Hi Mike,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

You speak about the TV, but nothing about what it's connected to that is causing the resolution to be lower than you wish. If you are on any type of computer, you need to go into the video set up area and see what you can do to increase the display size. It's probably not the TV, it's more than likly the source.
Jack
Check Connections:
Ensure that all cables connecting your TV to external devices (such as your cable box or gaming console) are securely plugged in. Loose connections can cause display anomalies.
Test Different Devices or Apps:
Try using other devices or apps with your TV to see if the issue persists. If the TV's menu looks fine but a specific device is causing trouble, that device might be the culprit.
Adjust Picture Settings:
Navigate to the picture settings by pressing the 'Menu' button on your remote.
Experiment with different picture modes. Sometimes a minor adjustment can resolve display problems.
Soft Power Cycle:
Unplug your TV from the power source.
Press and hold the power button on the TV for about 3-5 seconds (this helps drain any residual power).
Plug the TV back in and turn it on. Some TVs also have a 'Soft Power Cycle' option in their settings menu, so check there too.
As you have tried a reset, that takes us to the options of contacting Vizio support and/or your warranty.
The power supply/subwoofer for the VIZIO CA-27 series all-in-one PCs is identified by the part number 715G6960-P02-001-002S or ADTVE1825AC71. The power supply connects to the motherboard via a proprietary dual jack Audio/Power cable. I couldn't find specific voltage details for the subwoofer/power supply in the available resources. For precise information, I recommend checking the user manual or contacting VIZIO customer support directly.
