hisense 55K20DG no backlight

Hey guys. So no backlight at all. not even a flash. I'm getting 330 volts at the connector for the back light. Would mean I have a problem with the strips themselves correct?

They drive those LED to the max and with poor heat management.
Once you get it fixed you should then turn down the backlights level to as low as you can.
Yours is not as bad as the one in LG TV's.
