bottom screen problem, (very strange)

My sons almost new ds lite bottom screen appeared to stop working properly, almost as though no backlight it was very dark and flickery and looked as though the resolution had dropped down. I replaced the screen with a known working one and the problem is still there! you can see the screen and play the games but it is not easy, apart from changing the motherboard is there anything else i can try?

 

You say almost new, so is it under a yr old.
I would just contact nintendo then and send it in.

 

not that easy, it was a special edition one imported from hong kong and the seller is not interested

 

I believe there are 2 trimming pots - be very careful as I have never used them but I have seen where others have solved flickering ect by moving them. I would suggest moving each on a tiny amount up and down and see if it has any effect. Sorry I don't know any more info but hope it helps

 

well I had my hand forced!! the other son broke his ds (3 years old) snapped hinge! so i bought a new ds and gave it to the second son and then took the motherboard out of the ds in two bits and fixed the first one, thanks for the advice kittymat, ive spotted the two trimmers and after ordering up some hinges and a ribbon cable ill give it a go and see what happens, I may end up with one for myself )
one last point, im told that the wifi also had stopped working on the ds with the screen fault but changing the wifi unit didnt fix it (
thanks again all who gave help
