I'm looking for recommendations for a new monitor... my ViewSonic
croaked last night :-(

Borrowed the wife's, so I need a quick answer ;-)

Thanks!

Get one with LED backlight. They stay very cool.

Yep that was what was wrong with both my ViewSonic's, CFL backlit :-(

I'm considering this one...

CFL? Compact fluorescent? Or do you mean EL? I don't pay attention to
what lights up my display -- it's just magic.

Chances are high that it wasn't the light emitter that broke down, but
rather the wiring or the electronics -- meaning that if it'll break with
the current technology, it'll break with LEDs, too.

Do not get a Samsung. They do not seem to be able to handle
constant usage. I've had 2 die after about 18mo. My latest
is a LG Flatron 22" LED backlight.

I've had very good luck with the Dell Ultrasharp series.

We got three of these at work, they are pretty good for the price. 16:10

I hear the common failure with LED backlighting is loosing a string.
resulting is a square portion of the LCD without a backlight.

You mean 'CCFL backlit'. Cold Cathode, not Compact.

I would try to repair it...
You gonna need the money for food after the collapse of the US economy
brought about by the Obanana & The Demonrats band.

Last year I bought a Samsung 46 inch 3D TV,
it is crap, but the picture 1980x1050 ? when connected to the PC,
is good for those with bad vision, I mean at that size your diagrams are BIG.
But it consumes 200W (CFL backlight).

My 1680x1050 Samsung SyncMaster 206BW monitor works OK for all stuff.
Recently repaired it by replacing some electrolytic in the power supply.

Read some reviews for the monitor you want to buy,
may save you problems.

What is the failure mode?

If you try to turn it on, when there is an active video signal, does an
image display for a half second and then go back off?

If so then there is a high degree of possibility that the problem with
the monitor is easily repairable. The manufacturers of monitors use
really crappy electrolytic capacitors in the power supply and over time
these are either drying out or bulging to the point of venting.

I've repaired a slew of LCD monitors, including units from Dell,
Samsung, LG, Viewsonic, NEC, Planar, and Sceptre that had this problem
and were repaired with a handful of replacement capacitors from Mouser
costing $6 or $7. The replacements restored the monitors to "works like
new" condition!!

As a matter of fact, the problem is so common that a cottage industry
(web style) has popped up with folks selling capacitor kits online. You
give them the model number of your monitor and they will sell you a
small bag of caps to replace those in your monitor. There are even some
web sites that show photos - step by step DIY instructions - for opening
up a monitor and replacing the capacitors.

I had the same problem with my Samsung 931B. It seems to be common even
in Samsung TVs. Radio Shack had the required electrolytic capacitors on
special! It took 15 minutes to pry the case open and 5 minutes to repair!

The problem with Radio Shack parts is that, past generic specs, you
don't really know what you're getting and you're better off going to
Mouser where a proper data sheet is readily available.

In particular, for this application you should look for low ESR,
unless you don't mind replacing them again relatively soon.

The backlight inverter runs large ripple currents so high ESR will
cause excessive heating and premature failure, which is the original
problem.


I prefer the Panasonic FM series from Digikey to any thing Mouser
carries.

You mean these?

They didn't list the FM line when I needed them a while back, and
Digikey was out of stock for over six months.

The other possibility is a problem in the CCFL backlight. My boss
has a pair of Radius screens that started to flicker and go dark, and it got
worse. I opened up the worst one, and the backlight power supply (it had 2
per screen) had the tails of through-hole parts that poked through a mylar
shield behind the PC board and were sparking to the conductive RFI shield
coating on the case. I cut the leads flush and fashioned a new shield for
the inverter boards. These monitors are still working quite a few years
later.
