Blank Screen after Noobs Installation

Mon Dec 23, 2013 4:35 pm

Hi There,

How’s it going? I just got my Raspberry Pi board delivered a week ago. I had this ordered locally along with a clear case and a power adapter.

Eager to get started I bought a keyboard and mouse, SD memory card (16GB) and HDMI to VGA converter.

Reason being my monitor doesn’t have a HDMI slot. I have formatted and installed Noobs 1.3 on the card.

So I go ahead and connect the network cable and start up the board. Nothing appears on the screen until I press option 2.

Then I see the familiar OS options screen and install Raspbian as default.

Install goes smoothly till I see the install completed message.

When I reboot all I see is a black screen. Any ideas on what to do next? Appreciate some advise.

Thanks

From what you've posted above I suspect that your issue may be related to one that exists for composite video (see later). Although I've recently acquired a HDMI to VGA converter ( http://www.cpmspectrepi.webspace.virgin ... erter.html ) myself I've not (yet) tested it with NOOBS 1.3.2 . It's possible that some of these devices need a NOOBS 1.3.2 installation to be performed with "HDMI safe mode" (video mode '2') made "permanent" to ensure that an installed O.S. uses a HDMI setting that is still compatible with the VGA monitor. (In the same way that composite video, modes '3' or '4', needs it to be done thus: http://www.cpmspectrepi.webspace.virgin ... ellow.html). Once everything is working in that (low resolution) mode then, using NOOBS built-in, recovery mode, editor, the O.S's "config.txt" may be edited to obtain a higher, VGA-compatible resolution. NB: you should be using NOOBS 1.3.2 (not 1.3).
Trev.
Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Hi Trevor,

My Bad, what I meant to say was I did download the NOOBS 1.3.2 version from this site. Despite this after the install I did not see anything on the screen. I was under the assumption that the installer would complete and reboot right away.

I Used the offline and network install version on my SD card. How and when should I edit the config.txt file for the monitor to work properly? I checked out the article link you provided. Let me try once again and see how it goes.

I will keep you posted. :)

Thanks & Regards,
Vinod Shankar

Hi Trevor,

I managed to get this fixed from my end. When I first powered up the pi I held the shift key down. Then I selected option 1.
The screen then flickered to life, so now I think I was using the wrong option. It should have been 1 NOT 2.

Well believe it or not I was able to make the following changes to my config file from recovery mode.

If you would like to know what HDMI to VGA+Audio adapter model I used, it was AHDMIAV-01 http://www.avf.com.my/avf.php?c=1&p=532

hdmi_drive=2
hdmi_group=2
hdmi_mode=16


I then saved it and voila its working perfectly now! Next up getting my wireless USB adapter to work!

Model: Prolink WN2001 Wireless N Nano USB adapter http://www.prolink2u.com/new/products/index.php?cid=289

Thank You for your time!

Merry Christmas and Happy New Year!

Vinod :)

To get WiFi running shutdown, plug in your dongle and reboot. There's no hotplugging support in the hardware.

Your dongle may just work (plus or minus needing a WiFi password for your network).

Easiest way to do the config for that is with the GUI. Less easy way is by editing /etc/wpa_supplicant/wpa_supplicant.conf and /etc/network/interfaces.

Search on here there's lots of threads.

If the dongle doesn't work post the output from lsusb.
