Hi, was browsing Facebook when suddenly a white screen was shown across my entire monitor. Pressing power button won't help or anything, so I plugged off the power adapter from the laptop.

Now it won't boot, just black screen with nothing on it.

Tried:
1) disassembling and reassembling
2) test rams
3) removed hdd
4) unplug power, battery, 30 sec hold on power button
5) plugged in external monitor

All the above ways were tried however still no solution to the problem. It's a Dell Inspiron 14 series which is around 5 years now.

Any help would do, really appreciate any replies from anyone. Thanks in advance.
