I have a LG Optimus S phone. It will not come on. I have 3 fully charged batties. I have a car, home, and usb charger that I tried all 3. All 3 work with my other lg phone so I know it is not them. When I plug it into a charger, It flashes the LG light and the 4 buttons at the bottom will flash on and off. I tried the reset where you hold the home, volume, power botton down. That did nothing. Can someone please help.
