Touchpad help before buying replacement kit

[merenguele]

Have you tried to make a software update? Are you sure that the cause of the malfunction is a bad wiring? When you say that the motherboard of the buttons maybe bad I don't understand you. There is only one main board. Have you dissassembled your zen vision m? Have you checked that the flat wire from the buttonery is securely connected? Once I dissassembled my zen vision M and I thought that I broke the screen but it was just that I didn't push firmly enough the screen wire!
Please, tell me more so I'll try to help.

PD: I watered my zen and managed to repair it after making several try and error!
