Question about Proscan PS27500 27" TV
I pressed the power button and it starts to turn on and then it clicks off, and then it clicks back on again, thus turning itself off completely. Seems like a lot of static magnatism coming from the picture tube after it turns itself off the last time. Any suggestions? My Proscan 27", model PS27113 would not turn on after a power loss. I unplugged for couple hours and it turned on; however, it won't come on again after shutting off without several tries and waiting some time. There is no control voltage to the front switches when inoperative. When finally get back on I have 18 volts. Does anyone have any suggestions. Jim
If you want to eliminate magnetism, you have to degauss the screen, if you don't know how to do that, here is a small guide for that: http://www.wikihow.com/Degauss-a-Computer-Monitor
but that strange shutting down its the transistor... so your best choice is to send it to a repairman to change the transistor..
if you try to do that for your self, you could even get shocked with the electricity contained in the tv... even if its turned off and unplugged..

Tips for a great answer:
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.
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.
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.
