    [QUOTE=budm;580951]"It came right up to 5.09 v right away and then dissipated down to 1V " OK, that is not normal, the STANDBY 5.2V is an always on power supply that is running 24/7 hwne you have the TV plugged into the outlet. So it is either there is problem in the standby pwoer supply or the main board is load the standby power supply.
    You can try this quick test, unplug the TV from the outlet, then heat that section I marked with hair dryer for 2~3 minutes, then plug the TV in and monitor the 5.2VDC pin, then turn the TV and see if the 5.2V will stay on at 5.2VDC. When STBY power supply drops out, every thing will drop out with it.

    Hello Budm

    I have same model vizio tv, but my power supply is not the same shown in the picture.... my one is vizio 92424ABV.... 715G4069-P01-W30-003M

    the problem I have is that the tv does not present logo power and does not tunr on... when measuring voltages everything is present at power supply (24, 12 volts), but 5 volts terminal is about 2.6.... if i disconnect the main board the 5 volts terminal shows 5.1 and 24, 12 dissapear.... heating up the start up whe only see logo starting for a very short period and very dimm when connecting the set.... what could be wrong with this unit?

      Please start a new thread with make and model in the tread name and also upload good clear pictures of the whole backside of the TV and the power supply board so I can look at them and give you the test points to test.

        I have a vizio E470va power supply ADTV92424XBV There is no standy 5v. Which caps should I check? If I had a schematic, I could figure it out.

            It is. I will take pics tonight.
            I also wanted to ask if the adtv92424xbv and adtv92424abv
            are interchangeable?

              Shopjimmy does not show alternate P/N for this power supply.

                I have closer ones too.
                I did notice the burnt looking area on the bottom. It's a CAP.

                  I have closer ones too.
                  I did notice the burnt looking area on the bottom. It's a CAP.
                  So, I replaced the 1000Uf cap in the 5V supply and it's giving 5v. Also I get 24V come on when I jump 5v to the P On.
                  But the 5V drops out if I connect it to the TV. I checked and it still drops out if only the main board is connected.
                  Any Ideas now?

                    Vizio E65-F0 really dead
                    by Iain P
                    Hi everybody!

                    I've got a Vizio E65-F0 smart tv that is good and dead. It shows no signs of life when I press the power button on the back. The power LED in the lower right corner doesn't light, there is no backlight and no picture.

                    So I took the back off and started poking around figuring one or more of the caps had dried out. My esr meter says all the caps on the power supply board and the mainboard are less than 1 ohm.

                    I decided to check the voltages coming off the power supply they are as follows:

                    connector CN201
                    pin 1 (18vsb1)...

                    Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
                    by flibidy
                    I have here a Magnum IA.100 which belongs to my parents.



                    The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


                    Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


                    What Ive done........

                    Dead Vizio D40u-D1
                    by catnapped
                    Recently had my bedroom Vizio D40u-D1 apparently die while it wasn't being used. Noticed the power LED flashing, figuring maybe a software upgrade, but attempting to turn it on proved that wasn't the case. When powered on, the power LED will flash a bunch of times after about 2 minutes then turn off again. Definitely is no picture even with a flashlight on the screen. Had the opportunity to open it up over the weekend. Doesn't apper to be anything out of the ordinary visibly inside, nor any odd smells of escaped magic smoke. Readings from the connector in the corner of the power supply board...

                    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.
