The common cause in your CRT monitor is that many of the electrolytic 
capacitors become temperature sensitive with age and use. The cost of 
servicing your monitor would most likely exceed the replacement value. This 
is not a repair you can easily do yourself, unless you are experienced in 
servicing monitors.

Much of what you are going on about the life span of LCD monitors is a lot 
of hype!  Get yourself a good LCD monitor, and you will be very happy with 
it. I would never go back to the CRT type again. In a way I have no choice, 
because in about a year, there will be no more available, unless bought 
used.

The Viewsonic, and Sony in their higher end models are excellent. I have a 
number of Viewsonics, and I am very pleased with them.

After only 4 years, my Samsung 950p gave up (I bought it as an end of line
model.) For no apparent reason, sometimes the sides wobble, and then, from
the center towards top and bottom, the screen gets fuzzy. If I change
screen resolution, it's OK. Then, it gets fuzzy and I must change
resolution again. Etc. Samsung suggested that they maybe could fix the
problem for close to the price of a new 19" CRT monitor. Without the
guarantee, of course.

Sometimes the screen is absolutely perfect for an hour or two, so I doubt
it's a big problem but, for a lack of service at a decent price on CRT
monitors, it seems I'll have to scrap it, unless you can give me an idea
of the problem. If it's apparently not a major problem, maybe I could get
somebody to take a look. If not, I'll have to go for a LCD, though I'm
less than enchanted by the technology.

I'm considering 2 LCD monitors. The one that best fits my needs -- 
writing, browsing the net, looking at pictures, DVDs (well, maybe one day)
-- would be a LG L1952T, also sometimes refered to as L1952TX, apparently.
300 cd/m2, contrast 1400:1, DVI-I (standard DVI, I suppose?), 8ms. Picture
quality seems OK. Price: $289 CAN.

The Viewsonic VX922, is less bright (270 cd/m2), the contrast is not quite
as good (700:1, if I remember well), but it's a 2ms, a monitor for gamers.
  Accordingly, it's $50 more expensive: $339 CAN.

Salesman ALL tell me that I'd be much better off with the Viewsonic. They
tell me that the Viewsonic quality is much better. The VX922 looks like a
hot seller for Viewsonic, so maybe the price is set a bit lower than for
other models.

A friend, who knows more about electronics than I, told me that, besides
pixels dying, the main problem with LCDs is screen fade out. So, unless
Viewsonic's pretention that their light source has a 40,000 hrs long life
(other models have a 50,000 hour life expectancy, though) I suppose I'd
theoretically be better off with the LG.

But I'm not a gamer and never will be. My feeling with LG support is not
very good: they don't even have an 800 number for support!

What is your experience with both Viewsonic and LG? Which monitor would
you go for?

   So, how long will the 100+ spare CRT monitors I have on hand last for
me? ;-)

Hype? Most people tell me that after the warranty period ot's just about 
finished.

> Get yourself a good LCD monitor, and you will be very happy with

I wonder. First, from what I read yesterday on LG's site, it seems that 
you never get 16.7 million colors unless you pay a hefty price and are 
ready to cope with a slow response time. Instead, what you get is (2^6)^3 
or 262,144 colors and dithering makes it look like 16.2 M colors through 
dithering. So a 6 bit panel sould be recognized because specs say 16.2 
instead of 16.7 M colors.

Viewsonic never says if their LCD panels are 6 or 8 bit, bever speak about 
the number of colors. The VX922 is certainly a 6 bit because it's fast. 
What they do say is that unless you get seven burned pixels on a 17 or 19" 
monitor, they won't replace it. LG doesn't specify the number, but they do 
say that the replacement they'll send you could have dead pixels too, that 
producing perfect panels would be too expensive.

So what's the advantage of LCDs? Would you like to cope with 6 dead pixels 
on your screen for years? They take less place on your desktop and take 
about 2 or 3 dollars worth of electricity less a year. Big deal!

> I would never go back to the CRT type again. 

Why? Mine has a refresh rate of 85 Hz at 1280x1024. It's fairly 
comfortable to the eye. Do you think a LCD would be any better?

> In a way I have no choice,

Yes. And it's hard to get outmoded technology fixed at a decent price. But 
that doesn't nean the replacement is any better. Think about CD vs vinyl 
records. All that can be said in favor of CD, is you couldn't get a good 
turntable for that kind of money. But $400 sould get you sound that you'll 
never hear from a CD. Maybe when 32 bit sound somes?

What are the models, so I can check the specs. Any one that could sell for 
around $350 CAN?

