@rburke26 if your screen does something in spite of the new power board which includes the backlight circuitry [https://www.youtube.com/watch?v=QCLZY8hMMfg|like this] there will be an error with the LED backlight strips themselves. These are replaceable but it is not easy since you will have to dismantle the panel. Post your panel number, not the TV's model number so we can try to find the right strips for you. The numbers are usually on a label fixed to the panel.
