The control knob of this Philips BD563A broke because the previous owner didn’t notice or care that the knob was turning heavily and so after a while it broke out.
Since it is basically impossible to get the right colour AND type of knob, one has to come up with something. Printing a new button is not an option, since I do not own a printer and part of the knob is in plain view.
So I fabricated a sliding axle and have affixed part one of the control mechanism onto it. No glue, just a precise cut and some thinking it over many times.
Only recently it got patched because it apparently puked out the root password. Secondly, Roundcube is horribly outdated and not easily to upgrade. It also still has the white-space bug, preventing you from logging in.
If you finally fixed the bug and managed to log in, you can’t send any email. It’s supposed to run out of the box and it only does it partially. The interface is easy and once it works, it does the thing. But generally, it’s poorly maintained.
