Galaxy S5 - No display
After 4 months (1 month past warranty) my Galaxy S5 was working fine and then after a power down, the display will not light up. I can see the back an escape buttons lighting up along with the blue LED at the top. However, it won't turn on. I've tried holding HOME and POWER, as well as HOME/POWER/VOLUME UP to no avail. When I contacted customer service I was told it was out of warranty and probably had a bad battery. I bought a new battery. Same issue. Can anyone help?
