Help! I think my built-in monitor has timing control problems.

Hi,

I'm having problem with my built-in monitor for about half year, and I don't know what and where is wrong.

I did unassembled my build-in monitor frame and check it by myself and the ribbon cable seems fine. However, currently I don't have such brave to unassemble where my motherboard resides, because it is more harder and I already did some mistakes when I unassembled my built-in laptop, such as chipping my built-in monitor frame by accident and hard to reassemble back for various reasons (such as cables that mounted into the frame being loose itself).

The chronology of my built-in monitor goes wrong is:
1. It is used to be my laptop turned on by itself even I turned it off (don't know why), and always show login screen. One day I noticed, the very topmost pixel got defective, temporarily showing previous colors even it already changed.
2. I did tried to mess with Display options, trying to increase shared system memory. After I quick-check that I can't do it with my hardware and software, I just reset the settings back to normal.
3. The first symptoms. That day, I was login into my computer as usual and entered my password in login screen. Suddenly the monitor got Venetian-Blind like effect and ghosting effect ( First symptoms of my built-in monitor got wrong. - Album on Imgur , check image 1A and 1B).
4. The severe symptoms, my built-in monitor suddenly shows all its pixel on some topmost of the pixel, while the rest shows ghosting effect (I will upload the photo and video of this later, as my phone is at low battery right now.)

Can anyone know and point out what and where is the problem located?
Thanks for answer.
