cRIO not turning on!!!

[etphonehome]

is your cRIO electrically isolated from the chassis? if no, is/has anything elsewhere in your electrical system shorted through the chassis? if yes, you probably blew your cRIO. if this happened, you've got 2 options: send it back to National Instruments, or void your warranty, take off the back, and check and see if the fuse (located between the serial port and slot 1 of the modular breakouts if i remember correctly) is blown. If the fuse blew, you can solder another on top and it may be good as new. im not gonna endorse the voiding the warranty option, but it is an option if you think you fried it and dont want to wait for national instruments to fix the cRIO for you.

if you're pretty sure you didn't blow your cRIO, i don't know what could be going on.
