Getting a no RGB signal on my vizio tv model #E371VL any suggestions?

Try changing the input on the television with the remote or on the television control panel. Apparently you don't have anything plugged into the RGB connections.

Blue screen that says RGB on my vizio

I'm sorry for the difficulties you're experiencing in watching programs on the TV. Since the screen says RGB, it appears that you've selected input as RGB(VGA, also known as PC input). If you have nothing connected to PC input (RGB), please change the input to HDMI or component or what ever it is by using the input button on the Remote of the TV.

In some TVs INPUT Button is labeled as TV/Video. Press it repeatedly to change the input from one to next.

Thanks for understanding. Please let me know if you require any clarifications.

Trying to hook my home PC into my LG TV gets me the message Invalid Format, what can I do to get the signal or can i use this tv for my monitor with a dell PC

Connect VGA (D-sub 15 pin) cable from PC to TV (RGB PC) input jack. Connect audio cable from PC to TV. Set screen resolution on PC to be compatible with TV, such as 800 X 600 or 1024 X 768 etc. Select on the TV, the PC INPUT using the TV remote when ready to use as monitor.

Under PICTURE on the TV select SCREEN (RGB-PC). You can AUTO-CONFIG or you can set resolution manually to the same you set PC to. Other adjustments can be done here as well to get optimum picture on TV from PC.

Stuck in RGB input.

i imagine your problem is over by now one way or another, but for anyone else experiencing this problem, thought i would share. your rgb input is tripped and needs to be reset, there are multiple things that "may" fix this, but the sure fire method is to connect a laptop to the rgb input, make sure you change your display settings on the laptop to "external monitor" and change the monitor selected in display settings on your computer. When the TV recieves a signal (which is what it is wating on and why it is frozen) it will then allow you to change input and will not turn off. Make sure your computer is running and all display settings are set before turning on tv so it does not time out and shut off before you can get it to pick up the signal

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.

LG 32LG30 no signal when pc and tv r connected via rgb cord

For No signal try- Updating your Video drivers, and making sure it shows a connection on your laptop ( by going to propertys on desktop and then dysplay)
For format try- Updating and or turning down the screen resulotion becuase the size differs on screen even if you think it shouldnt.

Trying to use rgb input

Cable TV: Connect the LCD TV to the cable with CATV and Digital cable. Preset the cable TV channels into memory with Auto Scan function when using a cable TV system. Make sure you set the INPUT SOURCE properly (TV, VGA, S-Video, etc)
