RGB no input signal - Computers & Internet

The projector has a RGB input
So to use it on a VGA output from the computer you would need a VGA to RGB adapter
or something like this adapter

with a component cable
as projector has component inputs also

RGB is for a computer, unless you had one hooked up it would say no input.

Have you tried to disable the Power settings? For that go to Start, Control Panel, Power Options and in there put everything to Never, click Apply and OK.
If it happens even after that then the video chip is dying and it will have to be replaced - you will need a new video card.

This can be caused by an incorrect signal feeding your LCD. Normally, the green channel can carry the synchronizing signal along with the green part of the picture, but if it does not terminate properly it will make the whole picture green. The Syncmasters usually have Composite, RGB/Yr-y b-y, VGA and RF inputs. It could also be that the LCD is in RGB mode and you are feeding it Yr-y b-y. (or vice- versus). Make sure, if your using the component input, (RGB) that the source matches the LCD setting. RGB to RGB and Yr-y b-y to Yr-y b-y.

In order to connect your laptop to your TV using RGB, you need an RGB adapter. RGB is also known as component video; it breaks up a video signal into red, green and blue. laptops do not have RGB outputs. However, many laptops have VGA, DVI or HDMI outputs. An RGB adapter connects the single VGA, DVI, or HDMI cable to an RGB cable, which is actually three different cables tied together. INSTRUCTIONS:
1. Connect either the VGA, DVI or HDMI (in the order of increasing video quality) cable to the VGA, DVI or HDMI port on your laptop, depending on what is available. 2. Connect the other end of the cable to the side of the RGB adapter with the single input. 3. Connect the RGB cables to the red, green and blue ports on the other side of the RGB adapter. 4. Connect the other end of the RGB cables to an available component input on the back of the TV. 5. Tune the TV to the component video input you used through your television's menu. 6. Turn on your laptop. The laptop should now display on your TV screen.

Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

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.)

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.

You need to change the input signal, get into the menu on your monitor and change the signal from rgb to dvi, hdmi or vga dipending on what cable you using for connection.
There is NO rgb connector on that monitor

Good luck

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)
