gamma curve and black point / white point dynamics.

I'm prepared to pay up to the same amount of money as a new consumer
level monitor would cost to have this one repaired. Finding a decent
quality monitor these days is difficult - they all reproduce colours
in Fisher-Price mode, i.e. better than the real thing :-(

I suspect that the problem is a fairly simple failure in the
horizontal deflection circuitry or power supply. However, I've seen
monitors come back from repairers looking worse than they did before
they went in. I'd like a recommendation for a shop that can be
trusted to do it right. I'm prepared to pay for the extra 30 minutes
of labour to ensure that the result is still a high end monitor, as
opposed to a working CRT tube.

I'm quite happy to take recommendations for good TV repairers - I can
always ask them on the phone if they are willing to take a look at a
computer monitor.

In other words, I'm looking for good old fashioned service done by
someone who takes pride in their job. That probably implies an old
school analogue electronics engineer.

Not if its a basic electronics failure like the power supply etc.

the job they did for me one done quickly and flawlessly, happy customer
here, but perhaps an easy job?

just my 2c.

Thanks for the tip.

Sibnet are in Chatswood and have been for at least the last 10 years.
All the way up Victoria Avenue and over the hill. I used to take my
Commodore gear there for repairs and it was a long walk from the
station. Not sure about their service levels these days, but back in the
early 90's they rated average to sloppy.

I'm afraid I can't give accurate diagnosis, I just don't know enough
about the inner workings. It could be one of the power supply rails, but
it's certainly not the main transformer or primary winding, because the
picture is compressed to a vertical line and the intensity of various
sections of that line changes as the computer boots and displays
different images. Then again, as the different resolutions switch during
the boot process, the monitor does not go through the normal relay
driven resolution switch noises.

For a couple of months before the monitor failed, I used to get monitor
OSD firmware crashes, that resulted in the monitor menu system locking
up or showing corrupted data when the monitor came back from standby. A
simple front switch power cycle would clear these up - although they
would only happen once every couple of weeks at most. Hence my suspicion
of some power related issue, but it could equally well be some sort of
other issue that just resulted in a voltage feedback into the digital
circuitry. I'm just not qualified to point a finger in any direction,
hence my desire to take the unit to someone who knows how to identify
and fix the problem without boloxing up the display quality. Just
getting the picture on the screen is not good enough, it has to result
in good quality picture when they are done with the repairs.

As far as I am concerned, RF electronics and to an extent most
transistor level non-digital circuits, are black magic to me. My hat off
to anyone who can get their head around circuits that operate above 100MHz.

Yeah, thats now clear.

Unlikely with those symptoms.

but it's certainly not the main transformer or primary winding,

There isnt any of those in the power supplys, they're all switch mode.

OK, the HOT has failed, what drives the beam horizontally.

May well be a completely unrelated fault.

Yeah, and your comments about monitorhospital
dont engender much confidence at all.

The stuff like that lack of horizontal deflection is pretty basic.

LCD's can be had now that are as good if not better than CRT's for

Seimens and NEC, and others,

They are companies, not monitor models though.

OK, I have no experience with their requirements.
Quite different from quality photographic printing purposes probably.

I'd expect so. The photographic stuff is going to be *way* less

detailed, coloured and 'realistic'. People get funny about doctors
needing to see the cancers clearly.

And no, I couldn't name the models, but they certainly wouldn't be
available for home or general business use. But the technology is there,
so eventually it'll trickle down.

Cheers.

You have this back to front. Doctors/scientists use *enhanced* or false
colors, or increased contrast to better identify similar areas under
investigation.
More "realistic" is *not* part of their requirement. I suppose using dies
on
microscope slides is to increase realism in your opinion!
Maybe you consider an X-ray photo to be more "realistic" than a normal
photo
too?

And no, I couldn't name the models, but they certainly wouldn't be

Ah, that's the point. Even the crap LCD's are more expensive than a CRT at
present.
I too look forward to the day when a cheap flat panel display outperforms
a
CRT, and yes it will probably happen sometime. (note I did not say LCD
though)
In the meantime I am quite happy to use both, as required.

MrT.


Not denying that the imaging they use is false imaging - however they still

need resolution and definition (yes, realistic, even in quotes, was a bad
word to use). I was in Chicago for the conference before last (the missus
being a radiologist) and meandered around the stands. The displays were
absolutely awesome. I've done a lot of imaging in my time but never thought
I'd see that sort of stuff!

Cheers.

I'm rather fond of my Samsung DFX series monitors. I bought 3 of them
when the bottom fell out of their price a year or so back. As flat as
you can get and still be a cRT, good colour etc.

I'd like an LCD, to save desk space, even better I'd like a dual input
panel that can either run as a single monitor or be split between two
desktops or 1 desktop and AV. Anyone know of such a device?

Agreed. Resolution and definition are not the main problem for LCD.

Yep, when money is no object, there are some wonderful displays available.
I've done a lot of imaging too, and I sure hope the prices become realistic
sooner rather than later.
(not everyone has a radiologists income unfortunately :-(

TO buy a decent CRT display is in the same league as a decent LCD

How about $7500 for an Eizo ColorEdge CG220 22.2" LCD Display?
http://www.cyrachrome.com.au/view_products.asp?CATEGORY=7

Now find a decent CRT monitor for that price, that is providing you
can find one at all. Dont forget, if you want to compare the eizo, we
are talking about monitors than can replace the need for hardcopy
proofs.

BTW my 22" Mitsubishi Diamondtron crt monitor still has excellent focus,
contrast and brightness when coupled to a Matrox graphics card.
It cost a lot less than a current top quality lcd, but of course takes up a
lot of space and has probably been discontinued.

I bet your mitsu monitor will be outperformed by the eizo. I beleive
eizo have discontinued there CRT models now, so this must be saying
something for LCD.

In the meantime I am quite happy to use both, as required.

I'm sorry Paul but Philthy's technical ability finishes with
toasters. Remember how he buggered up a set of Quad ESL 63s
by playing with things he didn't understand?
