The screen of my ASUS Notebook ROG G750JX started flickering a few days ago.
This is the situation:
It starts flickering after the computer has been turned on for a while. If it's been shut off for hours, then it starts after 30 - 60 min. If I just leave it turned off for a few minutes, it starts after maybe 10 min again.
The whole screen jumps up and down, being displaced by around 1 cm. This is when using 60 Hz update frecuency. When using higher frecuencies, the screen doesn't jump anymore - it stays firm, but shows double and highly unreadable. Still always with the same aprox. 1 cm displacement.
All parts of the screen flicker (Windows 10 start button, Task Manager), and in all cases (during startup, in safe mode etc).
I opened up the laptop, disconnected the screen cable going to the mother board and connected it again, with no difference
The CPU and GPU temperatures are not related with the flickering (they've been at 45 C and screen is still flickering).
When connecting an external monitor, it never flickers, while the laptop screen may be flickering at the same time.
Before the flickering gets too bad, I've seen that it may be flickering differently in different apps. When looking at the desktop background, it may stop flickering, but when opening up the web browser, with a webpage with a different background, it may start flickering again. The same thing if I switch tab from one page to another with different backgrounds, the flickering sometimes may act slightly differently.
All this leads me to believe the problem is inside the actual monitor of my laptop, probably after some part inside the monitor has heated up a little.
What part of the monitor may it be that's causing this? And is it possible for me to open up the monitor and fix it, or is all of my monitor suddenly junk?
Sorry about the misaligned list. The flickering is too bad now for me to fix it because I can't see anymore and I have to shut down hahaha =).
