When your LCD monitor won't turn on, keep it out of a landfill by repairing it yourself for a few bucks. Grab a screwdriver and soldering iron for an easy fix.
My workstation consists of a FreeBSD desktop with dual LCD monitors and a MacBook Pro provided by my current client for anything that requires access to their network. Both monitors had some age on them, so it was only a matter of time before one died. I've used a dual monitor setup for so long that having only one monitor makes me feel... well, half as productive. When my primary monitor finally cashed in its chips a few months ago, that left me not only less productive but also using a very old LCD given that it was my former secondary. I immediately found a great deal on a shiny, new replacement that brought me up to date with a 23.6" 1080p primary monitor. Although I had 2 monitors again, my former primary sitting in the floor waiting to be recycled seemed to be taunting me.
