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?

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"
