[Q] Phone will not turn on :( topic

I have an LG L9. So last night my phone died. After about 2 hours i plugged it up and nothing happened. Left it plugged in over night, and nothing happened. When i hold the power button for about 5 secs or so, the home button LED flashes but it won't turn on. My phone is not rooted or anything. Hope someone can help! :(:(:(:(:(
