    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.

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
              by cheeky2
              I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
              Obviously the same LVDS connector for the screen connection...

I then got online and found this great site! ....read many troubleshooting tips and this...

              Vizio D50u-D1 Dead: PSU or Main Board?
              by fharris1977
              Hi. Anyone who has experience with these vizio sets, which pin on this connector is the standby, the 5V pin? Trying to rule out the PSU before ordering a mainboard. I'm getting 0 Volts on all pins on this connector. Trying to jump the standby and PS ON pins to see if the PSU is functioning. Thanks in advance.
