Raspberry doesn't start anymore

[erosweij]

The rasphberry doesnt start ánymore.
If I start the raspberry only the red PWR led is on, but the raspberry doesn't start.
I think my powercable works well if I charge a mobile phone.
Does annyone has a solution for me how I can fix it?

in general, it is almost never the Raspberry PI thats suddenly defective, (except when it blew its polyfuse or if you damaged its card holder). in general its mostly the SD card that somehow became unbootable, or it is the power supply that Is suddenly not delivering the power it should, but see the polyfuse remark as a (partial) cause of that.

SD-cards can become unbootable because files were corrupted during shutdown, because power was removed while the SD-card was doing maintenance tasks, or because the flash memory got worn out because of too many write cycles.

What was the last thing you did?
If you put the SD card in another computer, is it recognized okay? Any corruption? What size, class, and brand is it?

Hi,
I have a 10 class SD card and a 4 class SD card both 8 gb.
They are running well in pc and photocamera.
Sometimes the ACT led will turn green shortly when I turn on my raspberry.
Pleeeeeeease don't tell it's broke...

I had a simular problem.
For a couple weeks it would suddenly reboot after 10-30min.
Then it started rebooting after about 5secs.
Then it would not boot at all, and the status LEDs where off.
It turned out the usb pwr supply was weakening.
My cell phone still worked fine off it.

So I bought a power adapter cable and connected to a heavy duty 2A wallwart - it started working!
