Well, for my Mobility 7500 I have to make sure I do this:

1. Have the TV-out cable plugged in before starting the laptop. 
Alternatively bend a staple to form two prongs which are stuck in the 
left two holes of the svideo plug (it simulates a cable). Then you can 
swap it with the cable when you really need to.
2. Turn it on, log in, set resolution to 640x480.
3. atitvout pal && atitvout -f t
4. Watch some anime
5. atitvout -f l

If you do things like use APM or unplug the cable you may not be able to 
get back to TV. Even if you do the above you may not be able to switch 
to TV more than a few times. Hope it helps.
