HDMI module problems

andy869 · Oct 9, 2016

I've tried installing two different modules now in my P4 controller, and I never get the firmware update option. It won't even connect to the drone once installed , unless I pull the back cover off (and disengage the hdmi).

Is there a way to force a controller update?

Did you make sure to install back the three ribbon cables and secured them with the three tiny lockers?

You probably did, but look at this video where the guy doesn't show how to put back the ribbons on the new board. For me this is misleading..

Yeah, I was very careful putting all the ribbons back in. I did it and re-did it multiple times with different modules.

At this point I am getting no communication to the bird, and no options for firmware downloading. Forcing a firmware download I am prompted to select "NONE" for firmware updates.

With the back part of the module off, everything is normal (except hdmi of course)

Pulling off the back of the module, I now can see firmware updates and it connects to the bird, however the only firmware option is a downgrade.

I tried installing the firmware, it just sits and beeps at 0%. Installed my old board and the same thing. Did I just brick my controller? So frustrated, this should be simple and I just wasted 3 hours.

Ok, got my old module back in, everything works.

I just don't get it. I've tried two HDMI modules now and neither work.

Wondering if the HDMI module(s) you got is/are good one, you know this thread right;

Faulty HDMI output module

Maybe HDMI board compatibility issue with RC model GL300-?

You might want ask support to DJI and post results here.
