Hey everyone, I really need some help troubleshooting my laptop. It went from overheating to completely refusing to boot after a cleanup.

Here is the exact timeline of what happened:

1 (The Original Issue): The laptop hadn't been cleaned in almost 2 years. It started instantly shutting down after about 1 minute of use due to severe over heating.

2 After taking it to a technician for a cleaning, I turned it on. It stayed on for a bit, but then the screen went dark. However, when I shone a flashlight directly at the screen, I could faintly see the Windows display still running underneath! The normal screen brightness came back after about a minute.

3 (Current State): Now, the laptop seems completely dead. The screen stays 100% black (the flashlight trick doesn't work anymore). I honestly can't tell if the laptop is actually on or off because the fan will randomly spin up for a few seconds and then turn back off, but nothing else happens.

Ps. Used ai for writing this because my english is not good.

What I think might be wrong:Since the display backlight died first (the flashlight phase), did I accidentally damage the screen/LCD ribbon cable? Or did a reverse current from cleaning the fan finally kill the motherboard's power management chips?Has anyone dealt with this specific sequence of failures? What should I check or replace first.
