Heya! I have a Porta02 mkII and all 4 channels playback as they should, and the input on channel 2 works fine. Channel 1, however, is dead - no input audio (on 1 or 3), no LED response. I cannot find anything visually the matter on either PCB, and the connecting cables all look intact. Where should I focus my attention to narrow down the fault finding?
Thank you!
Thank you!
