7 Segment display keep black after boot messages

**valesho** · 04.02.2020, 01:35

Hello again

I'm not sure if it's possible to solve this little issue by this way.
The 7 segment LED display work fine at boot time and while updating by USB.
But after boot and OS load keep black, showing nothing.
See both situation in the attached video:

Just normal boot:

Update by USB Memory Stick:

Also, I think this is related: the set button for power on, stand by. power off is not responding after boot, do nothing when pressed.

Again, thank you.

BR

which skin, try another one, is it the same?

It's same, change nothing.
There are not too much to select by default.
In Menu, Setup, Usage & GUI, STB Display, LCD Skin Setup there are only two option (pictured below).

In the plugin download & install screen, there no Display (I think not necessary, just 7 segment LED bars).

Changing another Enigma 2 skin change nothing in the STB Display.

v6.4 and v6.3 images tested up today 05 Feb.

You are right, those data was missing in the file /usr/share/enigma2/skin.xml
Add the missing data still same. Also replace the concerning data, but nothing too.
File /usr/share/enigma2/display/skin_display.xml is there and correspond to github code.
So, I guess it's something else.

Attached is zip file with original and modified and tested files.

could be missing support for the display driver, which is you display device, I have 7 segment display too, can you check this in telnet

Code:

root@h7:~# dir /dev/dbox/oled0
crw-rw----    1 root     root       10,  57 Jan  1  1970 /dev/dbox/oled0
root@h7:~#
root@h7:~# echo 9999 > /dev/dbox/oled0
root@h7:~# echo hallo > /dev/dbox/oled0
root@h7:~#

my display can show only channel numbers and clock, can´t write text, depends all on Hardware

Try this skin_display.xml for 7Segment ...

Code:

\usr\share\enigma2\display

**valesho** · 05.02.2020, 18:01

Regarding "missing support for the display driver", issued the command as below

Code:

root@turing:~# ls -l /dev/dbox/oled0
crw-rw----    1 root     root       10,  52 Feb  3 01:43 /dev/dbox/oled0
root@turing:~# echo 9999 > /dev/dbox/oled0
root@turing:~# echo hallo > /dev/dbox/oled0
root@turing:~# ls -l /dev/dbox/
crw-rw----    1 root     root       10,  52 Feb  5 14:40 oled0
root@turing:~#  echo 9 > /dev/dbox/oled0
root@turing:~#

Do nothing in the display, show nothing, change nothing.

Tested skin_display.xml file from @HD75hd replacing original one, changed nothing.

Maybe a driver issued, not a missing driver, I think so. And it's related to set power button issue too.

Thank you
