i assembled the express board and tested it by plugging it in prior to installing the chips and both the 5 volt and 3.3 volt green leds lit. at that point it appeared the build was going well.
i installed the chips, hooked up 2 power cords and plugged them in. i do not get a PRG code on the leds. they dont light at all. when i press the mode button, nothing happens.
there is one led (#6) that always has a faint glow to it when the board is powered up. i can see no bridge on any solder joints, so im not sure why its doing that. if i press RESET, it goes out, then comes back on when i release the button.
if i press the SELECT button, led #16 lights up, then goes out when i release it.
the board will power up when the left side ac cord is the only one attached. it will not power up when the right side ac cord is the only one attached.
the board is terminated.
i dont know whats wrong.
