ISDN is the ethernet cable. That won't work. You'll need a Mini-DVI or Mini DisplayPort adapter depending on the model of your MacBook.
To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info (and then System Report if you’re running 10.7 Lion). When System Profiler comes up check the Model Identifier and post it back here.

feel so stupid, because it was so late in the evening and had some wine, I made writing error and meant HDMI and ofc not ISDN, so connected the HDMI cable and on the tv I then see the Apple "Big Bang" but thats all - I think what I should see is my computer desk top ?
(sorry for my English, i am Dutch)
kind regards and thanks / Nanda

You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to use the MacBook’s keyboard and trackpad to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor.
