My Nintendo DSL upper screen is very dim/very dark compared to the bottom, so I replaced it. However, it is still dim.
So I dropped my NDSL about a month ago and it would not power on. I took it apart and figured the L2 fell out of place. So, I soldered it back on and everything seemed OK, except that my upper screen is now totally darker (perhaps one-half or less than one-half as bright) and very difficult to see. It's almost impossible to play games like Final Fantasy IV or really any game that mainly depends on the upper screen.
So I figured that I should get that part replaced, which I did several weeks later. Now I think I did the replacement right, as my DS powers on (both top and bottom screens) and the sound works fine, but the darker upper screen issue persists!
Oh, and furthermore, after I replaced the upper screen, there seems to be a row of lights trying to come through at the bottom of the new screen... they look like four brighter, more "normal" (as opposed to dim like the rest of my top screen) spots of light that weren't there before.
Now, I'm guessing my screen is fine, and the problem might be something else...
Anyone have any ideas?
Please help :)
