Question about Sharp Televison & Video
I don't have a service manual for that set so I'm only able to help on a limited basis...Have you tried the flashlight test?...if the backlights are out then it could be a backlight driver board if it has one? or defective LEDs. See what you have for voltage going into the panel LED's

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?

The pattern of the blinking is a code. If the power light is blinking by itself once per second or thereabouts it could be loose connection to Inverters, reload firmware, Inverter Unit or LCD Panel.
