[SOLVED] VU8C black screen

Unread postby Seedywee » Sat Jul 14, 2018 4:59 pm

A newbie to C2 and VU8C, I have just received two of each, running Android OS. Both have a black screen. I've already checked out other posts on this subject.

Both of these units work OK with a separate HDMI monitor. On the VU8C displays, the bright light of the backlight can be seen peeping through slits around the edges of the display but the screen remains black.

The ribbon cables seem to be undamaged and seated properly. I have reflashed one with Android Marshmallow 4.3. No joy so far - help would be appreciated. :)

Can you edit boot.ini file to configure the HDMI output mode manually?

It is also worth to try to connect a PC HDMI output to VU8C HDMI input to narrow down root causes.

Thank you for your time - both ideas sound good.
The HDMI idea's a bit hard as I'd need a gender changer, weeks away from this small island through eBay.
Re the boot.ini idea - I'm using an eMMC card. I can't see boot.ini inside the Odroid, so do I look for it in the eMMC using my Transcend card reader on my Linux box?

Try another way.
Connect your C2 to a working HDMI monitor.
And run "ODROID-Utility" app and select "1024x768" resolution in Screen setting menu.
Then, shut down the system and connect the C2 to your Vu8C.

Brilliant! Many thanks! Actually, the resolution selection, "ODROID-VU8" worked for me.
