Black screen via HDMI since today

Help and Support Raspberry Pi
1

Hi there,

I´m using the raspberry pi 2 together with osmc since a while and it works pretty fine with my setup:

Device: Raspberry Pi 2 B
Installation media: microSD
Connection: wired
Power Supply Type: universal USB micro power supply (white)
Power specs: 5V 2000mA
Peripherals: TV Sony Bravia
Storage Device (incl. Network Sharing Protocol):
OSMC version: 2016.07-1
XBMC version: Kodi (16.1). Platform: Linux ARM (Thumb) 32-bit
Audio/Video Output: HDMI
Overclocked: No
Config.txt Extras: hdmi_force_hotplug=1 but tried all other options

Problem: No HDMI signal - or better, no image on the TV. I only have a black screen.
I do can log in via SSH.
I changed the HDMI port on the TV.
I checked the HDMI port of the TV with another device.
I checked the cable by using it between PC and monitor.
I connected the raspberry to my monitor.
I changed the power supply to one with 1.8A.
I formated the sd card to noobs and after that to osmc install image.

Back to my osmc backup I checked tvservice again:

osmc@Raspi:~$ tvservice -n
device_name=SNY-SONY_TV
osmc@Raspi:~$ tvservice -s

Summary:
OSMC is recognizing the TV but the screen stays black.

Any ideas?

Please provide grab-logs -A

Have you shut everything down and only booted the pi after the TV has completely booted and been set to the appropriate input for the pi?

Thanks for the reply.

I shut everything down and put on again first the TV and setup HDMI 1, where the Pi is connected. Started the Pi, which booted (ssh available) but still black screen.

Here the logfile: http://paste.osmc.io/gebilipalo
I stripped some information from the emby addon :slight_smile:

4 
sudo apt-get update && sudo apt-get dist-upgrade && sudo reboot

to get on current stable version and report back please.

Ok update done:

osmc@Raspi:~$ grep VERSION_ID /etc/os-release
VERSION_ID="2016.08-1"

Still black screen :frowning:

Try this

http://kodi.wiki/view/Raspberry_Pi_FAQ#TV_is_not_detected_unless_powered_on_first

7

Did you try move kodi userdata temporarily?

8

Renaming the .kodi-folder doesn´t showed success.

The same with using the edid.dat. Can I check whether the edid.dat is working or not?

So did you had an image on the TV while you had Noobs installed?
Did you had OSMC displayed while doing the install of OSMC or did you just reimage your previous running OSMC install?

May try to install vncserver and see if Kodi is running correctly and it is really a HDMI problem.

There were no image at all on the TV screen during install of noobs nor OSMC.

I will give it a try to install a vnc server. But I assume Kodi is running correctly since I see it online through the remote app.

In the end it seems to be a hardware failure :frowning:

You should have written that before. That either means your Pi is broken, the cable is playing up or all your devices got the flu.
