Raspberry Pi won't give any output.. where to start?

[ljump12]

I just received the raspberry pi today, put in the SD card, attached the microusb cable, and attached the HDMI cable to my TV. I see the Red "power led" turn on, but no video. I then tried to attach the analog video to the TV, and still nothing.

I'm not really sure where to start in terms of troubleshooting... I know the HDMI cable works because it was jsut plugged into the PS3.

If anyone has any thoughts, that'd be great!

I have the same issue. My SD card is a Sandisk ultra 30MB/s -10, 16 GB. I have also tried a Sandisk ultra 30MB/s-6,16Gb and a San Disk 4GB-4.

Plug in, red light comes on, green light flashes once.

My experience:

There is no TV/HDMI output until AFTER the Raspberry Pi has booted from the SD card.

If the red light is on, assume you have power. Watch the green light next to the red power LED when you power up the card, it shows read activity in the boot sequence.

If the green LED
- is faintly dim, there is no SD card.
- blinks once, then the firmware can't be loaded*
- 3 flashes: start.elf not found
- 4 flashes: start.elf not launched
- 7 flashes: kernel.img not found

*firmware not loading:

You need to create an image of the software onto the SD card. This is different than copying the the file to the SD card.

In my case I had the "Hynix" chip and I needed version 2013-02-09-wheezy-raspbian.zip (or later) from the downloads page. The soft-float release currently (3/20/2012 @ 7:54 PST) has an old date of 2012-02-08 which may not work with the Hynix chip.

I also found this wiki informative, but it did not mention my specific problem:

Figured it out. Turns out my sd-card wasn't pre-loaded with an OS. Once I installed that, it worked like a charm!

I downloaded win32diskimager-v0.7-binary.zip and 2012-12-16-wheezy-raspbian.zip. after unzipping the diskimaging file I had Win32DiskImager.exe. I used this to write to the SD card.

My green light flashes once only. then nothing.

Try using the latest Raspbian image. The memory chip on some of the latest boards doesn't work with the older images. You get 1 flash to show the boot code is loading and then it locks up.

Try 2013-02-09-wheezy-raspbian.zip as mentioned earlier in this thread and in many other posts on the forums. 2012-12-16 is too old.

OK

OK, this explains why my brand new rpi 2.0 won't boot off the same cards my other rpis boot from just fine. The problem I see right now is what if we want to use mono. There is a hard float alpha that breaks when you do anything ui related and the soft float wheezy is 8/8/2012? Any ideas if there is a solution for this situation outside of hurry up and wait?

Copy the *.elf, *.bin and *.dat files from the working Raspbian image to the DOS partition of your soft-float Debian SD card (backup the contents of the partition first, of course).

Had the same problem, pi would not boot. Used win32diskimager-v0.7-binary.zip on Windows 7 to write 2012-12-16-wheezy-raspbian.zip, after unzipping the diskimaging file, and writing to 3 different SD cards. The green light flashed once only, then nothing. Messed around for a week with no results. Found this post, and followed the advice to get 2013-02-09-wheezy-raspbian.zip . That fixed it. It's booting now. Thanks so much for the help. I appreciate it.

When you type a password in Linux it doesn't show any characters, this is a Linux security feature.
Just type the password in, pretending that its working and press enter.
