Monitor problem with vertical stripes and Black Spot

[luizcrfb]

Hello, when turning on my monitor, I came across this situation:
black ρá†ch at the bottom
vertical colored stripes
A lower right region with an intensely bright light spot.
The monitor has not been damaged in any way. I simply turned it off one day and when I turned it back on, it was like this.
I tried to clean the flat cable with an eraser and anti-seize, but without success. In fact, the situation got worse as more stripes appeared.

Any suggestion to solve this problem?
The computer in question is a Dell Optiplex 3030 A20 All In One.
The monitor has an LG Lm195wd1 display
The flat cable is cn-00Rt13 70163.

mostly for experts na yan
pero if gusto mo makipag sapalaran
if marunong ka mag hanap ng CKV lines
pede mo i trial and error yung pag cut nya either sa left side or right side
