I've had the same problem with a 60" proscan. The tech repaired it ($400 for the repair) and left a note inside the chasis explaining what he did (in case he had to fix it again). He replaced a resistor and re-soldered a number of ICs. It happened to me again, and I may attempt the repair myself this time around.

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 turns on then off no picture


this is very common. it is the power supply going bad. it should run at 130 volts dc. but it is now running much lower that this. just enought for the tv to come on. but not enough to power all the circuits right.

My Hitachi 57F710 TV turns off as soon as it turns on?


The model indicated is a DLP which uses a lamp---lamp will not usually cause set right on and then instantly off----takes it 15 seconds or so if lamp has failed.

Also set has led on front that may blink.

If instant it is turned on it goes off----you have a short likely in power supply or elsewhere.

If you have more information or a question press the "make a comment button" on this page.

Tv has been turning off right after you turn it on then after a few attempts it would stay on now the power button on front turns green, it tries to come on but then turns off.


Sounds like high voltage power supply has gone bad. You can try purchasing new PS online and replacing yourself if handy or you will need to bring in for service.
