My phone wont turn on?!?

So I was using my phone ( on snapchat) when it died ( it was flat) so I plugged it in and left it for 5 minutes, when I came back to turn it on It would vibrate and show the Samsung logo but then turn off again and wont go any further than that... I have tried to factory hard reset it but it just kept vibrating and showing the logo, I did sit my phone in a little bit of juice earlier, but I don't think it was enough to get inside the phone it was working fine afterwards until now... please help me!!! this is my second phone this year and I cant afford a new one/ to send it to the shop
