Tauboid :
I'm trying to dismantle it, but I can't seem to get past the front bezel, it feels af if I'm gonna break it... Also it looks to me that the screen is being held together by steel.
Yes, front bezels are a PITA to pry out and you will most likely break a few of their clips in the process of getting in unless you know the clips' exact locations and how to pry them apart to avoid snapping them off. If you do decide to give prying the bezel another try, keep in mind to have some duck tape ready in case you break too many tabs for the bezel to hold the LCD in when you put it back together - in the displays I have opened, the bezel is practically the only thing preventing the panel from falling out.
Taking the display panel sandwich apart to remove the bugs is going to be a delicate operation. You may end up replacing the bugs with a much larger number of dust particles and if you are unlucky, you may also knock the filters out of alignment with the LCD panel, which may ruin your day assuming it did not get ruined already by breaking something during the disassembly/reassembly process.
So yeah, don't bother taking it apart unless the bugs bug you enough to feel like chucking the LCD out. This way, you aren't really losing anything if the surgery fails.
