No go VU8C

Unread postby Seedywee » Sun Jul 22, 2018 8:58 pm

I have two complete VU8C + C2 kits no more than a week old. Everything's working except for one of the displays, which remains black.
Swapping this display from one case to the other indicates that the display itself is faulty. Even with high magnification, I can see no damage to the ribbon cables.
I'm hoping that this display hasn't died. Are there any further checks that I can make?
Thanks!

Please swap the HDMI bridge boards and other internal cables to narrow down root causes.

How is the LCD backlight?

Do you fix like this?
116 # Enable backlight_pwm
117 # disable : backlight "no"
118 # ODROID-VU5/7 : backlight "yes"
119 # ODROID-VU8 : backlight "invert"
120 setenv backlight_pwm "invert"

Thank you, odroid and codewalker for your replies.
I advise that swapping the HDMI bridge board and internal cables has definitely pinpointed the display as being the problem. The ribbon cables are undamaged. It looks difficult to remove the display from its plastic bezel. Could anything be learned from that?
Codewalker - your help is appreciated but, as a newbie, I can''t figure out your input. Could you please expand a little? I'm using Android but could easily change to Ubuntu Mate.
Thanks!

Insert your eMMC or SD card to Desktop PC.
and you can find boot.ini file from Storage.
Edit boot.ini like over that.
