Logitech Harmony One

Category: Media Centre / Tag: , , ,  / Add Comment

I bought a Logitech Harmony One remote for our Home Media Centre/Theatre/Blu-ray/Sky HD mutant setup to replace 5 remotes with one and had a lot troubles getting it to work with our crappy tv which is Philips 42PFL5522D/05. If you own this tele and you just bought Harmony One save your self some time and choose 42PFL5522D and not 42PFL5522D/05 as model of TV when setting the remote up. This will make switching inputs work.
