Hi All, I recently bought an MHL adapter for my Galaxy SIII, before I knew that Samsung required a "special" MHL adapter for the S3. So, I went out and also ordered that little $10 tip that converts the old 5-pin adapter to the 11-pin one. However, I'm still having issues even after using this. When I connect my phone to the adapter tip, to the MHL adapter, to the HDMI cable to the TV, and also connect the power source, I'm just seeing a black screen on my TV. The phone 'knows' that it is connected, because 1) it is charging and 2) the phone will go in landscape mode on the homescreen. The TV knows that something is connected, because I don't get a blue 'no signal' screen, but instead just a totally black one. My TV is about 3 and a half years old. It is a 42" Vizio that can output 1080p. I'm really struggling with figuring out what might be causing these issues. Could my TV be too old? I bought some really cheap ($3 each) HDMI cables online, could it be an issue with the cables? I also tried testing out the same set up on my 32" Emerson TV, but that only outputs 720p and I'm not sure if an MHL adapter would work on 720p. Any troubleshooting thoughts & ideas would be appreciated.
