I have a LG Optimus V that suddenly died! I was listening to streaming music with headphones on, with it plugged into charger as I slept. When I awoke, it was off and will not turn on again..Tried the 5 second plug/uplug 5 X that LG suggested..Virgin Mobile said their screens showed it plugged in and charging...but I cannot get it to come on. PLEASE, any suggestions would be helpful! THANKS SO MUCH!
