Grateful how? Neverminding that detail, perhaps your screen's backlight or the power supply for it has failed. There's nothing to do but compare your unit's operation with that in the Service Manual or that of an operating unit; this is complicated by the fact that components might send an OK signal back to the main controller, so removing the bad parts will not necessarily mean the unit behaves normally otherwise. It may be as simple as rinsing the cat barf out with water and D.I. water (but you would still have to open the thing up on towels to find out.)
Of course the main power supply might also be faltering. you can probe the supply (with a DVM or scope) to see how steady that is.

It is the Monitor Cable connected to the CPU cabinet is faulty. Please check out the cable and its pin firmly.
Try to find the fault, may be the cable broken or tear up.
Let me know if further diagnose required.
Have a nice day.

I have a problem of opening the casing of my LCD Monitor, I want to open it so that I can visually check inside.

The first thing to check is the power supply to the monitor. Mine went a while ago, black screen nothing happening, turns out it was just the power supply. A quick search on your favourite browser will probably turn up a supplier, I found one that just makes monitor power supplies, so it must be a common problem!
If you have a meter test the power coming into the monitor, or if you're unsure put it to your ear when its plugged in, you should hear a faint buzz which means its working. Also check for any breaks in the cable and/or if there is a fuse in the plug which might have blown**
**If a fuse has blown, it might point to another problem, but at least it's a starting point
