I couldn't figure it out either between my PS3 slim and LG 47LH85.
Made sure it's enabled on in both the PS3 and the tv. Tried multiple inputs including HDMi 1.
I'm thinking LG Simplink works better with LG branded devices only.
I may try a different HDMI cable when i have one available.
Yeah, that's what I would too
I chat with LG technical support and they say it only works with LG branded products.
But isn't "simplink" a variety of the HDMI-CEC standard?
And I have seen some people from other forums say it is possible to link while others say it's not.
I hope it can be done.
Let me know if yours worked
