Issue on DCC900 recording

Hello
I am repairing a DCC900
It reads perfectly well, sound and marker as well as the times.
But when recording, it does not write the markers and the times.
Here are the errors I have on the AUX track:

After i’m recording

Thanks for your help

Hi,
Could be the head and/or the read write board.
Have you checked multiple tapes?

I checked several tapes and I have the same problem
I can’t test with another head/card because I don’t have any others that work
I am waiting another DCC900 to test the head
And i just received 2 CMS VR for R165, because in two cards they are HS
