My element tv has no picture. (it can be seen with flashlight test) will a power supply repair kit fix this issue?

If your Vizio TV has sound but no picture, and you have already done the flashlight test, it may indicate that your TV's backlight or power supply is malfunctioning. Here are some steps you can follow to troubleshoot the issue:

1. Check the cables: Make sure that all cables are properly connected between the TV and any devices you are using, such as a cable box or DVD player.
2. Check the input source: Ensure that the TV is set to the correct input source that the device is connected to. You can cycle through the input sources using the input button on your TV remote.
3. Power cycle the TV: Turn off your TV and unplug it from the power outlet for at least 1 minute, then plug it back in and turn it on again. This can sometimes resolve issues related to the TV's power supply.
4. Reset the TV: Try resetting the TV to its default settings. You can find this option in the TV's menu settings.
5. Contact support: If none of the above steps resolve the issue, it may indicate a hardware problem with the TV's backlight or power supply. In this case, you should contact Vizio support or a qualified technician for further assistance.

The next step would be to check the inverter board. This board is responsible for supplying the power to the backlight. If the inverter board is defective, it will need to be replaced. If the inverter board is not the issue, then the issue may be with the mainboard.

Hi Terry,

If you can see the faint picture in flash light means the power supply and the main board is working. The real culprit is the backlight. Even one bad LED in the backlight will switch off the whole array. To repair this fault the panel has to be opened and the defective LED or LEDs are to be replaced.

This is a complicated, delicate and risky job and must be attempted by an expert only. You may end up damaging the screen permanently if you have not done it before and try to DIY.

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

I would first try the good ole flashlight test. Turn off the lights in the room, turn on the TV and shine a bright flashlight on the screen. Do you see a faint picture?? I'm willing to bet you will, this is most likely a backlight failure. I'm willing to bet either the inverter or the 24Vdc power supply circuit has a fault. Do you have any electronics repair skills??
