RaspberryPi3 powering up but no visual HDMI - VGA

wolfmountaingames

I recently got a raspberry pi, but all my monitors are VGA so I went to the store got an HDMI to VGA adapter, and plugged in the screen, mouse, keyboard, and finally the pi. The red light came on so the power cord is working, but there was no visual at all it was as if the pi was not on. I read somewhere that in an older version if you changed a line in config.txt that it sometimes help with hdmi to vga, but I can not find config.txt anywhere on the preloaded card I bought. Can someone help me with this or link me to a confirmed working HDMI-VGA adapter that works with the pi?

 

Thanks,

  • Hi Andrew,

    I am a bit worried about that SD card you have....

     

    There are two hints that this may be the problem. I don't hear anything from you about the green light flashing a bit when you turn on the pi. The green light should go on and off irregularly for a while after you turn on the pi. If NO green light is seen at all the pi is not seeing the SD card.

     

    Secondly, you say something about not finding config.txt. The SD card should have a boot partition which holds the stuff needed for booting. It is a fat partition that should be visible using Windows. And there you should be able to find "config.txt", simply in the root directory.

     

    (Hmm. I don't know how NOOBS handles booting and if you'd be able to see that config.txt file on a NOOBS card. )

    When a Raspberry pi boots, the GPU will start and load "bootcode.bin" from the SD card. That contains code to do the things that config.txt tells it to and then load "kernel.img" and start the CPU.

     

    All that already causes some flashes of the green led. If you see no flashes, no communication with the SD card is happening. Card not inserted? No "bootcode.bin" on the SD card? stuff like that.

     

    So for both of you, I'd simplify things by just getting a raspbian image and put that on your SD card according to the instructions you can find online. Then you CAN see config.txt and edit if necessary.
