Laptop Screen is Brocken and keyboard is damaged from water spill

Hello I have a Lenovo y50 and I have two issues at the moment one is my screen is Brocken with white lines on the side that move toward the middle and I think the best solution is to buy a new screen for my laptop. But I don't know how

Or where to buy it

My other issue is that a around 6 months ago I spilled water on my keyboard I was half asleep and I tried wipi g it off but fell a sleep before checking anyway now my laptop has some keys that won't work and there are keys that I think short circuit and keep being pressed without me pressing them, a work around isi bought an external a keyboard and after I press the delete button on my laptop then I can use my external keyboard just fine I don't know what to do to fix this problem

I appreciate any help and sorry for the long post also I don't live in the USA so I would like to buy and ship from eBay
