Sony_Fan Posted August 2, 2011 Report Share Posted August 2, 2011 The directional pad on my MZ-N505 does not work properly. These are the PLAY, STOP, FF, RR buttons in a circular pad. When I push PLAY the unit activates the FF or RR button. The same happens when I push STOP. Is there anyway to fix this? It wasn't doing this when I first got it less than 2 years ago, but now it's annoying and I'm not using it as much. Thanks. Quote Link to comment Share on other sites More sharing options...
jim.hoggarth Posted August 4, 2011 Report Share Posted August 4, 2011 Hi. Standard problem with N505s and N707s. It's caused by flaky key contacts. You can strip the keyboard down, peel back the sticky plastic film which holds the key contact 'domes' down and clean the board contacts with a Q-Tip soaked in a little safe solvent, such as methylated spirits. Usually works a treat. Jim Quote Link to comment Share on other sites More sharing options...

jim.hoggarth Posted August 11, 2011 Report Share Posted August 11, 2011 You need to refer to the service manual for that model, which can be found here: You need to remove the lower casing first (four screws). Remove as if the side with the in/out sockets was a hinge, if you see what I mean. Now unplug the display connector, and remove the two step screws on the side of the upper casing. Note how the spring on the other side is mounted as this will come off. Remove the top case from the chassis, lifting from the screw end. You can now get to the display board screws, and the board just lifts off. Reassembly is the reverse. Points to watch for: ensure the hold switch is correctly positioned when replacing the display board. Refit the hinge spring after you get the top screwed back on. Don't break anything, especially the write head. Replace the bottom case carefully, get the sockets into their respective holes first, be sure the eject button is in the 'out' position before pushing the lower case home. If you do manage to break it, or it seems too much for you, I do a repair service. Jim Quote Link to comment Share on other sites More sharing options...
