In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Great question - I would check that out with Vizio because I have read accounts of parts incompatibility in cases such as the one you cited. And you do not want to get a board that does not work because usually there is no return on electric parts.

UNPOWERED INPUT DEVICE

Check to make sure the device you're trying to use with your TV is plugged in and turned on. While it may seem like a silly oversight, it is possible that you switched on your TV and didn't actually turn on your DVD player, gaming console or whatever device you're trying to enjoy. If you tried to use a remote to turn on the device, check that the batteries still have a charge and turn on the device using its built-in power button.
TIP The problem may be your input device itself. Check your TV with other devices and see if it displays them properly. If it does, contact customer support for your device for more detailed troubleshooting instructions

WRONG INPUT CHANNEL

Make sure that your TV is on the right input channel for the device you're trying to use. When your TV isn't switched to the right channel, no visual or audio input from the device will display on your screen or through your speakers. Turn on the input device and press the Input button on your remote to cycle through your input channels until you see the device's display on your screen.

AV CONNECTION PROBLEMS

If you're on the right input channel and your device is turned on, there may be a problem with the physical connection between the device and your TV. Make sure that all cable connections are secure, and also that all cables are connected to the In ports on your TV and the Out ports on your input device. If you're using a connection that has color-coded plugs, make sure the connectors are inserted into their appropriate color-coded ports.
If you're using an HDMI connection, make sure that the cable you're using is compliant with High-bandwidth Digital Content Protection, especially if your TV and input device are both HDCP-enabled. HDCP is a copy protection system that prevents the copying of digital video and audio content as it travels over the connection. Systems connected with non-compliant cables won't display any video or audio conten

FROZEN TV

Periodically a TV may freeze up, showing that it's still turned on but not actually displaying any information from your input device or the TV's menu system. To fix a freeze, power cycling is the best solution. TEP 1 Turn off the TV by pressing and holding the Power button on the cabinet until the TV powers down.
STEP 2 Unplug the TV from the wall power outlet.
STEP 3 Press and hold the Power button on the cabinet for 30 seconds, and then release it.
STEP 4 Plug the TV back in and turn it back on using the Power button on the cabinet or your remote control.

HARDWARE OR SOFTWARE FAULT

If everything is correctly set up, powered on and on the right channel and you still aren't getting any picture or sound, there may be a hardware or software fault in your TV. The best way to check is to press the menu button on your TV or remote and see if the on-screen menu appears. If the menu doesn't appear, contact repair
