That sometimes means you have to turn on your monitor before booting. The Raspberry PI (and its Raspbian OS) is designed to output a HDMI signal, but if it doesn't detect a HDMI device connected it will default to generating a composite signal on the RCA port (or 4-pins 3.5mm A/V jack on model B+). If it makes it past this and no further, then the problem is once again in the hands of your power supply.Įven when booting sometimes you won't immediately get a video signal. If you've got your Raspberry Pi connected to a display, recent versions will also show a kaleidoscopic boot screen. These are available cheaply, but they can often be found bundled with the SD cards themselves. However, we have experienced problems with several SD card readers – especially those embedded within laptops and netbooks – and we'd suggest switching to a standalone reader first to see if that helps.

Our Raspberry Pi installation guides for Windows, Linux and Mac OSX covers three different operating systems, so it might be worth trying a friend who uses something else. Take a look at something called a checksum and make sure the checksum for the files on the card is the same as the checksums for the original files.Īs these read errors are more likely to be an indication of either the SD card not being read correctly, or the Raspberry Pi operating system not being written correctly, we'd recommend trying to get hold of a new card first and writing the image with a different method. It is possible to troubleshoot these problems by looking for the files involved and making sure they're correct. You need newer bootcode.bin/start.elf firmware, or your SDRAM is damaged.įor devices made before October 2012 or old devices there have never been updated:
