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.

Hello, I have a Sony KDS-55A2000 and it works fine for a couple of minutes and then it switches off and the green led starts blinking for about a minute and then the picture comes back and works fine

First thought would be the lamp may be about to fail if it has not been replaced in a long time---a warning will be the picture is a bit darker than before and takes longer to get bright than it once did.

Samsung DLP 62 inch turns off by itself after being switched on

take off the lamp access door on the back and find the safety switch that the door pushes on. unplug the connector from the switch and put staple into the connector to short out the cable. Switch is probably bad. worked for me. same problem.

We have a Hitachi C28W1TN, which is just under 10 years old that has recently started switching itself off. It goes onto standby by itself and when we switch it back on, it instantly does it again. At...

It's been a while since this post, but I may have had a similar problem with my Hitachi. With no reason it would switching on and off randomly. The problem was with a solder joint on main relay - it was cracked and would not keep the coil powered so i kept flickering on/off. This relay is located on the front of pcb, between high voltage area and the switch and on my tv it is blue. Check all four joints and apply some new solder onto them. Make sure the tv is not connected to mains ;-) Hope this helps
