My VIZIO C50-m1 is not showing any picture but I can hear sound

My VIZIO tv all of a sudden didn’t want to show picture it was working fine 10 minutes before and now all of a sudden it doesn’t want to show picture when I turn it on. I can hear my ps4 in the background and the power light comes on but after a while the power light start blinking and the sound turns off does anyone know what board I need to replace
