Should an MHL adapter just work?

My Vizio 47inch 3D tv just won't recognize my Galaxy S4. It says connected but my HDMI input says "No signal"
I am using the 5 to 11 pin adapter already and other TVs in my house recognize my phone no problem. My Vizio TV just doesn't.
I tried different methods, different HDMI cables and Inputs and still nothing.
The weird thing is that it worked just once when playing XBMC. Then I unplugged it and plugged it again it just didn't work anymore.
I am starting to believe this is a problem with the Vizio TV itself.
 
Re: Should an Samsung HDMI - MHL cable

Yes I was wondering if that Samsung HDMI MHL cable will work for my Samsung S6 active
 
I was forced to purchase a new cellphone to continue using T-Mobile/MetroPCS signal.
Now I need to find a 5 pin MHL for my LG STYLO 3....

I just purchased from eBay (Got a refund) and Walmart, DP AUDIO VIDEO MHL HDTV ADAPTER for Samsung, HTC and more received today.

IT CURRENTLY WORKS FOR SAMSUNG NOTE 3. THE CONNECTION HOLDS BETTER THAN THE ROCKETFISH FROM BESTBUY!!!

Its a 5 pin...Still No Picture or Charge!!! :(

Any recommendations,

Preferably any LG Cellphone Users...

Thank you
