Change point detection in sequences of functional data is examined where the functional observations are dependent. The theoretical properties for tests for at most one change are derived with a special focus on power analysis. It is shown that the usual desirable properties of PCA to represent large amounts of the variation in a few components can actually be detrimental in the case of change point detection.
