MBP 2010 - HDMI output not working!

[h2009]

Hi,
I've got an issues with my HDMI output - most of the time when I connect to my tvs the laptop doesn't display anything on the tv (although its detected) my tv's just say searching.

Other times it works fine. Does anyone know what I can do about this or is a repair job?

How are you connecting to your HDTV? If you're using a MiniDisplay port to HDMI adapter it may simply be defective.

I had the same problem connecting to a projector. Thought it was the adaptor. I took it and my MBP to the Apple store. It was the MBP.

I was having a similar issue. Turns out the MBP HAS to be on the discrete Nvidia chip. Not sure if your circumstances are at all the same as mine, but definitely make sure you are using your discrete chip.

Either way, I hope you find a solution!
