    Question Galil DMC-2143 - Red LED

    Hi everyone!

    I mistakenly applied 10.7V to the pin 63 (Reset) instead of sinking it to 0 (zero) volt, for a split second. Now the red LED is ON all the time and I can no longer communicate with the board. However it still has the same voltage reading that it used to have on all the 96 pins, except the X, Y, Z & W Amp Enable. Which makes sense: If there is a fault, all the axes should be disabled...

    The reset pin goes straight to the IC U35 (see attached picture). Could anybody help me find this IC? It is smaller than a grain of rice and appears to be made by Texas Instruments. Since I overpower it, I will replace it first and go from there!

    Any help will be greatly appreciated!
