Need help troubleshooting TV

There could be several reasons why your Vizio TV goes black after being turned on, including a malfunctioning power supply, a damaged display panel, or a faulty backlight. Here are some steps you can take to troubleshoot the problem:

1. Check the power supply: Make sure that the TV is properly plugged in and that the power outlet is working. You may also want to try plugging the TV into a different outlet to see if that solves the problem.
2. Check the display panel: If the TV is getting power but there is no picture, the display panel may be damaged. Look for cracks or other signs of physical damage to the screen. If you find any damage, you may need to replace the display panel.
3. Check the backlight: The backlight is responsible for illuminating the screen, and if it is faulty, you may experience the symptoms you described. Look for any signs of damage to the backlight, such as flickering or uneven lighting. If the backlight is the problem, you may need to replace it.
4. Reset the TV: Sometimes resetting the TV to its default settings can solve the problem. To do this, unplug the TV from the power source, wait a few minutes, and then plug it back in.
5. Contact Vizio customer support: If none of these steps solve the problem, you may want to contact Vizio customer support for further assistance. They may be able to provide additional troubleshooting steps or help you arrange for repairs.
