@akl27873 if it turns on and off consecutively and you can verify that it turns off with the power LED (Power LED turns on and off the same way), then it is the power board. If it is just your picture that turns on and off (power LED stays on the whole time) it is your backlights that have failed. That is a common issue with Hisense TV's.
