SOURCE: only one of 3 hdmi ports work

If all 3 are side by side or even on same board I would suspect physical damage is the problem first--those HDMI sockets are not very sturdy and considering the way they are solder in not usually replaced by themselves.

We in our shop are not lazy but will usually just replace the board they are connected to if suspect the problem is not elsewhere in the set.

Lets face it--those were never meant for hard use-like plugging and unplugging a lot not to mention the poor quality of parts used in many cases.

Google the model with "parts" or visit the LG site---I have seen brand new out of the box sets with bad ones--the average person is much stronger than those sockets are. Makers of lap top computers learned this lesson early on and went to better made USB sockets for this precise reason.

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. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

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

I am connecting Yamaha DVD player to the Vizio M420 NV via HDMI. i have a picture but no sound. how do I gain audio when using HDMI?


HDMI has both Audio and Video (High Definition Multimedia Interface) and should carry both. However, I had this problem with a client just the other day and it turned out that the firmware on his TV needed to be up[graded. Different model TV, but I believe you may need to download the latest software/firmware update via your PC and put it on a flash drive and then flash the firmware on your TV to get it to work. Sorry I don't have the specifics; I was stumped and the Time-Warner guy ended up doing it. I hope this at least sends you in the right direction.

Our 42" Vizio will not display/play sounds when


Hello

One board takes in the HDMI as well as the other signals. Sometimes part of the board breaks and that is what sounds like has happend in your case. This is a fairly common problem and most people tend to just live with it. Others sell thier tv and a few find the number of thier board to see if one is available on ebay or shopjimmy. If you are comfortable with electronics the board is not hard to replace.

Im sorry your HDMI broke....

I hope this helps
