Hacking Ds Lite TopScreen

[blackfoxx]

Hi

I own a DSLITE and the top screens been wrecked for a long while. I thought that maybe its time i look into it and try to get a solution.
So this is what my top screen looks like now.

I bought a replacement case and screen. And i put it all together (except for the speakers, I'll put them on tomorrow). But the thing is the screen still looks like it did before(inverted).

So I thought i had the solution when really i just failed. I dont know why it went into this state in the first place. Just turned it on on day and it was like this.

So is there a solution to this? or is my ds just stufffed for life ?

And sorry for the crazy size images...

I don't know quite what they do, however there are a couple of trim pots on the motherboard. I have seen where people have stated that they have improved the picture. BE gentle and turn them very carefully to see if they have any effect, this is the only thing I can think of!
