help.. my XZL cannot turn on.

my XZL's battery drained completely last night. i connected it to wall charger and went to sleep.

at 4am, i woke up and and saw the led still red and it wont turn on. i pulled out the charger and try to turn my phone on. only red led blink 3 times.

what is wrong with my XZL?.. i m soo malas to go to service center again. last time i send my XZL because of the black dot camera.
