Not blue. Just dead. My laptop LCD screen is trying to off itself. I have backlight at the moment, but I don’t know when it will cut out again. Looks like replacement is around 500 dollars. Blargh. Pretty much have to wait till I get back to the US to do it anyway.
Model: IBM T42 Thinkpad
Symptom: Intermittent loss of screen backlight. Restores briefly after boot or sleep. Previously showed pink hues immediately after boot/sleep that would fade over time.
Google says: Common-ish problem among same model laptops, most likely problem: LCD screen is shot or some sort of inverter needs to be replaced.
