Nordictrack a2350 When I plug in the treadmill the display comes on then quickly shuts off. Can't figure it out.

Hope the speed sensor have some problem may dust on it or the treadmill need lubrication. Most of the treadmill stop after some kilometres reading indicating that its time to lubricate it. After lubrication you have to reset the counter.
check the link bellow using the search tab find out details of NORDICTRACK A2350. and follow those instruction.

1= Not rexactly, however you must LUBE the deck belt, this a problem because of lack of maintenance, probably a deck worn, this cause enough friction shut down the machine for protection electronic.
2)LUBE the rollers bearing.3)test the input voltage motor, if there are the motor need repair.4) measure the output voltage board, if there are NOT voltage, the board is faulty, see my personal TIPS, and see the block diagram. RUN the software calibration for diagnose, and troubleshooting.
