My dslite screen stopped working properly. stylus was not responding properly so i ordered a replacement screen. When trying to replace we realised we had an bottom LCD screen and not the touch screen so could not continue with the repair. When we put everything back together both screens now flicker. After this i did try connecting just the new LCD screen and this did not resolve the problem.
Do you think its now a problem with the main board ?
I finally solved the flickering problem on my DS (!), after I made my 1st engineering attempt overhaul shell, top screen and broken right hinge. Was really frustrated about the flicker afterwards, and opened up unit back up too many times to debug (risked damage to cable ribbon everytime!).
Anyway turns out there's 2 hidden screws (location: inside the battery compartment near where the front 'volume slider' is located) that adjusts the flickering (like how you need to calibrate an LCD monitor from doing same flickering effects) . You'll need a really (really!) small philips (+) screwdriver to do the adjustment.
Open up the battery cover with the VOL label upside down & facing you. The adjustment screws are recessed deep inside the plastic...a right and left screw. With the DS turned 'ON' to see the screen (whether you twist your neck to be able to see or have a mirror on the table in front of the DS)....slowly/carefully turn the screws to adjust until you like the clarity. That's it. The right screw = bottom screen. The left screw = top screen.
Now.... on to figuring out how to replace or fix the broken Power toggle switch that I snapped off! Currently using the toothpick method, but that's getting old! Any suggestions, I'd appreciate it!
Votahuan is completely right.
this will not fix a broken screen or a damaged ribbon. it's most likely that you turned one of these screws while trying to remove the back cover, and you just need to readjust it. they do not hold anything down, so remove your back cover. looking at the board with the dscard slot at the top you will see two tiny silver philips "screws" to the left and the right of the volume slider which is in the bottom right of the board. these are what he was talking about. one controls the flicker of the top screen(left when you're looking at it as i said) and the other the top screen. dont worry about adjusting the wrong one, you can just adjust it back. for those of you who know where they are already, you can access them withour removing the back cover. they're in those deep recessess in the bottom of the battery case.
Open the battery compartment and take out the battery. There are two screws which were covered by the battery. Loosen the one near the middle of the battery compartment. Try one quarter of a turn at a time.
Worked for me when I replaced my case and was really annoyed to find both screens flickering. Glad all it was was an over-tight screw.
Follow up to my previous solution - This didn't fix it the problem although I've now found out the cause.
In the left hand hinge there is a metal split ring - The cable for the top screen was catching in the split in this ring. Lucky for me it hadn't damaged the ribbin cable.
All I did was rotate the split ring round a bit until the cable couldn't catch in it.

Get it reperd
Tightening or calibrating the two screws under the battery will do very little. One holds the case the other holds the circuit board. Good luck to those it worked for but its probably a loose touch screen connector.

the lower screen is not responding to the stylus on my ds
my dtr's DS Lite started flickering on the top screen, any suggestions. It is 2 years old-out of warranty?
I had the same problem, after replacing the shell of my old DS lite, the lower screen was flickering, it was bothering me but I saw one of the answers here and solved my problem completely.
All I had to do was to lightly turn one of the screws under the battery cover, the right one.
Thanks votahuan.
