Switching CRT to LED with 'input not supported" in Vista


It sounds like the computer is sending a signal to the monitor, but the monitor is not happy with the signal.

First, I'd check the cables. Make sure they're all plugged in solidly to the right ports. If you have a spare cable, swap it out to see if it helps. Note that Component Video is not the same as RGB, so you can't just plug an RGB cable into Component jacks.

Did the monitor come with software that needs to be installed? Make sure that's installed.

Check the monitor manual for what kinds of input it can accept. Check your computer's manual for what kind of video output it can produce. Make sure you're using a protocol that both can work with.

Try connecting the monitor to another computer. Maybe the monitor is faulty.

Try using a different video protocol. If you were using your computer's HDMI port, does it have an RGB port? Can you use USB?

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.

How to turn on rgb from lap top to tv.


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.

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.

    How do you hook up the tv thru dvi out with a sony pcv-rs620g


    There are several ways to do this. The two best are:

    1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

    2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

    Currently, I am using option 2 for my own use.

    In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.
