@ven9700 you are not really telling us a lot here. Let's start with your screen. First you want to connect an external monitor. If that displays correctly then you know your GPU is okay.
You can now focus on your LCD display. You need to measure the voltage on the display connector. The backlight will be anywhere in the mid 20V to high 30's Voltage. You need to find the motherboard number usually printed right on the board, so we can determine which schematic you need. Yours could be a MS-15821/MS1582 but again there are different boards out there for this. It may also not be available, which could make things a bit more difficult. Then you need to figure out what pin on the connector is your backlight. Then do the voltage check.
If the voltage is normal, it is your screen, if the voltage is the same as your system, it is your LCD boost circuit. If there is no power it is either a backlight fuse or the WLED driver circuit that has failed.
So for now, there is no clear answer since we do not know what board this is etc. Pressing on the keyboard really only puts pressure on mostly the battery, so I suggest that you check all the cable connections as well.
We'll get to the WiFi etc. after we fixed the display :-)
