So I came home one day to find my old LCD monitor would turn on for a couple seconds and black out. If this sounds familiar, try shining a light at the monitor. If you can see faint outlines of what the screen is supposed to be showing, congrats your backlight is probably broken. Here's what you need to fix it:
Broken LCD monitor
BTW: a lot of the times popped capacitors will effect the monitor in different ways. However, if your monitor stopped working in a natural manner (ie. not you punching it in rage) then more often than not it is because the capacitors are broken. Therefore, this tutorial will still work=D
BTWW: dont open CRT monitors unless you know what you're doing...but then you could probably skip reading the rest of this tutorial; they contain much larger capacitors and a new monitor is worth it. trust me.
Step 1: Opening Your Monitor
First step is pretty simple: attack the case with a screwdriver. Since different monitors open in different ways, I can't say much about your's. If you really are stuck trying to pry that case off, before you decide to break out the hammer, try a quick youtube/google search of your particular brand. Tip though, take pictures of all your screws like the pic attached. It'll save you much agony and humpty dumtying later on when putting it all back together again;D
There are a couple wires you may have to unplug throughout the process, and again, picture help a lot especially if you have adhd or like doing a million things at the same time.
IMPORTANT: As you reach the motherboards of the monitor be very careful where you touch. Inside there are often large capacitors that can potentially give you unpleasant shocks. To make sure they are discharged properly, use a screwdriver with a rubber handle and connect the two leads of the capacitor. Chances are it won't do anything, but safety is first as always.
