LCD monitor goes bang

[slofox]

Well, not bang, but appears to have lost its light - my first thought was "backlight is dead".

The I thought, "Hey! Those KB blokes and blokesses know everything! I'll ask there!"

SO here it is...

I'd been away from the screen for several minutes and came back to a black screen. Switching off and back on, rebooting computer etc all resulted in a brief but dull display that dies after a few seconds.

Swapped to an old CRT which is doing service at present. Works fine. Tried the LCD on the shop security camera with negative result - same as above.

Sooooo all computer whizzes, wotcha think? If it is the backlight is it just a matter of changing the tube?

Monitor is Viewsonic VX1940W.

What size hammer have you tried so far?

don't think tubes are changeable, sounds more like an inverter failure though, may be changeable, probably cheaper/easier to get a new one

No hammer yet - didn't think of "percussive maintenance"

Too much pr0n.

Is that like too much money? I've heard it exists but don't think I'll ever see it

You work there eh?

Nah, they're just GC's to deal with

[riffer]

Most likely a capacitor. LCD screens are notorious for it.

Agreed. I have had lots of dealings with them and they have done pretty well for me.

What sort of power lead or pack does it use? Philips monitors use the standard lead, very error free. The cheaper brands use the packs, which can fail.

Bloody thing is less than three years old...fuckin' crap device. I'll tell Viewsonic to stick it up their collective arse...

[Gremlin]

You has warranty?

[slofox]

You has warranty?

I assume so but I bought it online - probably from some dodgy outfit - who knows?

I will spend tomorrow dredging through back invoices until I find the parsnickular bit of paper...

+1 on power supply caps. Hardest part about repairing them (LCDs) is getting the covers off without breaking all the tabs.

Also with regard to backlight florouscent tubes, it is possible to get white LED replacement strips from E-bay, for the more common brands.

Just a plain ornery lead as far as I can see - no black boxes inline anywhere...

I brought it home to check out here - does just the friggin same. BUT I have found the original invoice...

I'll talk to Viewsonic on Monday. Meanwhile, I might just buy another one tomorrow. If Vewsonic come to the party I'll chuck the CRT I use at home.

Are you using windows 7? If so, a recent update caused the background of my PC to turn black and when the desktop is showing, it's very faintm little to no brightness... I assume it's a power option somewhere, although I havent bothered fixing it.

that or the kids did something
