Since this thread hasn't had activity in a while, we're going to close it to keep content fresh.
We hope you were able to get the help you need but if you're still having trouble, you may try to choose a different brand from the list, which in your view has the same country of manufacture as the TV. You may also search for TV remote codes online and see if any other brand matches the same code as Schaub Lorenz, and select that other brand instead. However, please take note that this step may or may not work.
If you still have other questions and concerns, feel free to submit another post and provide as many details as possible so that others can lend a hand.
Hope this helps!
