Trying to use rgb input

My viewsonic keeps coming up with no signal on all my inputs. I plug into the cable (ant) and I hear sound no (pic) and it cuts out and goes to no signal. I hook up to my computer through the rgb input it works just fine. Can I somehow use the rgb input or dvi input to play cable/dvd player? I purchased a rgb cable to rca and tried it to a dvd player but comes up no signal?

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)

I cant keep my tv turned on after i pushed the rgb button by mistake it keeps on displaying no signal and then it goes off


Turn on the TV again. You need to change the input from RGB back to cable or HDMI or Component or whatever input you have a source for. If you don't know which one, look at the back of the TV and the wires you've got plugged into it.
If it's 1 round coaxial cable, change the input to Cable.
If it's three wires (red, white, and yellow) change the input to A/V.
If it's 5 multicolored wires, change the input to Component.
If it's an HDMI cable, change input to HDMI.
If you cannot change the input before the TV turns itself off, try unplugging the TV from the wall socket for about 10 seconds, and then plugging it back in. If its still on RGB, you're going to have to either find a way to get faster at switching inputs, or find an RGB cable and something to connect it to your TV. This is a last resort however.

You need to set the antenna input back to ANT A (1), you are ANT B (2) right now that why you are not seeing any signals.

I plugged in the normal 3 Video inputs and it still doesn't work.


More info is needed, please. When you say 3 video inputs, what are you referring to? I believe the Sanyo has the HDMI, RGB/YPbPr component video, S-video component, RCA composite video and Coaxial connections, though I'm not sure how many of each. So lets start with the best quality to least.

HDMI: This is one cable that provides both audio & video and produces the best picture quality. It comes in different lengths and is a wide, flat connection. A must for 1080p resolution signals.

Component video, RGB or YPbPr analog component cables: 5 separate RCA cables, 3 of which are video that separate the video signal & 2 audio cables. The 3 video cables are generally red, green and blue (RGB) or marked individually with the letters Y, Pb/Cb & Pr/Cr . The audio cables are red & white. You may see these on the back of DVD players often. They will carry a signal up to 1080i but not 1080p.

S-video component: One cable for video, it is a round connection with several pins in it and will only plug in one way. You must use 2 RCA cables for audio with this cable, red & white again.

Composite video: 3 separate cables; Red, White & Yellow. Red & White are audio, left and right while yellow is video.

And finally there is coaxial which it the cable that is identical to the cable from the pole/ cable box or your dish. It is the poorest quality.

What can happen is you are using 3 standard RCA cables and have them plugged into the component input & they will not carry the signal, or one end in component input and the other end in the composite output or vice versa. Another is that you have the wrong input selected on the menu. Check all your cables and connections, plus the input you have selected on the TV itself.

Hooking up my Sony HD Tv


Couple of items come to mind.
In the menu of the receiver, is there a way to choose video and RGB?
Set the receiver to SAT
Connect the HD Cable Box to SAT
Check the TV is on Monitor RGB.
Check the input being used by the monitor RGB cables is selected on the TV.
Have a picture? NO, receiver has issues.
Yes? Do this with each input to confirm they work.
You can reset the whole receiver to factory by holding the tone button down and holding the standby button for three seconds. (This clears your speaker setups, too.)

ViewSonic VG2030wm speakers not working


you are unable to get an image on your ViewSonic monitor, first check that the necessary cables are attached correctly and that the proper drivers are installed. ViewSonic offers drivers for download directly through its website (see Resources).

Some LCD monitors use a VGA input while others take advantage of the newer DVI interface to provide a connection to PCs (some ViewSonic monitors offer both types). When connecting your monitor for the first time, you'll need the right type of cable for both your monitor and computer. In some cases an adapter may be necessary to convert the DVI signal from your monitor to work in a VGA input on your PC.

Check that the VGA or DVI cable is tightly attached to the back of your monitor and to the back of your PC. Use the small thumb screws on the ends of the connectors to keep everything tightened in place, which will prevent the cable from getting loose.

ViewSonic monitors also use a power cable to plug into a power source. If the power light does not comes on, check that the power cable is inserted fully into the back of the monitor and that it is plugged into a working wall outlet or a reliable surge protector.

Projector will not detect a Dell computer


Computers do not generally send an RGB signal, you should be connected via a VGA cable between the projector and the computer. The input menu on the projector should be set to VGA. The output of the computer should be equal or lower to the maximum resolution of the projector.

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.
