If your external monitor turns off along with the LCD, then it's definitely a GPU issue.
Good luck.

In that thread Stuart reported they replaced the LCD and the cable. His problem must have been different from mine, since on my T42 the display turns off on the LCD *and* the external monitor, whether they're running in tandem or separately. So it couldn't be the LCD, and if it were in the cable I don't think it would affect the external monitor. If this is caused by the infamous T4x graphics chip solder fracture, as Chris suggested, then it's yet another manifestation of that problem, in addition to the other symptoms I've read about.
