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:
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.
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.
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.
Reset the TV: Try resetting the TV to its default settings. You can find this option in the TV's menu settings.
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.
My 47" LCD Smart T.V. was working fine last night. I got up this morning and I have sound but no picture. The VIZIO icon lights up as usual but I get no picture, only sound. From the time I turned it on, nothing appeared on the screen. I have already tried unplugging it for a while and still nothing.
The pop has been generated by the explosion (literally) of an capacitor from the power board of the tv. When that happened the power source has been shorted and, if you're lucky, it went in protected mode. Fixing that is a relatively simple job - all you need is a soldering iron and a basic experience in using it. Follow this

replace the sustainer boards should correct this problem. New sustainer boards may cause red and green pixilation. If this happen, replace control board and TV is as good as new.
