Raspberry Pi B+ - No red light - No signal on HDMI

Former Member
Former Member over 11 years ago

Hi,

   I purchased a Raspberry Pi B+ starter kit from Amazon which includes the RPi B+, prototyping kit, 8 GB class 10 microSD card with NOOBS pre-installed, Miniature 802.11n Wi-fi adapter, HDMI to HDMI cable, 5V Power adapter with micro USB cable etc.

I was able to successfully boot and install the RASPIBIAN image and immediately after the installation, TV started showing "No Signal".

 

Red LED is not glowing at all - Does this indicate a problem with the power supply? I verified the power supply using multimeter and it is in the valid range. (4.7 - 5)

 

I see the Green LED glowing continuously - What does this indicate?

 

I tried re-imaging the micro SD card with RASPIBIAN image downloaded from the site and also tried with two different TV's which support HDMI.

 

Can any one please help on how to resolve the issue?

    Thanks for the response. I had a look at the URL earlier and as you have mentioned, the instructions provided doesn't mention that if they are also applicable for B+ device.

    Red power LED does not light, nothing on display

    The power is not properly connected.

    Any how, I will procure a new 5V Power adapter with micro USB and test this again. In the mean time, can you please suggest if there is any alternative to power up the device and see if everything else is alright? This will help me to isolate the problem. Thanks in advance for any help/tips.

     

    Thanks & regards,

    Sriharsha

    This finally turned out to be an issue with the power adapter. After trying various options, figured out the Red power LED should light even for B+. Used a power adapter which comes with a smart phone which isolated the issue to the power adapter supplied by Amazon.

    Thanks Mike for pointing me to the right direction.

     

    For others who are getting into similar issue, please use an adapter with the following configuration,

    750ma Current Output

    5.0V

     

    Thanks & regards,

    Sriharsha
