1 - 4 hours
The monitor backlight suddenly went dark. first i could easily relight it by turning the brightness full down and then up again, but it went worse day by day. the backlight kept working if i pulled the right upper corner of the monitor towards me and pushed the left one back. well, paperclip + rubber rings did help for some hours, but that wasnt really a solution.
as said before by others, most of these problems are due to faulty backlight converters or -cables, but mine wasnt. wasted some money on them plus a set of display bezel clips, well, sort of my own fault oO but i felt them going bad fast also when i treated them the best i could.
another order anyhow brought me the new lcd and that finally fixed the problem. but i had to go through most of the guide one more time as i had first connected the backlight cable inproperly... --> very harassing, got me almost close to a nervous breakdown but luckily it worked in the end.
the new lcd now has a way cooler color spectrum which took me many many rounds and felt hours of calibration until the result was something close to pleasent
a funny by-fact was that the lcd came while i lay in hospital for an orbital enucleation and dermis fat transplantation so i can have a glass eye in the next weeks.
1st: be careful with those display bezel clips and read the guide on how to do the remounting before messing around yourself. they're 20$ 12pcs which is definitely not worth the fun!
2nd: dont know how to advise on that one but including inverter+cable, bezel clips, lcd, shipping costs and taxes i paid close to 300€, which are quite a bigger sum in US $ and could easily have had me a full display mount including a brand new and perfectly mounted bezel...
but it seems like everyone with this problem has to go through the same steps since most of those problems might be caused only by the inverter thing.
