I have followed tutorial and assembled my Zynthian V5.1 box but when I plug in electricity nothing happenes with screen and buttons. Rbpi is on (as shown in the pictures) and I have tried connecting midi keyboards to use Zynthian as PSU - it works.
Please, re-burn the SD-card with a fresh image (lastest stable).
Re-check all connections, verifying orientation, insertion, etc.
Insert the SD-card in the RPi directly to be sure.
Then boot and check the RPI5 LED status. You should see the green LED blinking. If the green LED is solid, then something is not right with your SD-card / image.
If it boots but you see the error screen or nothing at all, connect your zynthian to the network and try to access from the webconf terminal. Then send the output of this command:
Hi @jofemodo, thanks for answering!
I checked my connections for display, control, usb-c and sd card. My LED is now blinking green as shown in the video but still nothing on display.
Did you use Raspberry Pi Imager to write the SD Card? If not I’d suggest it, I and others on this forum have had problems with other programs such as Balena Etcher.
I did use Raspberry Pi Imager, flashed latest stable oram and started Zynthian.
Still no change in display and buttons power. These two little lights powered up, as shown in the image
I again connected it to network and tried cat /root/first_boot.log with totally different result:

Does display/buttons related problem got anything to do with this maybe?
I asked Google: “is raspberry pi camera cable interchangeable with display cable?”
and got:
No, Raspberry Pi camera cables and display (DSI) cables are not interchangeable. They have different pinouts and connector types, and using the wrong cable can damage the Pi or connected devices. The camera cable is designed for MIPI CSI communication, while the display cable is designed for MIPI DSI.
I don’t know, I just noticed in your original post you said that you were using a camera cable instead of a display cable because your kit didn’t come with a display cable, and nobody has replied about that specific point.
so I used rbpi camera cable)
