Midi input dead on EIIIrack the first 10 minutes

Hi Wizards

My EIIIrack has developed a midi issue. When booting her up the midi input does not respond until after 10 minutes. If I power off and on again shortly after midi input is working.

Previously I've had success cleaning the pcb connector and the ribbon connectors that has to do with the midi input. But is this dirty connectors or an IC that needs to warm up before working?

Have any of you had this problem?

Best regards Brian

Well. Cleaning the PCB and connectors again did the trick. Now I have midi.

Its only 3 month ago I did the same. Strange that I have to do this so often.
