Have you checked for a cracked circuit board. Very minor cracks in a circuit board may cause a break in the circuit when the boards are flexed slightly. Loose solder joints will also cause problems when boards are flexed or stressed when screwed tightly etc.

Agreed.

Hi, You will have to take the back off and look at the main power board. Make sure the plug is out when you do this. Look at the capacitors. If you are not teck savy get help. When cost of parts ar more than a new TV then go buy a new TV. Good luck.

Likely a failed power supply. Checking for certain failed components requires some technical knowledge.

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.

No model number so generic advice only. Google 'vizio (model) manual'. ..
