Display won't turn on but HDMI out works

The display doesn’t turn on for even a second. Previous threads said that flashing a new image on the SD solves the issue, but no luck after two flashes with balenaEtcher (the image is http://dl.clockworkpi.com/uConsole_CM4_v0.1b_xfce_64bit.img.7z from the github).

The 4G module is disconnected to rule that out. My unit is a “uConsole Kit RPI-CM4 Lite” kit so I shouldn’t have a CM4 with a eMMC.

I’ve unplugged/plugged in the ribbon cable several times now. It’s fully seated as far as I can tell and the latch is shut.

Any suggestions? I’m new to Linux and Pi’s so I bought the uConsole to gain some exposure. Just hoping to do that without being tied to a monitor or TV all the time!

Hey, I ran into the same problem with my uConsole Kit. In my case, it was a dodgy ribbon cable connection. I had to unplug and replug it a few times, making sure it was perfectly aligned and securely latched. Also, I found that swapping out the SD card with a new one solved it for me. You might want to double-check your power supply too, just to be sure it’s giving enough power.

The power supply I’m using is 5 volts 2 amps.

No luck with the new SD card and a couple more tries at messing with the ribbon cable.

How long has the device been on? You may have to look into logs or check if the display is detected. I have a strong feeling you need a replacement. E-mail Clockwork for help.

I’ve left the device on up to 15 minutes and still no luck. Where can I check the log files?

I can see the display is detected in the display settings. Disabling and reenabling it didn’t fixed it.

e-mail alex you need a new one. alex@clockworkpi.com

Hey Bob I’m looking at your pi module and the clip on the left looks fine but the one on the right doesn’t look like it is clipped in place

Try pushing it down until you hear it click I had the same problem during assembly and had to put pressure on that side as well.

Tried that and no luck.

I sent an email to Alex about the display. Fingers crossed I can get a quick replacement

Sorry it didn’t work I’m sure Alex will send a replacement I’ve seen others get replacements.
