I have tried unplugging and re-plugging the remote multiple times and done everything I know how to. On occasion it will let you move other directions but then it will start going straight up no matter what. Are the Potentiometers in the D-pad damaged or might it be the micro chip. Mine is the kind with the blue face and the clear back.
Michael Stucki, the first thing I would do, is to clean it. Use this video as a guide. After that, re-evaluate and see what you got. The drifting is usually not part of an IC control. I found that if any IC goes, there is no movement.
