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.

Mysony wega KDP-57WS655 press power button straight to standby flashing 10 times

Indicates a problem with the high voltage circuit. You could try unplugging the power cord, plug it back in and try again. If that doesn't work unplug the power cord again but leave unplugged for at least five hours and try again. Still doesn't work find a local repair shop that works on sony tvs and have them fix it for you.

Ok, I have recently been the fortunate one in my family to be given a Philips proscreen 4600 b projector. The only problem, so far, is it will not turn on, at all...think that's why it was given to me...

Hello, welcome to Fixya!

Your unit is having a power fault because it is not switching on. The unit might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. If it doesn't power on, plug it into another outlet, to make sure there electric current entering into the unit.

If plugging into another power outlet doesn't power it on then it confirms that the unit is having a power fault.

When electric current comes from the power outlet into the unit, it goes straight into the power supply board which then circulates the current into the unit. So if the receiver doesn't power on, the first thing is to make sure there is power entering into the unit.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board. Once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect and solve the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

T.v is not getting any power.

Try unplugging the power for at least 10 minutes or more then plugging it back in.. If that doesn't work you may blown the transformer or fuse in the unit. If your unit doesn't have access panel for a fuse for the power supply it will need to be sent for service.

A continuous flashing red light with the word LAMP on it would definitely mean you're going to need to spend a few bucks on a new lamp....or for a few more, upgrade to a TV from this century that doesn't require lamp changes :)
