Raspberry Pi Forums

I have been using a Raspberry Pi Modal B (Origional) for the past three months(ish) and have started to have a problem. I leave it plugged in, connected an ethernet cable and inside a case (from ModMyPi). I normally use SSH to access it when ever is necessary. Yesterday I tried to connected to it, but upon scanning my network it was not listed. I dug out out from behind the router and discovered that the green OK light was off, and only the power light was working. I connected it to my moniter (which it has worked with before) and saw that it was unable to find the OS on the SD card. I decided to reinstall the OS (Wheezy 2013-02-09). After installing it and rebooting the Pi, it showed nothing on the monitor and the green light does not light at all. I checked the elinux board and tried replacing the bootcode.bin but it still won't boot. Any ideas?

FAQ:

• It is at room temp
  I have not modified the board in any way
  The SD card is not 'Locked'
  The HDMI cable works
  I am using a 5v phone charger to power it
  If I press down on the SD card when I plug it in, I get three green LED flashes, which means start.elf was not found or loader.bin was not found. I have checked the SD card, and start.elf is there, however loader.bin is not. According to ELinux, loader.bin is not needed.

The wire spring contact at the back of a friend's RasPi failed.
Even with an SD card inserted it refused to boot as it didn't detect it.
He bent the wire to make sure it made good contact and all was well.

You say you get some flashes if you push the SD card, wondering it it's a dodgy contact?

Yes, I am considering that now. Since my Pi isn't working anyway, I'm going to go and try to sort out the pins myself and hope I don't break it!

Right now I have the similar problem.
I flashed 2013-09-25-wheezy-raspbian.img with "dd".
Here is the list of files from "boot" partition:
bootcode.bin
cmdline.txt
config.txt
fixup_cd.dat
fixup.dat
fixup_x.dat
issue.txt
kernel_emergency.img
kernel.img
LICENSE.oracle
start_cd.elf
start.elf
start_x.elf

And when I try to boot the board, I have no output on the screen, and green "OK" led blinks four times.
My HDMI cable is fine, it works with STB.
I tried to connect the micro-usb cable to iphone changer, HTC charger and PC.

What may be the reason of the problem?
