[iBook] video out

[F. Allan Vogel]

List

I've got a dual usb/600/384ram - I bought one of the monster cables so 
I could hook up to a tv and show dvd's. Initially, the signal was 
scrambled, so I returned the cable for replacement. Still had the same 
problem.
Sent my Ibook back to Apple thru CompUSA - they did not advise Apple 
what the real problem was, so when it was returned it still didn't 
work.
Sent it directly back to Apple - they replaced the logic board - but - 
now I get no signal at all....
I've tried several tv's and camcorders with no success....
Anybody got any idea what the problem may be???
