X1 Oscillator & shorting?
 i have a dead a500 rev6a board.the X1 OSC has been hacked out looks like board has been damaged put new one in no joy when testing continuity it appears 3 of the pins are connected? 1 4 2 3 (looking from top of board 1,2 and 4 all appear to be ground (buzzes out continuity) i think 4 should be 5V ? Pin 3 in output of the 28.xxx pulse? any advice/thoughts? am i right with the pinout? etc shorting coming from board damage underneath? |

Pins 1 & 2 are ground, Pin 4 is VCC +5V and Pin 3 is 28.x MHz Frequency.
