TV turns itself off?


I am sharing four cases in which your tv either turns itself off or appears to turn itself off.

TV appears to be off
  • You using your tv as a monitor or your pc is in sleeping mode.
  • Your cable or satellite Box is not outputting a signal.

TV turns iteself off
  • The sleep timer is set.
  • The off timer is set.

Your tv appears to be off:

If you are using the tv as a monitor If you are using tv as a monitor and the stand-by light only
blinks for a few seconds when you press the power button,your pc is in the sleeping mode. To take your pc out of sleep,press a key from your key board or move the mouse.Tv turns on.

If you are using TV with a cable or satellite Box

If you have a cable or satellite Box your Tv may appear be off because the cable or satellite Box is not outputting a signal.Press the guide or info button on the cable or satellite Box remote control.

if the screen displays info or guide data,the problem is caused by the Box,you must call your cable provider.
if screen does not display info data,change the source on your TV.

How do I set the sleep timer? We got the tv from a friend and it had no manuel.


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.

When your tv turns on by it self you prob have the alarm set. For the tv to turn like a clock would go off when u need to get up. You need to check the the sleep/ wake up timer to see if it is set.

RCA HDTV model#HD52W59. When I turn the power on it stays on for a few seconds and then goes off by itself.


TV turns off unexpectedly
• Sleep timer may have been activated.
• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on again. If this
happens frequently, the voltage in your house may be abnormally high or low.
• Unplug the TV. Wait ten minutes. Then, plug the TV in again.
