I instructed him to try the following: Try pressing down on the area below the LCD but above the keyboard, while turning-on; this may work, and if so, it will be necessary to press down on that area while using many keys along the edge of the machine. There is a common problem with older 48 machines where the foam used internally to maintain pressure on a keyboard connector has worn/dried-out. This can be repaired by opening the machine and replacing the foam, and usually everything else is fine. Assuming this is the problem, you can find instructions on how to open a 48 case in many places, including several here in the archives. Adam Jones here on the forum (aj04062) can do this 48 keyboard repair if you aren't handy or if you want the machine to appear untouched after the repair. All that said, why not get a 48GX? Many folks like the color-scheme of the SX better, but the GX has unquestionably better f/w. My solution was to get both. --Bob Prosperi |
