Query: Didn't work

I was excited to receive this straightener as my old one (FHI) was 4 years old, and I wanted one that I could control the temperature.It arrived quickly to my delight, and the next morning I plugged it in, and the screen began to flash. I pulled out the instructions, and it stated that was normal, as it flashed as it was heating up. 5 minutes later, it was cold, and still flashing. I tried a different outlet and still the same outcome.I didn't even want to exchange because of that.
