Raspberry Pi Forums

Hello,


I have just got my brand new Raspberry B+. However, I get no signal on my hdmi monitor and i'm not sure if it's powered on.

my equipment used:
Raspberry B+
Kingston 16GB SDHC Class10 micro SD card
5V-2A Power adapter : http://www.hn-electronic.de/?products=h ... tt&lang=en
and a keyboard: Cherry MX-Board 3.0 USB

I tried the following:

downloading the Raspbian Image, extracting the zip and writing the image directly to the sdcard using dd (/dev/mmcbk0, IIRC). Mounted the partitions afterwards was possible.
Plug everything into the Pi. Keyboard, HDMI, SDcard.
switch my monitor to hdmi input (yes, my monitor works on hdmi)
plug in the micro USB power connector.
Nothing happens. No image, no LED on the PI or on my keyboard is on.

I tried the following:
Verified the Socket is powered.
Tested with my phone charger (5V, 0,7A) Samung
still nothing

unplugged hdmi and keyboard
plugged in ethernet cable (yes, its connected to my router and the port is working)
plugged in power
-> no power led on PI or ethernet port
couldn't find the device on my router's management software...

Prepared Noobs Image:
download latest NOOBS zip
deleted partitions from sdcard with parted, and created one (whole disk) with fat32
mounted sd-card partition
extracted NOOBS zip to sdcard using unzip
using sync and umount

Configuration:
monitor, keyboard, sdcard, power
-> nothing happens
tried the same steps with a old 2GB micro SD card
-> still nothing

Is there anything I can try or should I send it right back to the retailer?

If you're not even getting the red power LED turning on, then either your PSU is seriously underpowered (do you have another one you could borrow to try?), or your Pi is faulty and should be sent back.

as stated: tested with 2A, 0,7A and now with 1,2A power adaptor.

Nothing. Does the B+ even have a powerLED? I can't see anything that could qualify

Yup, the small surface-mount PWR LED at the top-left corner.

ah, i guess you have to see them glowing to notice them

well, i guess this PI needs to be replaced

thanks for the help

If nothing connected but the power supply to the micro USB and no LED on the RPi lights up?

1 usb cable is broken
2 power supply is broken
3 RPI is broken

Since you switched the power already it has be 2 or 3.

Can you measure the power pin on the RPi?
