Yup. You gotta enter the service menu:USE AT YOUR OWN RISK!
1) Hit SLEEP
2) Hit VIDEO STATUS + DISPLAY
together. You'll see the service menu.
3) Hit the number 2
. You'll see another screen with 4 digits at the bottom left: like 0045 or 00A1, etc.
4) It's in Hex, so fire up your Windows calculator, switch it to Scientific mode, choose Hex as input, enter the digits and switch back to the Digital mode. You'll see your total hours in digital. Btw, leave the first few 0's out in Hex (eg: for the above, enter only 45 or A1, etc.).
