The Vizio VP322 HDTV10A TV is a 32-inch LCD TV that has a 30,000-to-1 contrast ratio and 60,000 hours of screen life. Unlike some TV's, the VP322 features a detachable power cable instead of a built-in power cable, which can be as problematic as it is convenient, as you can accidentally unplug it, giving the appearance of a power problem. More severe power problems can be the result of physical or electrical damage, faulty equipment or outlet issues.
AC Outlet
If the Vizio (vizio.com) VP322 HDTV10A TV is connected directly to an AC outlet, disconnect the power cable from the outlet. Plug the power cable associated with a device that you know works in to that outlet. If the device works, proceed to the other sections to troubleshoot other aspects of the TV; if the device doesn't work, try resetting the circuit breaker associated with that outlet to see if the breaker may have been tripped or turned off. If resetting the breaker doesn't work, the problem may be with the outlet. Remove the outlet from the wall and check to make sure all of the wires are appropriately connected. If the wires are properly connected, you may need a new outlet.
Power Strip
If your Vizio VP322 HDTV10A TV is connected to a power strip, disconnect some of the other devices connected to the power strip and reset the device. If the TV still won't turn on, try plugging the TV directly into the AC outlet. If the TV works, the power strip may be defective and should be replaced.
Power Cable
Check that the Vizio TV's power cable is firmly connected to the back of the TV. If the power cable is frayed or damaged, the cable may not function correctly and could be the source of the problem. Replacement three-prong power cables can be purchased from most stores that sell TVs and accessories and are also available from Vizio directly. As of October 2011, Vizio replacement power cables were available on Vizio's website for $10.
Power Supply
The worst-case scenario is that the TV's power supply no longer works. The power supply could be physically damaged, for example if the TV was dropped, faulty, or the TV could have been hit by a power surge as a result of an electrical event, such as a lightning strike. A replacement power supply for the Vizio VP322 HDTV10A TV isn't directly available from Vizio but can be purchased through third-party vendors online. Contact Vizio technical support to find out if your TV is still under warranty and whether or not what caused the damage is covered. You may be able to return the TV to Vizio and have the power supply replaced for free.
