    I'd have to say I'm guilty of swapping a component out on a hunch but it usually would either have the same symptoms of the previous failure or simply be a matter of having the part in front of me so, what the heck, change it. For me personally, being a field systems tech (vs. a bench tech) for so long, I'm not where I'd like to be with component troubleshooting without schematics. If I have a schematic, I'm ok - just ok, lol.
    I've worked in both worlds. When I worked on TVs schematics were usually available, and the circuits were functionally very similar. I moved to electronics production where schematics, parts lists, and parts were readily available, but the type of failure was radically different. Locating solder shorts is an art in itself. TVs have progressed to the point where it can take hours to analyze a circuit. Even if schematics are available, tracing a signal line across three pages of a PDF is more of an exercise in frustration than instructive. And schematics for many subassemblies are unavailable.

    For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

    Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

        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...

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

        panel: au optronics T650HVN05.4
        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 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.
