After I swapped the game card reader, when I powered the switch back up the switch constantly moved and clicked randomly. Basically it was unusable. But it does work when I put it in the dock and use it on a tv. Any thoughts what happened?
First, is it working now? If it is it could have been a software bug. If not, try turning it off and on again.
The digitizer connects through the game card slot, so either the connection between the game card slot and the board is bad, the connection for the digitizer ribbon is bad, the game card slot is faulty or the digitizer ribbon is damaged.
