I'll second this thought.I don't think you can with the peanut remote. Use the remote for the tv instead.

Chris, nice find, contrary to all the "experts". It doesn't make sense but it does work, the Mini stays ON! BTW, it looks like it works the same way on the HR54. Unfortunately, the crappy LG TV goes back. BTW, one of the HDMI inputs just died on the TV and it is only 2 weeks old, great reliability LG!
