Help us help you. The more complete the description of your problem is (what MBA you're using, what OS you're using -there's a lot of those, some history - was the machine dropped, crushed or wet?) the more assistance we can provide, and, the sooner we can provide it.
Try a Safe boot (shift). Try a R or D boot depending upon your OS, any difference?
If this answer is acceptable please remember to return and mark it.

i'm using mac air mid 2013 13" , using maverick o/s.
history : machines was wet. after blowed dry. plug in power no response.
what i have done :
replace logic board on my own , then encounter power on/off after power plugged in .
open up the back cover and plugged in power , seeing fan spinning and stop , spinning and stop then startup sound on and off.
now replace the i/o card -same thing happen again
now not sure what to do next ?
Yea - blowing air into it was the worst possible step to take. You have to look that logic board over really well and talk with your replacement logic board vendor. I suspect the problem might be a damaged blade drive or connector. POST (Power On Self Test) is starting, then something triggers a sudden shutdown.
