I've had a problem with my sp5 for the last couple of months where the joystick was slowly becoming unusable. It would hardly ever work in the up direction at all, and wasn't great in the down direction either. I had tried cleaning the joystick from the outside, but that made little difference.
Tonight I tried following your disassembly instructions, and then cleaned the joystick and the keypad and put it all back together. Now my joystick works beautifully, but only half the buttons on my keypad work!
From memory, the Home, back, dial, hang up, 3, 4, 7, 8, * and # buttons all don't work.
The disassembly and reassembly process all went fine. I didn't damage the keypad ribbon cable and I have checked several times that it is connected to the mainboard correctly.
The buttons all click nicely and their action feels and sounds like they should be working ok.
Can anyone suggest anything I can do to fix this?
