Hello and thanks for the answer.
The idea with the "cold" solder joint was already not bad.
Leedy (was this) directly in the LED Moule, which is built into the display.
To get to it, I have now disassembled the whole display.
In any case there is an LED def. (the lower one)
The upper one lights up again.
I haven't reassembled the display yet, only soldered in the LED module, because I still have a question.
I can now observe the following when I switch on the machine.
I switch the machine on (plug) the upper LED goes on, the machine does something (I guess grinder) then the red LED goes off after about 4 sec. again.
As said I do not know this machine and now my question would be,
how it behaves directly after switching on.
Is the display two-colored, i.e. in the first eye buzz it is red (the LED works) and then changes to blue (the lower LED is def.)?

Thank you and many greetings
