When you connect the charger, is there any led light turning on in the laptop body? Front or side?

That indicates error code related to hardware failure. Most likely motherboard

You can start by disconnecting all devices of the motherboard:
Wifi card, keyboard, mouse, other boards, RAM. also disconnect all cables: LCD cable, etc any cable.
Everything
Connect charger and test
If you get a solid light (locate that the led indicator cable is connected), then your motherboard is good, so connect devices one by one to find it which is bad.
If you do get a led error code then the MB is bad
