They are not usually available except by authorized service centers as no parts are really sold and only circuit boards are available in most cases.

How do I fix my Vizio TV model E421VA? Details are below. It has a black screen and no audio.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Visio e421va have stdby and power on light


This is going to be one of several problems. Very first think to check is fuses and capacitors. Then I would start with the power board. Check your voltages on the in and output side. If they are all good I would go to the logic board. That is the small board and pretty inexpensive. From there you have to go to the TConn, but I don't think that is it. The next step is the X and Y board. It is most likely going to be the Xboard. If you are not getting audio or video then you can unplug the logic board where it connects to the main board. If you get the sound upon turning it on with it unplugged then your logic board is one of the things that went bad. Most cases you will have to upgrade the firmware with your new boards.

Getting no audio from speakers on a Vizio E421VA LCD HDTV, any ideas?


Do headphones work?
my guess is either the headphone socket or associated wiring/soldering is faulty or there is a faulty connector within (connector associated with the audio)

hi,

It can be difficult to get things right on the first try. With that truism in mind, Vizio Incorporated includes USB ports on their televisions that you can use to load firmware updates onto the television. Vizio has released firmware updates only for certain television models, and the instructions for installing firmware updates vary slightly by model. To upgrade your television's firmware, you need to download and copy firmware drivers to a USB flash drive and then read and follow Vizio's specific installation instructions for your model.

1. Connect the USB flash drive to your computer


2. Click the "Start" button, and click the "My Computer" icon.
3. Right-click the flash drive, and click "Format" in the menu


4. Select "FAT32" in the drop-down menu, and click the "OK" button. Windows will format your USB flash drive with the FAT32 file system.


5. Open your Web browser, and navigate to the Vizio support Web site at www.vizio.com/support.

6. Click the "Select Your Product" drop-down menu, and select your model of Vizio television from the list. A new page will open that displays available downloads for your television


7. Click the "Firmware Update" link, and save the firmware update file to your computer.

8. Click the "Firmware Instructions" link, and read the instructions specific to your Vizio television model.

9. Right-click the file that you downloaded, click "Rename," and then rename the file to the exact name that is specified in the firmware instructions 10. Right-click the file, and click "Send to" > "E: USB Drive" or whichever drive letter corresponds to your flash drive. The firmware update file is copied to your USB drive 11. Right-click the "Safely Remove Hardware" icon on the right side of the Windows task bar, and eject the device from your computer

12. Disconnect the USB drive, and plug it in to your Vizio TV's USB port.


13. Follow the steps in the firmware instructions to install the firmware update to your television.



Only you can find is the problem with firmware by udating the frimware of your tv. ok
