The power supply may have gone into shut down mode due to problem in the power supply such as bad DC filter cpas, or shorts circuits in the backlight inverter board, those are the two areas you need to check first.

While trying to change channels, my t.v. displayed ''no signal'' and then shut itself off. Now, when I turn it on, it says no signal and turns itself off after a few seconds.


Turn the television on and as soon as the screen turns on repeatily press the input button or change the input to whatever input you are using from a source device. As long as you change it to anything other than RGB.

Your television is essentially a big computer monitor with multiple inputs and a tuner. When using your computer and shutting it down the monitor will go in a power save mode. You don't need to shut off your monitor due to this power saving mode. When you power up your computer your monitor automatically turn on.

With the VIZIO and the RGB (computer) input the television will act just like a computer monitor. When you have a computer connected it will power down automatically when you shut off your computer. When you turn your computer on the VIZIO will automatically come out of standby mode. This is through RGB only.

This is normal operation for the VIZIO but can see confusing when nothing is connected to the RGB input. If you change your television input to RGB it will sense no signal on the input and will go into standby mode after about 5 - 10 seconds. If you were to send a signal to the television through RGB it would automatically kick on.

TV keeps shutting off automatically


Since your plasma is less then a year old, I would suggest to contact the manufacturers to get it fix under warranty. If the plasma keeps shutting off by itself, that is not normal and should be repair.

In RCA T13208 13 in. TV/VCR Combo shut down after turn it on


The safety circuit is sensing a problem and is why it will not let the tv stay on,the cause could be a problem on the mechanics of the vcr,you need to get an estimate to see if it is worth the repair and might be able to keep using just the tv.
