Hi
I have 2 CS2 (60215) and have had some issues with one of them. It was not booting completely.
The display would turn on with the start image and then the progress bar, instead of stopping at the middle and displaying the arrow on the screen center, would just continue filling the progress bar til the end and nothing else.

I opened the unit and could not see any damages



This seems to happen regularly on older CS2 (mine is a 60215 mother board installed by Märklin in 2014 to repair a 60214 of 2012.

My take is that during the boot (cold-start process), a flash memory is altered alas to update / rewrite the memory you need tools I don't have.

In my case, I tried to reboot a very large number of times until the unit would start completely when this happens, BEFOREHAND I had prepared a USB memory with the latest update and it forced writing on the memory. Then I did an on-line update. Since then my CS2 is starting every time (touch wood).
Why this method? On-line update will see that your unit is already up-to-date and will stop the process so you have to start with a USB update which goes all the way.
I have 2 60061 (60W) and one 60101 (100 W) and I can see that it has no influence whatsoever on the CS2.

Why do I have two 60061? Because one of them failed me but later I realized that it was just a bad connection (Broken wire) in the DC plug that connects to the CS2
The 2 60061 have a DC voltage of 19.6V while the 60101 has a 19.4 V
This is just my opinion but I am an Engineer with experience in analog and digital electronics and micro computers.
Cheers

I doubt it, the 60215 has a completely different PCB to the 60214.

New PSU arrived and same issue persist. So CS2 seems to be the rootcause. Maybe it is something related to display as it seems to boot but display does not come on.
