Hi.
Ever since I have updated my mac to High Sierra this problem seems to occur constantly and there were few steps eventually forcing me to write a question.
1. Kernel panics occured suddenly. I then deleted few programs not compatible with High Sierra, which solved the question.
2. When I turn the mac on, I hear the chime but the screen stayed black.
I just force restarted the mac few times and it worked.
3. I use Safari as my main browser and when I enter streaming websites such as Twitch, the screen just goes black and I will have to restart the mac again.
4. Now when I use Safari, the screen goes black in 5minutes. I have tried using Chrome as a substitute, which immediately turns my mac off. Funny thing is, there is a 50/50 chance my mac crashes when using Safari and Chrome.
5. I tried using external monitor to see whether I can se the screen when the screen goes black- It does not work. When the screen is normal, the external monitor works. But when I try to enter Mission Control, the screen goes black, and so does the external monitor.
What my mac looks like when the screen goes black-
Keyboard makes noises.
The Apple logo does not lit up on the front panel?
The external monitor does not work.
I consulted a guy at the service center and he told me that they will have to clean install the OS completely. So I did manage to backup some important files(I was not able to transfer files to the external hard drive so I had to use a cloud storage)
And I tried to clean install the OS myself. The problem is, there is a 50/50 chance for me to enter startup manager, and when I do manage to select "Install High Sierra", The loading bar stops in the middle and I then hear some metallic spinning(Maybe a fan noise since I use a ssd) and the screen goes black again, followed by occasional kernel panics when I force restart the mac.
Other than that, I have tried smc, pram, recover mode but they all endup in a similar situation.
Before I had the High Sierra update, I accidentally dropped my mac once which damaged my screen badly and had to replace the front panel completely.
Is there any possiblity that the damage also affected my internal parts as well which is creating this situation?
And can I have a rough idea of what internal part is causing this problem?
