Macbook Pro to HDMI LG TV

I have a Macbook Pro OSX 10.8.2 that was manufactured in the 3rd week of January 2010. I am attempting to connect it to LG 1080p TV. I have the mini adapter for the Mac with the HDMI receptacle on it. I plugged in the Mini adapter with an HDMI cable running to the TV. I selected mirroring in the system preferences, it shows connecting and on the Mac it shows the match to the LG TV and will go back and forth between a blank screen and a snowy screen, but no picture ever appears. I'm wondering if the Mac is just too old. Any ideas?

Hi Mom51035,

If you're having trouble getting the TV to display the MacBook Pro's video, I would recommend looking through this article and trying the troubleshooting suggestions to see if you can resolve it or at least determine the source of the issue:

Do you have the TV input set to the hdmi port that the cord is plugged in to? Test out with multiple hdmi cables it may be a bad cable or adapter.

I have the same issue, I have 2 Mac's, Mac book pro and Mac air running OS X 10.8. I am usually pretty handy with this stuff and nothing I have done or looked for has been able to figure this out. My computer detects the LG tv and even detects it as an LG TV however the TV continues to say no signal when trying to use it as a display. I'm certain this issue is related to the TV/Mac interaction but there are no good answers out there. Please help if you found the solution! thanks

I had this problem plugging in to HDMI3/MHL on my LG smart TV.

After some head scratching and it working on a Sony, I went back and tried HDMI 2 input. Works fine. Guessing something to do with MHL added functionality that confuses things. Not sure if this was your problem thought.
