Hardware DSi XL Ghost touch.

[Unreal2522]

I bought a DSi LL a few months ago and installed unlaunch and twlightmenu++.
While playing New Super Mario Bros. mini games the game pauses constantly meaning the touch screen is pressed. It only stops when I touch it.
I have Cleaned the screen and recalibrated it, and I have the latest version of twlightmenu installed.
I have attached a video of my problem. (sorry for the compression)

Run some hardware checker. If there is ghost input regardless of the current game/software -- since cleaning didn't help -- consider replacing the touch panel
