Welcome to IWETHEY!

New dead flat panel?
Has anyone here had experiences with LCD monitor failures? My NEC 1830, a handsome 18" jobbie just three years old, lit up as usual this morning (I have been granted two days at home by a benificent boss in return for nights, weekends and holidays spent on a just-concluded project) and then, seconds later, dimmed and went dark. Over the past couple of weeks the display had flickered slightly a few times, and I put this down to erratic electricity, but perhaps these were precursor symptoms.

On the remote chance that the problem lay in the video card, I connected the monitor to this laptop, which can support a second screen, and...nada.

None of the usual hardwired onscreen menus, which would ordinarily come up at the touch of a button independent of the computer on the other end, appear.

When the monitor is powered up it emits a brief, very faint glow for a moment and then goes dark.

It is well that I have the Powerbook to fall back on, but most of my production software is still marooned on the desktop machine, and my palette-heavy applications do not lend themselves to a 12" 1024 x 768 display.

Any chance that this will turn out to be a ten-cent part, does anyone think, or must I brave the harrowing CompUSSR retail experience to restore functionality to my main machine?

New Might be the lamp.
Check [link|http://fixmymonitor.com/|FixMyMonitor.com] in Anaheim. I found it via Google, no experience with them, caveat emptor, etc.

Good luck.

Cheers,

New Sounds like the fluorescent tube.
[link|http://computer.howstuffworks.com/lcd3.htm|How LCDs Work].
Most computer displays are lit with built-in fluorescent tubes above, beside and sometimes behind the LCD. A white diffusion panel behind the LCD redirects and scatters the light evenly to ensure a uniform display. On its way through filters, liquid crystal layers and electrode layers, a lot of this light is lost -- often more than half!

New resurrection!
Aparently the monitor hadn't died—only fainted.

I left it plugged in but not otherwise connected to anything; would stop by at intervals, switch it on, stab front panel buttons, gloomily ponder replacement options. At about the third go-around, half a day after the original failure, the lights came back on. Go figure.

1280x1024, good buddies,

... into the swamp. But the FOURTH one... the FOURTH one stayed UP!

New Hurrah for LCD!
I'm never having a CRT monitor again.

I'm seriously smitten by this here Dell 1800FP. It's big! It's square! Image geometry is perfect! Super-exacto-sharp! It's absolutely flicker free! And it's SMALL! It's 20 centimetres deep, instead of the 60-80 centimetres an equivalent sized CRT display would be; and it consumes a LOT less power.

New One issue
Flicker-freedom is at the expense of slow-reponse pixels. For rapid frame rates you can't beat a CRT.

New That's going away
LCDs are getting faster; I've certainly not been hindered in my gaming exploits by the refresh rate of the FP1800. (It's about 25ms, IIRC. GIYF.)

Sounds like a power management issue. Because ACPI was invented on the planet Stooge by evil dwarves, sometimes devices go to sleep and don't wake up.

New Flourescent tube + PS
As others noted - this seems most likely failure, rather than the TFT matrix, drivers. Might be worth finding out how to field strip to where you can see exact mfg. and model silkscreened on the little inverter card. Each card expects an exact lamp match and lots of effort has been spent to get these juuust-right - particularly for portables. So usually you buy the combo, not just bulbs - the PS is cheap and surface mount = nobody tries to repair that.

I think.. there are only a few (Asian) suppliers - whose latest design is gobbled up by the Big assemblers. Alas, I don't remember hearing an ez method for getting the part -- but it was deemed lots cheaper than ordering from Brand-X reseller (NEC, HP et al).

It is possible to buy just the tiny/long tubes, but a bit messy to physically replace; also likely harder to order bare, at 1 ea. (This stuff is prolly on web)

At 3.00 years - I'm betting your warranty died - which sent the kill signal 1 hr. later via a passing Fatherland Security Home Purity Watchmobile.


Luck,

I.
