Vizio e421vo

11-14-2012, 07:41 PM

Hello, I am new to this forum so please bare with me.
I am also new to electronics.
I have a E421VO Vizio tv that is not working.
I already changed the power supply and the main board with no luck.
all it has is the orange light but nothing happens when i push the on button on the tv or the remote.
I checked with the multimeter on the power supply and I get 5v on the stanby mode.

Please help.

Thank You.

Re: Vizio e421vo

Does the part number on the main board match the one you replaced?

Re: Vizio e421vo

yes, everything matched. i found a thread here that says to replace the eeprom.
I found eeprom but now I wonder what solder gun to use and what kind of solder if there are different kinds.
do you know?

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.

Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply

by sam_sam_sam

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

Modification to a ZD-987 desoldering/soldering station using a external switching power supply

by sam_sam_sam

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

Hi, Can we use SMPS Bench Power Supply for Laptop troubleshooting?

by shamsudeen

Hi all, I just need to know that, can i use SMPS type power supply to test and short circuit detection on a laptop motherboard?
I saw 95% of repair guys are using only Linear bench power supply. linear bench power supply is pricy, thats why i planned to get one SMPS supply.

i know that in linear power supply the noise will be very low comparing to SMPS supply....
