Unlock procedure to many popular brand TVs are given.
you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.
if you plug in the set, and the "Vizio" light isn't orange, most likely you have a faulty power supply board. Tests will need to be performed to be sure.
I would double check the capacitors on the power supply board. Make sure you don't have any that are bulged at the tops. Secondly, when you try and turn it on, does the orange light flash at all??
The main power supply , which is somewhat active even when the set is 'off,' is damaged.
With luck (a lot of it) it may have gotten enough spike to cause one of the (few) protective parts to fail, rather than serious damage having resulted.
Leave the set upplugged for at least hours (overnight is better) to allow certain components to discharge and remove the back panel from the set.
Look for obvious signs of burning/damage and possibley a fuse.
There is a part that limits peak voltages coming in from the AC line that often explodes when hit hard; if not in pieces, it is a disk-like device, mounted vertically with leads coming from the sides or bottom of the disk.
If you see only two wires sticking up and going nowhere, that is where the part once was and the damage is probably severe enough to make replacement of the supply necessary and this may not be the end of the repair.
