2015 MBA display issue

Hi, I have a 2015 MBA 820-000165 with a display issue. See attached. Now to me this looks like an LCD fault. The device boots and chimes. I have done the usual SMC and NVRAM resets. I have removed the Logicboard and there was corrosion around Q1840 and U7840 which I have cleaned up with some Isopropyl Alcohol. J8300 looks fine. I don't have a known working screen so I was hoping for some feedback on this before I order a new display.

Looks like bad screen.
What about external video?

Hi, works fine on an external screen.

I have ordered a new display. I will update the post when I have installed it.

Hi, the new screen worked a treat. Thank you.
