Possible laptop backlight issue from spillage
So 2 years ago I accidentally spilt pepsi onto my laptop. It still works perfectly except for the screen being really dim(can still see if bright light or if I flash my phone torch) and the keys a bit stiff. It works when I have it plugged into a monitor so the issue is with the actually laptop screen itself, is it a backlight issue? I bought a new pc 8/9 months ago so I'm not too worried but also I would like to have it repaired for travel purposes. Any idea of the cost of repairing or if it would be cheaper to repair myself? Laptop is a Lenovo IdeaPad 3 15ITL6
