I was told the second flex cable might be bad cause it the one that closes and opens with the lcd so many times. I tapped on it, i adjusted correctly with the hinge because it was loose but still didn't give good image tho it produced a different glitch more readable, it must be the fault.
UPDATE: I was able to get good image on the lcd panel for several minutes after somewhat straighten the second flex cable inside the lcd panel, now is just a little bad again but not severe bad. What else can i do? I didn't take picture/video is this cable:

video of good image: haven't try opening the panel again but it may break image again after closing the lid.
