Hello 3rd Island, thank you so much for sharing all this knowledge, it saved me so much time already! I was wondering if you knew anything about a X-28 not rewinding? All other functions works, when i press Rewind, it starts 1sec and then literally switches off, screens test all position. Like a false contact? I took it all apart, plugged it, the tape rewind fine when the module in my hands, other boards like the mixing board taken off.
@@3rdisland477 Hello, thank you for taking so quickly your time for answering. I think it does turn on. Just quickly and then switches off. I just tried more things, as I said it seems to work some times (the REW). It did again and i found out that while plugging (P604) the red socket (it carries +5V, -5V, GND as well as Mute) to the mixer board. So Not sure how but the mixer board might have a dead component? a short circuit of a kind, thought I find it strange that it only appears with REW. Getting closer to the problem...
