Hello taasmost9, This problem indicates an issue with the inverter which operates the backlight. It appears that your inverter is malfunctioning. If you have a background in electronics, it is possible for you to repair this yourself if not you will do more damage then good so I would like to suggest that if you do not have a background in electronics that you have a qualified TV technician work on and repair this problem. If you do have a background in electronics you will need to measure the voltages at the inverter and determine that power id present at the inverter's input and at the output to the backlight. You will need a schematic and a multimeter for this task. After finding the component you have a choice of replacing the component or replacing the entire inverter module (this is up to you depending on the cost of each procedure). I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com
