Sorry if this seems too obvious, but have you checked to make sure you haven't inadvertently dimmed the screen? Function + Home key will brighten the screen.

you have turned off the display or you have set the brightness to zero.

The other possibility is that the backlight burned out. The T60 is old enough that it uses a CCFL (a small fluorescent light bulb or bulbs). Those tend to start burning out after about 5-7 years, which is right around the age of a T60.

If that's the problem, the good news is they can be replaced. The bad news is it's not really a do-it-yourself job unless you're very comfortable with electronics. You pretty much have to half-disassemble the laptop and screen, and there's a dangerous high voltage inverter in there which drives the CCFL (in fact sometimes the CCFL is fine and it's the inverter which has failed). So you'll probably end up paying a laptop repair shop to fix it for you.
