How do I change the clock on my sony bravia tv?

Press the HOME button on the remote. You want to find the CLOCK/TIMERS section. Navigate to SETTINGS. Use the arrow keys to select item. Use the arrow keys to set current time. Press RETURN to display the confirmation. Select YES to save the changes.

I have a sony bravia that turns on and immediately shuts down and the red timer light comes on. I can't get the tv to turn on. We have cable and the cable is working well but the tv doesn't respond except for the timer light. Is there anything I can do to reset the timer and get the tv to work.
