Facing TV Problems? Ask a TV Technician.
Hello, Please let me know if the backlights to the screen are ON or OFF when the TV is turned on.
Okay, this means the backlights to the screen aren't on. We need to test this for certain. Dim the lights in the room or shut them off. Shine a flashlight directly at the screen at a 45 degree angle and look very closely. Check for any shadowy images moving behind the screen. The reason I'm asking this is that it would appear the power supply/inverter board is at fault. The T-Con does not control the screen lighting in any way.
Okay if there's no backlights at all then you need to replace your power supply/led board which is at the link below for $65- and will fix this problem:
This board powers the backlights in the screen and since they're out, this is the part that causes this problem.
If you need further assistance let me know. Please do not forget to click the 5 STAR RATING, at the top of the page for my efforts. It is my livelihood and you can follow up at any time if needed.
Do you need further assistance with this?
The LED inverter/power board has multiple outputs on it- and the TV can stay running even when one has failed. So you have the 5, and 12 volt outputs, but don't have the LED output voltage- which is why your LED's are not lighting up.
Let me know if there's anything else you need.

Hi, Was there something else you needed?
That's bad news. This means your LED lighting in your screen has failed- which means you need a new screen. These aren't available for purchase anywhere, and when found cost about 80% of what the TV cost when new. I'm sorry for the bad news on this one.
