Find something soft to lay the television flat on its face. Remove the back of the unit. about 15 screws. locate the power supply board and unscrew it from its position and remove all connectors plugged into it. Mark the wires/connectors or take some pictures so when you get the new supply you can get it back together correctly.

SOURCE: the vizio light comes on as if the tv was turned on / the vizio light does not go dim to bright when the power switchis applied / tried changing power supply board / no change

frankly having it posted as a Sony does not help. Aside from changing a board you did not need to change what other simple steps have you taken? Vizio model number?

Some of the simple things (if you can see Vizio logo and it stays set is on) does it work via a DVD player etc, does it have audio etc.

It is here up to each expert to choose if they want to answer a question or not, with wrong model etc many may have just passed on your question.

If you get the Vizio logo and or OSD let us know that, the more clues the better.

My reaction would not be power supply but maybe just maybe a main board.

I would of course try other signal sources first, remove a cable or sat box and the set from power to see if things change or not.

Up to you how you word the question and what information you provide but up to us to decide if we want to try to help or not.

I personally answer over 400 questions a week so want to help if there is enough info for me do at least try to do so.

It says here zero views of this question which is why I took another look at it.

Vizio tv E470VL. Replaced power board and no change. Front vizio light will glow at bottom but tv will not come on. Please help.

Power board isn't the issue. Its the digital board and/or bad panel. As much as I love to repair things, Vizio is one company who isnt worth it. I have seen 14month old TVs with bad panels. The E470VL is a known problem TV. The panel is probably shorted and its keeping the digital board in protection which is keeping the power supply from starting. Its really frustrating. I wish Vizio would stop making such sub-par equipment.

My Vizio Tv will not come on with the Tv bottom or by using the remote.

Check the power supply voltages, could be the main or power board, you will need to see if you have PSON voltage or PON, depending what its labeled on the power supply board legion. If you see a change there then its the power board

check out the power supply board! Look for popped capacitors. They either leak or swell up. They are the can shaped things on the board with the plastic coverings on can usually see a swollen cap sticking up over its covering as a telltale sign.

Good luck and be careful

No Sound, No Picture

I had the same issue on my Vizio and fortunately it was still covered by the Costco extended warranty from where I purchased my tv. The service tech came out yesterday with a power supply and main board which is what I understand is usually the issue with your and my symptoms. He replaced both boards although he felt the issue was in the main board 3647-0072-0150 and not the power supply. Tv is working just fine now and actually may be even a little clearer after the board switch. I understand you can purchase the boards and from what I've seen the tech do, it is no more difficult to replace than if you were building a computer if you are comfortable with that. The most time consuming part of the repair was removing and replacing the screws.
