No input is detected on rgb - Hitachi CP-S210 Multimedia Projector

Hi there, i have connect my laptop through a new VGA cable to IBM projector C400. My laptop detects the projector but the projector doesn't detect the laptop, What should i do?

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.

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.

There are several input that you will have to select. RGB for input from computers. There are also video imput selection if you plug it into a DVD player.

The problem of course is not the computer since you communicate well when using the Samsung TV. The problem is your Sampo. The Video Ports are:
Composite Input (Shared w/ S-Video) RCA-pin x 2 S-Video Input (Shared w/ Composite) Mini DIN 4-pin x 2 Component Video Input RCA-pin x 2 Sets (Y/CB/CR, Y/PB/PR auto detect) DVI Input (with HDCP) DVI-D 24 pin x 1 RGB Input D-Sub 15-pin x 1
If the RGB WILL NOT COMMUNICATE, I suggest you try RCA/DVI/ or shared composite. You may need adapters, but with so many options, just try other methods.

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.

MIne did this at first. Unplug from source for 2-3 minutes, then try again to turn on. Should come up then.

Hi mrus821

If the signal won't go through you will have to either have your Mainboard Repaired or Replaced.

This is unfortunatelly a common Mainbaord problem , and the above is the only way to get it fixed.

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)
