    you can test voltage regulators on them as vizio can suffer issues with them also not sure if it could be a bad/corupt eeprom/spi flash ic

      Can you expound on the bad/corrupt eeprom/spi flash ic? Is this something on the power board or the main board.
      I have replacement boards for all 3 (main, power and LED driver) and no matter which power board I use I still get 0 for On/Off and .1 for Dim.

        Vizio D50u-D1 Dead Set No Standby
        by fharris1977
        Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

        vizio e650i-a2 (LWJAOZBP Serial) led backlight flashes then turns off, has video (via flashlight) and audio.

        72 led total on 12 strips, 6 led per strip wired in three groups of 24 (led driver board has three anode and three cathode pins)

        Vizio E701i-A3 Vizio logo flashing then turns off
        by Super360
        Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

        Vizio, E60u-D3, no standby light, no ps_on
        by p-top
        Have vizio E60u-D3. No standby light. Have searched and read all D??u-D3 posts. posts with same symtoms fixed by new power supply, one guy needed back lights also.
        main boards are kinda spendy and, out of stock alot of places. i would like to fix my board.

        PS voltages

        1 VSNS -2mV
        2-5 LED-OUT -2mV
        6-10 GND -2mV
        11 +16VS 16.29V
        12 AC-DET 3.929V
        13PS-ON -3mV

        Vizio E550i-A0 no power, no standby light
        by x_orange90_x
        I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me...
