I builded the “pre built” kit , but screen don’t turn ON (always black, with or without SDcard) i tryed to disconnect 2in1 module but nothing change
What SD image are you using? Is it the last one “Gorgona Next”?
Have you checked that the screen is connected in the right position? Note that you could connect the screen reversed …
Have you tried to connect an HDMI display to the RBPi connector? Can you describe what you see? A photo would be nice …
sorry for the delay, i solved my problem with a new ribbon cable
Have you built your own ribbon cable? Can you send a photo?
Anyway, i would like to refund you for the broken ribbon, so please, if you could send me the broken ribbon for analyzing, i will refund you the cost of this part. As we aren’t hurry, you can send it inside an envelope, as a standard postcard for cheaper shipping.
First post here, I am gathering parts to build my own Zynthian, and happened to notice the ribbon cable is the same type/configuration as an old legacy PC IDE HDD cable.
Theoretically if you can find a dual drive IDE cable, it should do the job.
I made a simple building documentation here: http://wiki.zynthian.org/index.php/Build_a_Zynthian#Alternative_cabling
It does the job…
I had the same problem with ribbon cable a few times already. They are very delicate as is seems.
