Sleep Timer Mode

The Sleep Timer mode is an energy-saving feature that enables you to set a time for the monitor to
power on and off at the same time every day. This also extends the life of the backlight bulbs in the
monitor. The Sleep Timer has five settings:
? Set Current Time
? Set Sleep Time
? Set On Time
? Timer: On/Off
? Sleep Now

To set the timer:
1. Press the Menu button on the monitor front panel to display the OSD Menu.
2. Scroll down and highlight Management.
3. Press the OK button to select Management.
4. Scroll down and highlight and select Sleep Timer > Set Current Time.
NOTE: You must set the current local time before you reset the time for Sleep Time or On Time. Note that the time is displayed in a 24-hour clock format. For example, 1:15 p.m. is displayed as 13 hours 15 minutes. A power failure or loss of power to the monitor will cause the timer to reset to 00:00. If this occurs, you will need to reset the sleep timer mode.

5. Press the OK button once to enter the adjustment mode for hours.
6. Press the - (Minus) or + (Plus) button to adjust the hour.
7. Press the OK button again to enter the time for minutes.
8. Press the - (Minus) or + (Plus) button to adjust the minutes.
9. Press the OK button to lock in the time chosen.
10. After setting the current time, the highlight automatically skips to Set Sleep Time. Repeat steps 6 through 9 to set Sleep Time.
11. If you do not want to set Sleep Time, press the OK button twice, then select Save and Return to exit the menu.
12. After setting Sleep Time, the highlight automatically skips to Set On Time. Repeat steps 6 through 9 to set On Time.
13. Set the Timer mode to On to activate the Sleep Timer settings.
14. When you are finished, select Save and Return to exit the menu.

The fifth selection, Sleep Now, turns the monitor backlights off immediately and stays in sleep mode
until the next On Time activates or a monitor button is pressed.

Programming the Sleep Timer:

1. Press and release the TV key.
2. Press and hold the SLEEP key for three seconds. The illuminated component name turns on.
3. Release the SLEEP key.
4. Using the number keys, enter the desired time in minutes (from 1-99 minutes). To set the timer to an umber under 10 minutes, first press 0 and then the desired number (e.g.,05 for five minutes). The illuminated component name blinks with each key press.
5. Once the second number is entered,the illuminated component name turns off.
   Tip Any key press other than the number keys is ignored. If you don't enter the sleep time within 10 seconds after pressing the SLEEP key, you must start over at step 1. The illuminated component name blinks four times and then turns off, indicating your attempt to program the Sleep Timer has been unsuccessful.
6. The Sleep Timer is now set.
7. Leave remote aimed at the TV. Once the Sleep Timer is set, you can continue to use the remote without affecting the Sleep Timer. However, because the timing mechanism for the Sleep Timer is built into the remote itself, the remote must be in TV Mode and pointed at the TV to activate the Sleep Timer.
   Note: If the ON·OFF key is pressed, the Sleep Timer is canceled.

Welcome to FixYa.

Check the "sleep timer" settings. The sleep timer automatically shuts off the TV at a given time. It can be found under the settings or system menu.

I cannot provide you with further details on how to go about it as you have not provided the specific model number of your TV.

You ca post your question again along with the specific model number of your Hitachi TV.

Thank you for using FixYa.
Have a great day.

Try unpluging your T.V. for 5hours+, then turn it back on. Worked for It's called a "hard reset" by sony.

Otherwise
Do the following steps

1. Check the Sony remote for a button labeled "Sleep." This allows you to cycle through the sleep settings and determine how long you want the TV to remain on.
2. Step 2 Press the "Sleep" button. You'll see a number come up onscreen: usually 15 or 90. When you press it again the number changes, moving up and down in increments of 15. This is the number of minutes the TV will remain on before it goes to sleep. As you cycle through it, you should see a setting with the words "Sleep Off" appear onscreen. If you leave it there, the sleep setting should cancel, allowing you to turn the set off when you like. If you miss it, just keep pushing the "Sleep" button. It will continue to cycle through the options until "Sleep Off" appears once again.
   
3. Step 3 Access the timer function to shut off the timer by pressing the "Menu" button, then cycling through the onscreen options until you reach the "Applications" setting. Press it, and then cycle through to the "Clock/Timers" option.
   
4. Step 4 Highlight the "Timer 1" setting and press the "+" button. If it's showing a given time, you'll need to deactivate it. Use the up and down arrows and move through the possible options until you come to the "Off" setting. Leave it there; that should shut the timer off.
   
5. Step 5 Repeat the process with the "Timer 2" setting, a little further down the "Clock/Timers" menu. Set it to the "Off" position just as you did with the "Timer 1" setting.
   
6. Step 6 Press the "Menu" button when you are done to exit the menu and return to the screen. You should be able to view the Sony TV as normal with no danger of it turning off.

good luck
