When I plug my hdmi cable from my HP computer to my Vizio E470, no sound comes out of my tv. I hooked it up to my other hd tv, and sound comes out fine so i know my computer settings are correct. I have tried both hdmi ports on the tv and have tried all troubleshooting solutions, but nothing works.

Welcome to FixYa
Turn your computer off, and turn it around to view the rear of the unit. Find the cable that comes from the computer's monitor, and follow it to the back of the PC. The cable will be plugged into the output of the video card, which will be either a 15-pin VGA port or a 29-pin DVI port. If you are fortunate, there will be a second port directly next to it, of either the DVI or VGA variety. On the newest machines, you may even find a regular HDMI port on the card.
Choose the connection for video output. If your computer has an HDMI port, you can simply connect an HDMI cord of the correct length between the computer and the TV. Otherwise, you will need to make a few decisions. If your computer has only a single video output, and it will not be used solely with the television, you may want to invest in a new video card. Purchase one with either a DVI or an HDMI output, and install it in an available slot, according the instructions included with it. If you intend to use the VGA output on a single-output or dual-output card to drive the HDMI display, then a special device will be needed to convert between the formats, and the price of the converter is actually about the same price as an entry-level video card that will be easier to use with your TV. In that case, it may be a wise idea to upgrade the card in order to obtain a DVI or HDMI port. However, if your chosen output port is of the DVI variety, an inexpensive DVI to HDMI cable can be purchased to convert your computer's output into the proper HDMI input for your TV.
Connect the HDMI cable from your television to your computer. Install the correct adapter or converter for your computer, if necessary. Unless your computer has HDMI output, cords will also need to be connected from the sound card output to the HDMI video cable or adapter, because HDMI carries both video and audio signals.
Boot your PC, and configure the new display, by selecting "Control Panel" from the "Start" Menu. Then double-click the "Display" icon and click the "Settings" tab. The manual for your HDMI TV will list the screen resolutions it supports, along with the refresh rates. Configure the resolution in the "Settings" tab, and then click the "Advanced" button to set the refresh rate. If you are using the HDMI TV as the second monitor, you will also have to configure how it is used by Windows, according to the instructions pertaining to your video card. Most cards offer a "Clone" or "Mirror" mode, where both screens display the same content. Alternately, the "Extended Desktop" mode can be used, in which each monitor will operate independently.
Reboot your PC to apply the changes, if necessary, and prepare to relax on your couch and watch your movies on the big-screen HDMI TV.

depending on the age of your play station you may or may not have an hdmi output on the playstation. if youi do then its simple. one hdmi cable from the tv to the playstation and yoiur done. if not, you should have some round color coded plugs on the back of the tv and the same ones at the playstation. they should be just larger than a pencil eraser. these are called RCA plugs or phono plugs. the cables will have the opposite end with pin sticking out. you can go to google images and type rca plug to see a picture.
I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.
Likely standard VGA ... unless you have an HD card in your computer ... I got one for mine in order to play blu ray after I bought a blu ray drive for my computer. In that case I needed an HDMI cable. HDMI passes both the video and the audio, otherwise you need to connect also a stereo audio cable between your sound card output and the tv input, close to the computer VGA connection.
