How To Fix A Water Damaged Laptop Screen

Yesterday took autonomously and repaired my notebook LCD screen with h2o damage. The screen itself was working just fine but information technology had two dissimilar issues.

– previous owner spilled h2o on the laptop. Somehow the h2o got inside the LCD screen and left stains inside the screen. The water marks were very noticeable on a white groundwork and it was very irritating.
– the screen also had grit and lint inside also very noticeable on a white background. I take no thought how it got in there but I decided to clean it upwardly too.

To set up both bug I had to open up up the LCD screen. This was my start experience on opening a notebook screen. I was pretty confident because I didn't actually intendance if I break the screen, I just wanted to know if information technology's possible to fix it.

Information technology's very expensive. Think twice before you decide opening the screen. Continue at your own risk.
