Tv timer shuts off


If the TV gets very hot it maybe shutting down on its own accord however there should be a way to navigate to the sleep menu through the buttons on the front of the set.

Have a proscan ps50700 that wont show the picture, will turn on but turns itself right back off. what could it be


TV Doesn't Turn On
  • Your RCA rear projection TV may not turn on from time to time for several reasons. First, check that the power cord is plugged into a working power outlet. Check that the outlet is receiving electricity by plugging a different device into the outlet. If the other device doesn't work, you may need to replace a fuse or reset a circuit breaker in your home.

    If you tried using the remote control to turn on the TV, press the "Power" button on the front of the TV. You may have a problem with the remote control if the TV turns on.

    If you tried using the front control panels and haven't tried the remote, press the "Power" button on the remote control. The television controls are blocked if the TV turns on with the remote. To unlock the controls, open the "Parental Control" menu and remove the check mark next to "Front Panel Block."

    Finally, your TV may be performing a diagnostic check. These checks are used to find any errors in your TV. Wait a few minutes before trying to turn on the TV again.

TV Turns Off By Itself
  • You may find that your RCA TV turns off by itself on occasion. This is often because the "Sleep Timer" feature was enabled. This feature allows you to place a timer on the television that will turn it off after a specific amount of time has passed. The feature allows you to save on your energy bill and extend the life of your television.

    If the "Sleep Timer" wasn't set, the television may have detected a power surge in your home and shut off automatically to protect the components of the television. Wait at least 30 seconds before turning the TV on again.

    Finally, if you suspect the television is turning off for a reason other than a power surge, unplug the television and let it sit for at least 10 minutes. This will clear any errors in the television. After 10 minutes, plug the television back into the outlet and resume normal use.

  • Blank Screen
  • A blank screen on an RCA rear projection television is usually caused by a loose connection or an incorrect setting. Check that the coaxial connection on the back of the television is secure or, if you're using an external device such as a DVD player, the video cables are secure. Press the "Ant/Cable" button to switch between tuners if you are watching television, or the "Input" button to switch between input channels if you're watching something from an external device.

Tv goes off by it self i turn it back on goes about another 20 mins goes back off


Have you went through your menu options to see if it has a SLEEP TIMER set up? Your SLEEP TIMER may be on. If it is then it will automatically shut down when specified.

My TV shuts off after a few minutes


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.

Tv switches off after 5 mins


There might be three or more reasons for this:
1) The sleep timer may be on causing the TV to turn off after a preset time.
2) If sleep timer is on and no signal from the remote is received for a preset time (Samsung: 15 minutes) the tv will turn itself off.
3) The TV may have been turned on automaticaly with "On Timer". If so, and no signal is received for a preset time (Samsung: 3 hours) the tv will turn itself off.
4) A fan is not working or a vent is blocked causing the TV to overheat and turn off.
For 1) thru 3), go to the "setup" menu and make sure "sleep timer" and "On Timer" are turned off.

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.

Wharfedale lcd 1710af. switch TV on, a time of 4.59 comes up on the screen, it then counts down and switches off. The sleep timer is switched off, any ideas?


Can you set the sleep timer, or does it just stay at the 4:59? Try setting the sleep timer on, if possible, to something different than the 4:59 and let it shut off. Then turn it back on and see if you adjust the sleep setting from ON to OFF. If this doesn't work, try unplugging the TV for 24 hours and plugging it back in. This should reset the TV.(fingers crossed!) I am not familiar with this brand of TV, but if this fails to work, you can contact the manufacturer and speak with a tech. to see what your options are. Hope this helps...
