got no video from a r400 thinpad lenovo running XP pro only sound. What can I do?
Hi alro Welcome to D-A-L
Have you tried getting the latest Multimedia updates for your R400.
If you go here: Lenovo Support & downloads - Drivers and software - ThinkPad R400 and R500
Then download the correct update for your multimedia player.
Either InterVideo WinDVD player update or the InterVideo WinDVD software update.
Because it could just possibly be a corrupt driver causing the problem.
