Raspberry Pi A+ boot problem

Hello,

This sounds like a problem with the SD Card, this usually occurs when it hasn't been imaged properly or becomes corrupt.

If you have another computer with an SD Card reader then you should be able to re-image it?

I have heard of it not getting enough power.  It could also be because of the output settings.  Also try using HDMI as this will work.  Let me know if this helps.

Try to power the Pi without a keyboard and mouse. If nothing happens then try another SD card and i would suggested a 8gb.

Be sure that the power adapter is  5V and 1A and above.

Hi, dtsartsanis. First thing. When you are using the Composite (RCA Connector) Video Output. You may have to hit the number 3 (for PAL) or 4 (for NTSC) on your Keyboard during Boot-up. Each number, (1-4) is used to Activate a Video Output (Composite or HDMI). The default is HDMI, if you don't hit any key, on Boot. After you Boot, one time, with Composite Output. Your Pi, may remember your selection.

Here's the info, from the Raspberry Pi Quick Start Guide...

Your Pi will now boot into NOOBS and should display a list of operating systems that you can

choose to install. If your display remains blank, you should select the correct output mode for your

display by pressing one of the following number keys on your keyboard;

1. HDMI mode this is the default display mode.

2. HDMI safe mode select this mode if you are using the HDMI connector and cannot see

anything on screen when the Pi has booted.

3. Composite PAL mode select either this mode or composite NTSC mode if you are using

the composite RCA video connector

4. Composite NTSC mode

Also, I agree with the other Comments. Make sure your OS on your SD Card is not Corrupted or the File System is Damaged, too. You can do this in any Computer, with a Compatible SD Card Reader. Either Built in or External USB Card Reader. I did end up Re-Formatting the Pi's SD Card with Noobs and then back again with RaspBMC. I had a little problem with the Original File System, that came on the Pre-Formatted Element 14 SD Card, becoming Corrupted. And the System Would Not Boot. I thought at first that this was because. I had to Hard Shut Down the Pi, a couple of times. By Un-Plugging the Power Cord. When I couldn't see the OS in the Monitor. During my Tests on using the Analog TV Card to input the Signal to a Computer. And when the OS Froze up and would Not go to into Shut Down Mode in the GUI. But, Since Reformatting the Card, I have not had this Problem again. Through several Hard Shutdowns, since then. That was a couple of years ago. I have had to Reformat my SD Card twice since then. Initially, I used GParted, a Free and Open Source GUI Partition Managing App, that I have been using since about 2005 to Repair the File System on the Card. I Put the Card in my Laptop and used GParted to Both Repair and Re-Format the SD Card. So, that I would have a new and clean file system.

You may also want to try out, BerryBoot v2.0 - bootloader / universal operating system installer. I ran RaspBMC (XBMC Media Player for the Pi) on my Pi Model B. With 512MB of Ram. From 2013, till 2015. But, after all of the Updates. The System Slowed down to a crawl. And couldn't play most Videos. So, I went in search of a lighter weight OS for my Pi, a couple of months ago. I ended up using Berry Boot to install OpenELEC. Another XBMC Remix, that is very light weight and uses less resources. It is working much better now. There are several other OS's that come with BerryBoot, that may be interesting to you too. That may run better on your Model A Pi.

I think the keyboard numbers to press on boot are 3 for PAL, and 4 for NTSC.

Paul, Yep, your right. I found my Quick Start PDF on my Computer and updated my Post. I still haven't found the link to the PDF Download, though... PS... here it is... Download the PDF here, http://www.raspberrypi.org/wp-content/uploads/2012/04/quick-start-guide-v2_1.pdf

Hi, dtsartsanis. First thing. When you are using the Composite (RCA

Connector) Video Output. You may have to hit either 1 or 2 on your

Keyboard during Boot-up. It's been a while, since I setup my Pi with

XBMC Media Player. So, I can't remember which number is for Composite.

But, each number, is used to Activate a Video Output (Composite or

HDMI). The default is HDMI. If you don't hit any key, on Boot. After you

Boot, one time, with Composite Output. Your Pi, may remember your

selection. Also, I agree with the other Comments. Make sure your OS on

your SD Card is not Corrupted or the File System is Damaged, too. You

can do this in any Computer, with a Compatible SD Card Reader. Either

Built in or External USB Card Reader. I did end up Re-Formatting the

Element 14 SD Card, becoming Corrupted. And the System Would Not Boot. I
