I think i'm having a similar, if not the same problem as this post, but slightly different. I have not had my phone plugged in for an extended period of time like another posted thread that I found discusses. It was working fine until last night when the battery died, and now it won't turn on. When I plug it in, it flashes the LG logo and the buttons on and off but won't turn on. I've tried pressing the home button+down volume+power about 20 times and ways but to no avail. I brought it to a Sprint store and a guy took a look at it briefly and said he thought my OS was fried and he couldn't get it to turn on either. This is my last try before sending the phone back in to get it replaced, but i'd rather not do that so I don't have to go without a phone for 2 weeks.
