Hi!

 

My old Eee netbook has suffered from water damage. A clumsy mistake on my behalf. Anyways, I thought I'd give it a try. It seems damage is isolated to the LCD screen. There are these ugly marks you know, classic LCD damage. So, I've unscrewed the behind, giving me access to the actual TN panel. It seems the actual stains is not on the actual LCD, but on some sort of protective sheets that lies directly on the LCD. Actually, there's no less than 3(!) film sheets on top of each other. Now, I've removed them all. I will try to clean them with isopropanol. Anyways, I might have forgotten in which order the three sheets were arrayed. Does anyone around here have actual experience in this field? Anyone who could tell me the importance in putting the sheets in the correct order? Two of them seem to be semi-glossy and like giving you a weird view when you try to watch through them, and the one that I believe was closest towards the actual screen is simply matte. All three were behind the TN panel, not in front of it. As a side note, is isopropanol a good method for these film sheets? I assume tap water is not such a good idea.

 

Cheers!