I won't open it up unless I have to. I know nothing about electronics. A 
friend of mine repairs TVs, but I don't think he knows much about the 
peculiarities of monitors.

I'd be interested to know how to remove the high voltage, though. If the 
only choice I have is throw the monitor to the garbage, I'll take a look.

Very true! Surface noise, Distortion, Rumble, Wow and flutter etc. etc.
(But in fact you can hear them all from CD by simply digitally recording the
vinyl record)

Seems this load of old bollocks will never disappear!

I expect he knows enough to avoid the dangerous bits.

After uplugging the mains there's dangeros voltages stored in two main places
inside the picture tube, and in the reservoir capacitors,  these charges
need to be avoided or dissipated.

If the fault is aging capacitors (and not a dodggy joint), it's a more
involved task... Don't ask you friend to fix it for you. (he probably 
gets that line from too may others already) but he be able to give you
some pointers, (and can probably tell your skill level better than I).

True enough, but phonographs have "personality" and some people can't get 
enough of that. I agree that if one does a competent job of digitizing an LP 
to a CD the results do sound remarkably like the original LP. I've had some 
pretty good results copying vinyl to the computer, cleaning up with DcArt or 
CoolEdit, and putting on CD. It's a tedious process though, especially doing 
manual pop - and - click removal. Thankfully more and more of the old music 
has been re-issued on CD anyway.

How do you "dissipate" them? I would have thought it would ne better not 
to unplug the monitor, so that it remains groundes, just turn the monitor off.

 From what I see now, it seems I'll buy a new LCD and keep the CRT in a 
corner hoping that Gawd will send me the messiah. After a year or two with 
no messiah in sight, I'll throw it away.

Or you could take a "perfect" digital recording and add the nostalgic
artifacts with appropriate software.

I suppose one could also simulate a CRT monitor on an LCD by using
software to add a black border, out-of-focus corner regions, vertical
and horizontal linearity variances, pincushion, and colour convergence
problems. One could also simulate EHT regulation issues by shrinking
or expanding the image when the brightness varies. An occasional
simulated HV crackle from the built-in speakers would add to the
nostalgia.

with a resistor having legs. Mine is a pair of 11kW tubular dynamic 
braking resistors (15mm OD x 200mm), with a nice set of fluke multimeter 
leads attached and all inside some nice heatshrink.

leaving the plug attached is a VERY BAD IDEA. That means the chassis is 
live up to the switch. In many modern monitors, its not even a mains 
switch, so the CHASSIS STAYS LIVE. You have been warned.

I'll be quite happy to forego all those problems as soon as a flat panel
display provides better contrast, color saturation and gamut as a good CRT,
at a similar price.
(nostalgia is vastly overrated anyway, even if it ain't what it used to be

I've seen that...  if you know someone who's running linux, get then to
run xscreensaver and demonstate the "analogtv", "pong" and/or "apple2"
screensaver modules. analogtv is the best but the other two follow a 
similar theme.

I'm resisting purchasing an LCD or plasma TV for the same reasons (and
others). The thing I like best about my LCD monitor is its sharpness
and the perfect geometry. My eyes used to water when I had a CRT. Not
so with an LCD. BTW, I don't play games on my PC.

I recently bought one of those DSE 1440x900 LCD monitors. its very nice.

Nor do I play games on my PC. its a tool. I've also had my entire 
lifetime quota of games (my folks owned many, many arcade machines when 
I was a boy, then I worked for 3 years servicing them before getting a 
degree)

I have no intention of buying a fancy TV though - all TV is shit, 
regardless of the picture size.

My eyes used to water with a cheap CRT too, so I bought a decent one. End of
problem.
I also get eyestrain with a cheap BenQ LCD, and it's totally *useless* for
graphics work to boot.
So now I am happy with using a good CRT and a LCD in dual monitor set-up.
A larger flat panel display with even higher quality than either will be
nice when they invent one, *and* the price becomes reasonable. In the
meantime a suitable solution exists for me at an acceptable price. It's not
one that many others choose, but that's their decision.

yep, got hundreds on my last trip to china, at about NZ$1 each.

pissed me off really, when I look at the large stack I already had.

its kinda fun actually, when theres a movie on telly, to say "bugger the 
ads" and slap on the DVD.

I have a 29" telly. any bigger and there is no benefit, as the 
resolution stays the same, so you have to sit further away....

Personally, I leave the TV off unless watching a movie or a good comedy. 
I used to like the news, but the journalism is so superficial it just 
annoys me. but the missus likes

Besides, I can feel myself getting stupider while the TV shouts 
advertising at me.
