Is this under warranty?
No, like I said in the description, the warranty is up.
the issue can occur if:
1 There is a loose connection between the video cable and the LCD screen. 2. Defective LCD screen. 3. or the Defective motherboard
Most probably it is due to the loose connection between the video cable and the LCD screen.
Should I dissect and fix myself, or does it have to be soldered?

You will get a fair idea:
No, there is no need to have it soldered
If you are comfortable doing that, you can do it.
Or ask an hardware expert it do this for you.
I hope you will be satisfied with this information.
