Sharp Roku tv won't start

I have a 58 inch Sharp roku tv and all of a sudden when I tried to turn it on, it would not start up. There's a  red blinking light at the bottom right corner and sometimes it's a solid red light. I've tried every troubleshooting options and I have no luck getting it started as I'm slowly preparing myself to purchase a new tv that I can't afford right now. I need some help with this issue.
