Vizio Razor 22" LED No picture, won't power off

[dpoolepcagc]

Ok I been a lurker for a week now. I been looking to see if I could find a fix without bothering anyone. I haven't been able to find exactly what I'm looking for. SO here I am looking for some help.

I have a Vizio 22" razor LED. (about 15months old) It all of a sudden has no screen. The white power indicator light will come on but I get no screen. Once I turn it on the remote and the controls on the side of the tv don't work. The only option is to turn it off by unplugging it. After being unplugged for a good portion of the day. My wife plugged it in and it worked. She watched it briefly and turned it back off. Now its back to no screen and can't turn off.
I took the back panel off and to me I see no bulged caps or leaks. I will be the first to admit I have no electronics background. I crawl through 30" pipes at Nuclear power plants inspecting for corrosion for a living. So I believe I have a good eye for detail but electronics is not my specialty nor will I pretend it is. I do have an ohm meter but don't know much about using one. I am ok with ordering a replacement board. I just need to know if its the main board or the power supply board because the set isn't worth replacing both boards.

Thanks in advance.

"The white power indicator light will come on but I get no screen. Once I turn it on the remote and the controls on the side of the tv don't work"
Right now the standby power supply may be working but the main board is not working properly due to standby voltage may be not quite right or the main board may have bad voltage regulators, which is very common failure in VIZIO.
You need to upload the pictures of your boards so we know what we are dealing with.
Take good close up pictures of the connectors so we can read the labels.

I was not sure which connectors close up were needed. So if I missed them or need something better I will try.
Thanks

All boards: you have more tahn one boards in your TV.
Example: The power supply board white connector, CN902 white connector, the wires are in the way, cannot read the labels.

I can see the pin labeled as ON/OFF, DIM, 16v, 12v 5.2V?????? too much flash. If you looked at the pictures you took, try to read those labels using the the pictures.
Take the voltage readings on that CN902, PIN 1 has white dot next to it. Check it with the TV off, and TV on.

Re: Vizio Razor 22" LED No picture, won't power off

Ok the pin is labeled as followed 1, on/off, dim, gnd, gnd,gnd,+16v, +16v, +5.2v, +5.2v, 13
with set off I get 0.226
with set on I get 0.232
However the display actually lit up this time. So I will have to retake reading once the display goes out correct?
if I leave it unplugged for a few days and plug it back in the display will come back on but not for long. So once it goes out I will retake the volts

Ok the screen went out. I unplugged it and plugged it back in and all I get is the white power light. The volt reading at the 1 pin was .715

You should have the 5.2VDC the minute you plug the TV into the outlet. What is the full model number of this Vizio?

Re: Vizio Razor 22" LED No picture, won't power off

Ok,
On the box under model number it says Vizio E220VA

I took a volt reading of the connector where the power is coming into the board from the wall and I got 7.2V I checked the #1pin on the connector you asked me to check (Yellow wire) and got .171V The screen was on this time, not sure if that matters or not for that reading
