Question Weird display behavior (might be broken?)

[vistagamer6969]

Hello!
So a few days ago I found my first laptop ever (fujitsu amilo li 2727 ms2228) and when I powered it on it showed me a black screen with 2 white vertical lines and a small white spot in the right down corner. I remember some years ago when I powered it on it did the same thing and I haven't used it since then.
Now when I try to connect it with my 1080p monitor through a VGA cable I receive a message on my screen saying "Cannot display this video mode, change input to 1920x1080@60" or something very similar and obviously I can't do that so I decided to swap out the integrated display to see if it helps and it doesn't...
Now I really want to fix this problem but I don't know what component should I change. The display wasn't used too much as far as I can remember.
Should I try changing the display? Could the display cable be faulty (it happened in the past)? Could it be the inverter? Even the motherboard's video chip could be faulty but I really hope it isn't the case...
Monday I was planning to go to a local service to ask for some help too...

What gpu it has, these series have alot of faulty gpu chips

EDIT: when you move the screen back and forth or try to push from back of screen (where cable is) you get any difference on the picture ?

Man, it's been a long time since I didn't use this machine but as far as I can tell it has a x3100 from intel and T2310 as a processor but I didn't had any problems with the motherboard tho.

I'll try and come back later
Also thanks for the reply

Well here I am...
I tried connecting again the display to the motherboard and the problem still persists but now the 2 white bars are now black which makes me really think the inverter is dead.
Interesting fact: When I power on the laptop my display is white for 3-4 seconds and then it slowly fades out into black.
I will attach some photos to see what I'm talking about.

So... 2 weeks later I'm back.
I bought a second hand inverter from a guy and it doesn't work at all. The screen is completely black, not even a weak light, which is weird because the guy said it tested it and it worked. The codes on them are the same tho.
When I first got it I plugged it in the wrong way, I mean the pink and white were inversely connected on the inverter. Well kind of because it didn't fully connect but by the time I realized the laptop was on. This might have an impact, but when I tried with the old one again it did the thing you can see in photos...
