Vizio E461-A1 no picture or sound

[ntehicks]

I am looking at a VIZIO Razor 46" LED LCD tv that is only 1.5 years old. this tv was purchased at Costco but the customer was told that the TV only has a 90 day warranty. I have pictures and tests.
U701 5.2 3.2 0
U702 3.2 1.2 0
U703 5.1 3.2 0
U102 5.1 3.2 0

power to main board I have all correct voltages
11.8
24.2
5.1
not sure where to look next.
so the tv turns on and the led lights up white but no picture or sound. and no backlight.

Re: Vizio E461-A1 no picture or sound

Does anyone know where I can get a service or training manual on this new of a tv. I have tested all of the voltage regulators but not sure if any of them are wrong. I tested the main rectifier when the tv was plugged in but off. and it is 168 vdc. when I push the power button that changes to 123vdc. once the tv is on the power led lights up. but the tv at this point won't turn off. the led stays lit no matter using the remote or the button on the tv to turn it off. when I unplug the tv and then let is sit and then plug it in the power light goes on and then slowly goes out.

Vizio SMs are like hens teeth. Here is a guide to VRs

Whilst all a little low 0.05 to 0.1 they look as if they will be ok.
Chances are it is the eeprom many cases of that being the problem on unresponsive vizios.
There is even an after market for them which is an indication of how many are bad.

Re: Vizio E461-A1 no picture or sound

is there a way to re flash the eprom while in the TV or will I need to get a new one and install it?

Hi ntechicks, have you solved the problem? I got the exactly same problem with my Vizio E461.

I was looking at this for a friend. and she found out that the tv was still in warranty. The tech came to her house and replaced what she told me was a large board. I wish I would have gotten more info on what board. but once he replaced that board the tv worked.

prob. was the mainboard.

It's a good chance its the U409 eeprom (flash) It's available on S.J. for $15.00.
Being that it was under warranty, vizio would have replaced the main board not have a tech try and reflash the chip, it's not worth it.

Yes, It would not be of much use if it did'nt.

Has anyone solved this yet? I'm having the same problem.

Re: Vizio E461-A1 no picture or sound

I may have had the same problem. Are you trying to mount the TV to the wall?

I have had my model for 3 years. Yesterday I moved the TV to another room to mount on a wall. I installed a generic wall mount system that connected directly to the TV. I first hung the TV and it worked fine. I then removed the base and the "neck" that slides into the bottom of the TV. With the neck out the TV has no picture or sound. I put the neck back in and everything works fine. Vizio says that it should work fine without the next. It would be nice to know if this approach solves the problem for someone else.

Re: Vizio E461-A1 no picture or sound

I am working on this same model set for a friend and it is completely dead. Power supply voltages check out ok, however when I push the power button on either the set or the remote absolutely nothing happens. I suspect it's also the EEPROM. I located it on the main board, but worried about trying to remove the old one and solder in the new. I have never had much luck soldering in surface mount components. I have the usual small pencil irons, solder wick, also a solder sucker. Since a used main board is quite expensive, (even on e bay), I am going to try my luck at replacing it. Any suggestions as to how to remove the old and replace it without ruining the board?

Re: Vizio E461-A1 no picture or sound

Well, I tried removing the EEPROM, I was very careful, but still the foil lifted up on 2 of the pins. Does anyone know of where I can get a rebult main board for this model Vizio E4461-A1 Board number is 715G5560-M01-000-004X

Hello,
Did anyone resolve this issue? Was it ultimately the main board? Or the EEPROM ? Sure could use the feedback. Please and thank you in advance 🙏🏽

Re: Vizio E461-A1 no picture or sound

Thread is 7 years old. I would assume it's main board, should start a new thread. Can you test voltages etc?
