Screen Crab : Solid Cyan - no capture

[Floater]

Hi

Got my Screen crab and after following the instructions gets stuck on solid cyan status without capturing any screenshots to microSD. I am not using the wifi/C2 version just local on the micro SD

I have tried different resolutions on 1080 1920x1080 and lower

And even changed the capture interval from 5 to 20

Would appreciate your help

My config:

LED ON

CAPTURE_MODE IMAGE

CAPTURE_INTERVAL 20

STORAGE FILL

BUTTON EJECT

DEBUG_LOG ON

 

And captured the log:

Are you feeding the signal into a monitor, a TV, or something else?

[Skinny]

Just to follow this up, usually this behavior will occur if you have the HDMI input and output switched on the crab.

[Aaron Outhier]

This occurs on one of my systems also. It still occurs if I reverse the HTMI cables on the Crab. The funny thing is, the video displays perfectly on monitor, but C2 says the crab is waiting for a signal. The problem seems to go away if I use a different monitor. Oddly enough, the TV I was using that has the issue also gives me problems on my Raspberry Pi 4 - The Pi never detects a device on that HDMI interface, and nothing is displayed on the TV. At least with the Crab, I can use the TV.

 

On a semi-related note: My TV doesn't receive the HDMI Audio signal when the Crab is in the mix, but works fine when I remove the Crab from the equation. I'm not sure if this is normal - the Crab might not be designed to relay HDMI audio.

BTW, the issues I have occur on a TV, when I use a Dell Monitor, I have no issues. I also use a DVI to HDMI for the monitor, since the monitor doesn't have speakers, and I my video card has only one HDMI and one DVI.

That's the issue. Do not use any adapters
