G3-571 Laptop doesn't turn on when LCD wire is plugged in?

VirmanaVirmana Member Posts: 17 Troubleshooter
have an acer helios 300 g3-571 model and my laptop doesn't turn on when the LCD wire is in. Just a blue light appears for 2 seconds along with fan noise then switches off. Yesterday the laptop suddenly turned off without notice and i spent all day trying to figure out why. I decided to take wires out one by one to perhaps find a culprit, it turns out it was the LCD wire!!! Now i'm using a smart screen tv to type this, so dumb. What can i show you now that the laptop is on, something that might pinpoint the problem..
Event viewer shows a HAL error about 13 seconds before the first shutdown "The iommu fault reporting has been initialized." and windows says the shuttdown was unexpected.
