Here's a video I made repairing my E178FPb and I show how to take it apart. I assume it comes apart the same as yours.

First you take the little rubber covers off of the front of the monitor--I use a dentist's pick. Under the covers there are screws. Unscrew them.
Now VERY CAREFULLY pry the two halves of the bezel apart. They snap together and I find most times the top of the bezel must be pushed inward as you pry the halves apart.

I finally took the monitor apart and found some bad capacitors.. replaced them with new ones and the monitor is working fine.

I personally haven't worked on this monitor, but most monitors are held together with plastic clips on either side of the casing.

After removing the stand and all other screws, you will need to use a small flat-head screwdriver (or something of that nature) to pry apart the clips. Find the crease/gap in the plastic where the casing of the monitor comes together. Insert the screwdriver and gently twist and pry the casing apart. When you hear the first click/snap indicating the first clip has come apart, follow the gap with the screwdriver, prying it apart each time you reach an area of resistance. Do this all the way around the monitor.

Keep in mind that after you open up all the clips, the LCD panel and boards may be screwed either the front casing or most likely the back casing. So you must first unscrew the mounting screws inside the monitor to remove the back cover. Also be careful unhooking ribbon or speaker cables that attach the circuit boards of the monitor to the front casing.

There are about 8 screws on the back of the monitor. Remove them, and the monitor's back panel will come off, then you can remove more screws to get further into the monitor. By the way... what are you trying to do by taking your monitor apart?

there are clips on the opposite end try pressing the back cover inwards

I had a similar problem with a Dell monitor after a power outage. I pulled the monitor apart and found a connector not completely seated. I think that something internal has happened to your monitor. It could be an internal fuse or something. If you don'r feel comfortable taking it apart, find a reputable service center.

It is clipped on, or there is a hidden screw underneith a sticker or something.

They make these things hard to disassemble for a reason. There is very little you can do one you've got it open. There's almost nothing inside that can be serviced by any normal user.

The front and rear of the case is held together with latch and hook type fasteners, this is how I cracked mine apart.Remove the 4 screws holding the stand on the back of monitor, start with either bottom corners and insert a flat head screwdriver or similar soft object such as a wooden popcicle stick into the crack and work your way up the side to the top, then across the bottom, and up other side to top, I then ease the case apart at the top with no effort.
