Vizio VO320E no power

[arkangel1975]

Hi all,

I have sifted through the forums, but I can not find anything addressing my question exactly. While watching the tv (never had any problems before at all) it just suddenly cut out. It will not power back on and I do not even get the orange or white Vizio light. I checked the PSU board, the fuse is fine, all the caps do not show any sign of any kind of expansion at all (actually they look new).
I do not have any knowledge of how to check the voltage regulators, if someone can point me in the right direction that would be great. I have searched all the references to this model in the forum but none seemed to help.

Thanks!

You can start with this:

The power supply connectors have labels for each pin to tell you what those are pins are, that is where you wan to test the DCV.

I did, all the 5 and 12 volt lines did not show anything, neither did the PSU_ON line?

So NONE of the pins of the connector has ANY Voltages? If that is the case then you need new power supply board.

Re: Vizio VO320E no power

Yes, none of the are showing any voltage. I was afraid of that, is there any component that I should check (other than the fuse) that is commonly the problem?

At this point I am trying to decide if it is worth fixing due to its age.

Well, next step will be in-depth component level troubleshooting start at the standby power supply section first.
Used 32" TV is not worth that much.

Re: Vizio VO320E no power

where would the standby section be located?

The pictures in those link you are referring to are not clear enough for me.
