    VIZIO E320FI-B2 dead no standby voltage

    It's been a while since I've looked for help this time I have a little VIZIO E320FI-B2 power supply was dead ordered a replacement from Ebay and this one is also dead I will include pics of both boards in figuring out how to test the 5 volt side for standby the replacement power supply is not as dead as the original one I have voltages at the capacitors waiting to be turned on obviously I've checked fuses but I don't have 5v on pin 1 and 2 and I think I'm supposed to and that's with and without the mainboard plugged in

              can we have a clear picture of the whole main board and another one of the location?

                  How many Ohms does it show?
                  We need pictures of the main board and this 'F2'

                      Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                      by tvguy12012012120
                      This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                      Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                      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...

                      Vizio M65 C-1 power supply dead - NO standby voltage
                      by funkmunk3y
                      Hello!
                      I was given this Vizio because it would freeze up after a few minutes of operation. There were no obvious burns marks or failures. When I was checking the power supply - I slipped & shorted it (tiny crackle & spark) at one of the 12 volt pins - now the entire board is dead & has NO standby voltage @ the connector to the main board.

                      The fuse at the power input is reading good - the main caps are reading in the 160's & all the diodes read good except one (D9103 - pictured) - but it only reads bad in circuit - I pulled it & it tests o.k.
                      ...

                      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.

                      un60j620dafxza - Samsung No Display Problem
                      by stylishconsultant
                      Hi All,

                      Need help.

                      I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

                      So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
                      problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
                      might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....
