• Monitor dying in weird way
    6 replies, posted
So my still fairly new IPS monitor just started dying on me (ordered it last year) but its doing it in a really weird way. Half the screen is darker and "pinker" than the rest with a kind of rolling disruption pattern that makes it hard to read small text or smaller details. Colors are off and it fades to perfectly fine halfway through the screen. Its exaggerated a bit by this photo, but its close enough.

Any help would be appreciated, I'm broke as fuck at the moment so if I can't figure this out I'm waiting 3 weeks for online deals to get a new monitor or two (or if you know of any current deals, please let me know).
My LCD died after 6 years last May, seems weird that yours is dying after only a year. You might investigate and see if your warranty is still valid. Otherwise my advice is to just stick it out until those deals come along, the monitor I have now is really nice. [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16824236174[/url]
Yeah, seems so. I also tried a DVI cable and every other dvi plug on my computer, including the motherboard slot. No dice. Fucking sucks man
It looks as though a broken color profile might be getting applied or something. Have you tried using the monitor on a different OS than your main?
It started showing up at login screen now, so I don't think thats it but I'll try it with a flash drive copy of linux
It looks like a problem with the CCFL or the inverter that powers the CCFL, which are common in LCD monitors. Though it failing after only a year most likely means that some part is defective. What's probably happened is one of the CCFLs has a slow leak at the end of the tube and the anode/cathode has oxidized. The oxidation on the electrical element causes the tube to get extremely hot when electrical power is applied, to the point where it can glow cherry red. This causes discoloration on the screen and can burn components in the screen around the CCFL. The other less likely issue is the inverter has failed and is sending excessive voltage to the CCFLs and causing them to burn. Though most power boards on LCD screens have circuitry to detect excessive current draw and shut down, causing the screen to turn off or act erratically. All of these problems can be fixed, but it's usually cheaper and far easier to buy a new monitor. Repairing CCFLs in a LCD screen requires complete disassembly of the screen itself, and it's hard to get the thing back together without damaging it. Replacing power boards is easier, but it's not always possible to source replacements.
I'm trying for warranty now. In other news, when the world pisses on you it REALLY pisses on you.
