I found that there may be a problem with pins of the SD card reader but I can't find anything wrong.

The pins on the right touch when the SD card is inserted but not with one on the extreme right. Is this a problem?

  • The pins aren't touching, like at all? Of course this is a problem, how else would they function? – Jacobm001 Jun 21 '17 at 18:15

If you think the SD card slot is damaged, then you can attempt a repair (not recommended), or return the Pi to the seller for a new one.

The number of times the LED blinks is indicative as to what the problem could be:

  • 3 flashes: start.elf not found
  • 4 flashes: start.elf not launched
  • 7 flashes: kernel.img not found
  • 8 flashes: SDRAM not recognised. You need newer bootcode.bin/start.elf firmware

I recommend trying a new SD card just to be certain its not the SD card slot.
