Hello. I am trying to repair a Vizio E32-C1 dead set. When I plug the set up, I don't get the standby led. So I assumed it was the power supply. Tested it and the standby voltage wasn't present. So I've ordered numerous power supplies (715G6934-P01-001-002H) and all of them have no standby voltage present, even with just the power supply plugged in. Am I getting bad boards or does this particular set generates its standby voltage from a different source. Anyone familiar with this particular set and power supply, your help would be greatly appreciated. Thanks in advance.

Re: Vizio E32-C1 No Standy Voltage
Lets see the pictures of your boards.

is this your board?
So the connector of the power supply that goes to the moan board shows 0V on all the pins?Never stop learning

Re: Vizio E32-C1 No Standy Voltage
Hi. Yeah this is the board I have. I don't get any voltage for Ps On or any of the 5V lines. I do get all of the 12 volts for the 12 volt lines though.Comment

Re: Vizio E32-C1 No Standy Voltage
I have ordered over 4 boards and all of them are reading 0 volts on all the 5V lines.Comment

Re: Vizio E32-C1 No Standy Voltage
Well, that power supply is running.
Show us the whole back side of the TV so we can see all the boards.
This power supply only has 12V output, the 5V section is not used so the parts for the 5V power supply section is not stuffed with parts as you can see.
PS-ON is not used either.Attached FilesLast edited by budm; 09-20-2019, 10:15 AM.Never stop learning

Re: Vizio E32-C1 No Standy Voltage
If you look at the bottom of the board, you will see the +5v is not used, If you have 12v the power supply is workingComment

Re: Vizio E32-C1 No Standy Voltage
OK. With all Bds connected and screwed down in place, when you plug in the TV to the ac you do not see a stand-by led on. Now when you press the Power button on the TV or the Remote, the TV does not turn ON and the stand-by led remains OFF?Comment

Re: Vizio E32-C1 No Standy Voltage
I have checked plugged the boards up and connected them and I still don't get a standby Led. Could the main board or led strips cause no standby led?Comment

Re: Vizio E32-C1 No Standy Voltage
Did you press the Power button on the Remote or the TV?Comment

Re: Vizio E32-C1 No Standy Voltage
I pressed the power button on the TV. I have to find the remote to see. I was thinking maybe the power switch was bad alsoComment

Re: Vizio E32-C1 No Standy Voltage
Sounds dumb but did you check your power cord or try another one?Comment

Re: Vizio E32-C1 No Standy Voltage
Lol. Yeah I checked it after the first 2 boards didn't work. I'll check that power switch and see if it's getting any power.Comment

Re: Vizio E32-C1 No Standy Voltage
I can't imagine all your boards having the same problem but on some of these e model vizios the rectifier diode/s short out, causing a dead board. I'll leave this BUT I got my threads mixed up, was thinking you had a completely dead board so this doesn't apply here.Last edited by nomoresonys; 09-20-2019, 12:11 PM.Comment

Re: Vizio E32-C1 No Standy Voltage
Power board is sending the 12V to run the main board, since you do not even getting the Standby LED to come on so you have something going with your main board but I cannot tell you where to check on your main board since we do not have the pictures of the boards.Never stop learning

Re: Vizio E32-C1 No Standy Voltage
Is your mainboard on this page, go by the sticker numbers as directed: https://www.shopjimmy.com/catalogsea...sult/?q=E32-C1Comment

Re: Vizio E32-C1 No Standy Voltage
The correct way to test the powerboard voltages is in #3 in my signature bellow, try to do it just as directed, looks like the 5v isn't connected, so don't worry about that one.Comment

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 ?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.

I have no standby indicator light and no light on the optical port. I checked the standby voltage on the two mosfets in the top left and they both read 30mV. I checked the fuse and it has continuity. I also checked the voltage on the two large 450v caps they both read 153v. All of these voltages are the same with and without the main board connected as well as with backlights connected/disconnected.
Nothing looks obvious like a burned ceramic disc cap or bulged electrolytic. No burned resistors, diodes, or anything like that.... -
Hi All, I have a vizio e550i-b2e that has no standby voltage. I am hoping some one can help. I am getting 10-14volts bouncing at pin 5 of ic901 (Vcc). According to the data sheet for that ic I need atleast 16v for it to turn on. I did a thermal scan and the only thing that glowed was d901.... -
Hello,
I have a problem with this TV, the standby voltage is not present. I have checked the components around the IC fsq510's area and they seem to work, also replaced this IC but the problem persists.
These are the voltages in some pins of IC fsq510:
Vcc=18v
D=320v
Vstr=154v
Unfortunately, I couldn't find the schematic
What else could I check?
Is it possible to provide standby voltage from an external source to allow the TV to turn on?
Thank you​...
