Hello!
The little background story behind my problem is that about 2 years ago my laptop's (Asus F3JR) screen broke (it became extremely dim, I thought it must be the backlight) and so I went to service and they fixed it by replacing the whole panel. I didn't have time to mess with it myself back then and didn't ask much questions, just let them replace the panel, which cost around 150e. They didn't give any longer guarantee than 2 months and you know what? After 3 months the panel broke again, this time I got some kind of colorful lines in between of my screen. Note: the picture isn't of my laptop,but the issue is similar.

I thought to open the panel myself and look at the issue. I then learnt that by pulling the main chip on the back of the panel would remove these lines on my screen

. However the problem was that I already disassembled the whole panel and took all of the layers (polarizers, diffusers etc.). My stupidity allowed me to forget how to put all those layers back together and so I left the whole thing laying around until now.
Now I have found a person who is need in some kind of internet laptop and I said I can give one if only can I assemble it back to function. I looked at some pages which show the structure of monitors but didn't really help me. ( http://www.tradekorea.com/product-detail/P00026959/Structure_of_LCD_Panel.html ; http://www.sonystyle.com.cn/products/vaio/about_vaio/grt40zcp/image/ph_01basic_02.gif) ) Now I ask the Tom's Hardware community to please help me.
In what order do I assemble the panel's layers? (Pictures in the end of the post)
Is there anything special I should note?
What might be the issue with the corrupted chip, that needs to be forcefully pulled down to function correctly?
Where should the backlight be shining at? The reflector glass (Pic.4 at the bottom) at the back of the panel or some other layer? I have a hard time making it light up the display again.
If someone knows where to buy a new panel which fits this laptop (needs to have shipping to Finland), please tell me.
Your help is greatly appreciated!

(First layer taken off; backcover: white and I guess the reflector glass. Those two are glued together at the top)

(first layer, which I guess is a light diffuser. One side of it has a smooth texture and the other is just a tiny bit rough)

(There is two of these layers. In both one side passes the light and the other reflects and has line going in diagonals. On one of these, lines go in a diagonal to the right while on the other to the left. They seems to have no other differences)

(Last layer. Again looks like a diffuser to me. This one has both sides smooth, but one feels a tad more sticky and it has a black line going on its perimeter. I guess this comes to the panel itself and probably its sticky side to the panel)

Hi :)

Lol...that screen is now DEAD.... it will NEVER work again (see my sig)


You need a new screen with the EXACT SAME NUMBER/LETTERS that are on the white sticker on the back of the ORIGINAL screen.... NOT a single letter or number different...

All the best Brett :)
