Need more info. How is your video source connected? Are you on the correct input? Is your video source on?

Hello,
Problem is in either power supply or the Y-Sustain board.
The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.
Often there are fuses on that board - one or more. Check those.
if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.
I hope this will help to solve the problem...
My first impulse is to tell you to go back to the store, admit you didn't understand what you bought and ask them to teach you.
My second impulse is to tell you to Go to Roku's site and read how to do it.
I have no third impulse.

You may have to change 'Source' to use the non-Roku source.

Check and replace the back-light inverter board.

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
