JJtodooficial looks like you would need a new battery for sure as well as a new screen. The glitch is most likely the screen driver on the display itself. Contact service could be anything from a missing Sim card/connection to multiple other things. I would worry about that last. You can either use this SM [document|27220] or use the guides on here [[Topic:Nokia 6102i]] The 6102 is very similar to work on.
