Raspberry Pi does not turn on

Wed Sep 25, 2013 1:44 pm

Alright, I have had my raspberry pie for about....6 months now and its frustrating that the thing will not run. Here is my setup:

Raspberry Pi model B
32" LG tv with HDMI input
1A micro-B USB power supply
Dell keyboard and mouse (both confirmed compatible on the wiki)
A 16gb SD card with Rasbian on it.

Alright so when I plug in the power, only one red LED comes on, thats it. It used to be, at my other place (before I knew python), that when I plugged it in, the red LED would come on along with a couple others such as the ACT, and I could see some nice output on the screen.

Is there something I am missing?

It could simply be that the TV is not switching to the hdmi input when there's no signal on it (Pi is switched off)
Try switching on the Pi first then selecting the hdmi channel on the TV

start again from scratch
burn a new image from the downloads page
plug it into the TV
then Network
switch TV on
then Power it up.

what happens
don't bother with mouse or keyboard yet

If you're not seeing even a brief flash of the green ACT LED then it's possible that the SD card is no longer making "proper contact" in its socket and/or the card socket has broken - check for something this: http://www.cpmspectrepi.webspace.virgin ... ilure.html

Thanks for the responses guys!

Aw lame! I just checked my SD card, it looks chipped on top left corner near the contacts when looking at it from the bottom. I guess I'll have to get a new card w/ a new image.

Alright so I got my new SD card and flashed a new copy.
I also bought a new supply, a 2A one that goes into the wall.

The PI boots up and I can even see the desktop for a while, although I still have the issue that it just randomly turns off.

Any ideas?

OK, sounds like its working normally. BTW, if you're using wireless, you'll only see the red and green LEDs.

With no keyboard/mouse activity, the idle-time-out limit will occur, and the screen will "turn off" while in the x-window. Pressing a key will turn the screen back on, bring it out of screen saver mode.

But...its not working correctly....
I'll be working on the thing and it'll just shut off...
Keyboard and mouse are for sure being used.

Maybe it's a "marginal" HDMI signal level issue? Does the screen "just blank out" or (eventually) report "No signal" or similar?
It might be worth checking some of the options discussed here:
http://elinux.org/R-Pi_Troubleshooting# ... VI_monitor
(eg. the "config_hdmi_boost" setting, perhaps?)

Is it just the monitor that goes off, or the Pi itself?
You could test if the Pi is still alive by trying to ping it from another machine.
Enter this at the command prompt or terminal, obviously change the IP address to be the IP of the Pi.

Code: Select all

ping 192.168.X.X
If the Pi replies to the pings then its something to do with the monitor, if not then the Pi has died.
Can you try this and report back?

I don't think it is an HDMI issue because all of the LEDs turn off except for the red PWR one. Although, I don't remember if there is a "No Signal" on the screen so I will try again and let you know.

I am pretty sure it is the PI itself. After it stops, I get no response and when I try to re-ssh back in, it times out. But I will try your suggestion nonetheless.

I am pretty much open to any fix right now. I've been trying to figure this out since March 23rd of this year so what is that...almost 7 months.

Alright so picking up where we left off, the raspberry pi just shuts off and the video is reporting a "no video signal"
any ideas?

To give some more information as to what was going on, I had just clicked "save" to save a file that I'd named BOM.py

I did some searching around.
My model is the adafruit BS1238

It looks like some problems have been noted. I'll verify the measurements later tonight, but I'm just curious if anybody has had an issue with these
