I have bought a new TV: a Loewe Nemos 32. I have tried all the Loewe codes, but I cannot manage to get the "TV input" button on the Yamaha remote control to work. With my other TV, a Philips, everything worked fine all with the Yamaha remote control. Now with certain codes the volume can be changed, switched on and off, change channels, etc...but not that "TV input" button. Can someone help me with this, does someone know which factory code should make all buttons work with the Loewe? The receiver has no learning possibility.
