SOURCE: LCD TV WONT POWER ON
A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.
First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.
If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

SOURCE: No Power to a Vizio VX32L
My best guess is to check for blown fuses or the power board when bad inside the TV.
If that doesn't work, looks like you'll have to pay a repair shop to find out what's really going on.
Sorry I can't help you further.

The Vizio VP322 is notorious for having bad capacitors on the power supply circuit board. They will probably be bulging and may have electrolyte leaking. I replaced four bad capacitors (with a different brand just in case) and fixed it. Total cost under $10. A lot cheaper and better than replacing the whole circuit board which may contain the same "faulty" capacitors from the factory.
