Thanks Paul for the info, it seems baclight system failure in TV as no image visible without backlight and there are few possible causes for this failure, either backlight inverter section isn't working located on power supply board to provide high volts to backlights inside screen OR the backlight LEDs inside screen have gone bad and became unable to lit. It needs further troubleshooting with multimeter inside TV after removing back cover to check output volts of inverter section, if volts are available then backlight LEDs are bad and if volts are not available then pwoer supply board will be replaced which will help to resolve the issue.If LEDs inside screen found bad then it isn't good news and I'm really sorry about it because entire screen will need to be replaced which wouldn't be an economical repair and may cost approx new TV price of same size and at that point you would be better off with a new TV.I trust my input will help you out.
