    Vizio VP322 VS VA Readings

    TV shows power, but won't cycle up. When power button is pushed, relay clicks and then shuts off. I know it's a common problem with this model to have failed capacitors, and it looks like they have all been swapped already.

    When the Y Main is unplugged VS, VA, and 5 volt all read good. When the Y Main is plugged in VS= 17...VA jumps to 160 ...5V = 5V. All jump for like 5 seconds then drop. VA is listed at 60, so it's very high with the Y Main plugged in.

    Would the power board still have an issue if it's throwing out good voltages on its own? Or is this indicative of a Y Main issue? Couldn't find any short MOSFETs on the Y Main either.

    If anybody ever comes across this, a new power board fixed it.

      That's strange the power board must have found supplying the y side was just too much for it.
