Xpantastic!

i have a xpander , not hard to open.. they are the big main board, psu board , and other board for memory, control on cover ..pcb board are hold and fragile, some component are fragilising by the time, some should not be tuch like some "mosfet" component.take all your time, calmly, with all precaution, put power cable 110v / 220v out. all voltage wire/ slot coming from psu to alimenting different boards should be reconnect before you put back power supply on .psu card have to run "on charge" otherwise it can be damaged as technician tell me.. they are some post on internet about intervention maintenance for display, rotary encoder, button zone ..bie

     It sounds as if the front panel is slightly out of line with its switch 
holes. Just loosen all the panel mounting nuts on the inside, just 
enough to allow a little free movement of the pcb, and shuffle the board 
around gently until all the buttons are free switching. Then finger 
tighten a couple of the nuts to hold it in place. Recheck again and if 
all it good, tighten them all up again. Recheck again and repeat if not 
successful.
