Assuming it is not hardware but soft settings...
1) Check and make sure that your TV does not have the timer set.
The Timer feature allows you to set a day and time for the TV to turn on automatically and the device and channel to display when it switches on. If the TV is already on at the requested time, the TV automatically tunes to the channel you designated in the Timer menu.
When the Timer turns on the TV, the following message is displayed: "Press a button for the TV to stay on." Press any button on the remote control within five minutes if you wish the TV to remain on.
Note: The TV clock must be set before you can use the
Timer feature (see preceding page to set the clock).
On/Off
Press down arrow / up arrow to enable or disable the Timer.
2) If not working, try SYSTEM RESET. Press SYSTEM RESET button on the front panel with pointed object (e.g. straight paperclip). TV turns off, green LED flashes for about 1 minute. When it stops flashing turn the TV on again. All settings other than Parental Lock need to be set again using the manual.
3) TV RESET. If all else fails for soft error. Your manual describes this last resort for soft type error. It could be hardware problem needing more expertise.

Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TV will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.
Good Luck Ed Pinero

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

Power Light Shuts Off
If the power shuts off during game play (even as much as 30 minutes after the system is turned on), then turns off and won't turn back on or the fan isn't working, the system needs repair.

Power Light Flashes
If the power light flashes once when power button is pressed, then turns off and won't turn back on, the system needs repair

That hapened to me once and the solution that worked for me was unpluging the TV for about 5 minutes and pluging it back in, you may just need a new remote though.

Replace the capacitors in the DM board or the lamp is defective.
