The Television must support Progressive Scan or else it wont work. I just bought a cable myslef and found this out the hard way.

SOURCE: No signal when connecting PC to TV

This happens to almost every laptop I know. Here are several solutions:
1. You need to manually enable video on tv by pressing two buttons on your laptop keyboard. The first is "Fn" (at the left bottom). The second depends on your laptop manufacturer. Look at the function keys. F1....F12 for the LCD/CRT or the corresponding sign. Press and hold Fn and press second button. Sometimes you need to press second button several times. This means you need to cycle through all available options to enable Laptop's screen and TV screen at the same time (clone).
2. Intel Extreme Graphics video cards sometimes doesn't support a procedure described above. You need to find intel video card options manager running at the sys-tray (right bottom of your screen near the clock). Right click on it. Select Graphic Options -> Output to -> Laptop + ... clone (or something similar)
Note that not all video cards are capable of showing the movie on media player at the same time. You need to choose Laptop or TV

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.

If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.

SOURCE: Pioneer vsx-819H: MCACC setup won't display on tv

Its because the pioneer does not display menu options through hdmi. You have to hook up basic yellow composite to monitor out.

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
