mongrol Posted March 4, 2017 Report Share Posted March 4, 2017 So it wouldn't be a change of season without Mongrol breaking something. I got sick of the Orange case and its sneaky ways of making me always write circus music and I replaced my SEQv4 into a black case. On the way I've broken all the buttons on M3. What's the traditional way of troubleshooting a matrix channel? (I'm specifically asking instead of working it out myself to get it recording on the forum for others.) So far I've identified the buttons not working. Looking in the MBSEQ_HW.v4 file I can see the following # SR Pin BUTTON_STOP M3 5 BUTTON_REW M3 4 BUTTON_PAR_LAYER_C M3 6 BUTTON_GP11 M3 0 BUTTON_GP12 M3 1 BUTTON_TRACK_SEL M3 3 BUTTON_UTILITY M3 2 Which are exactly my broken buttons. What next? Quote Link to comment Share on other sites More sharing options...
latigid on Posted March 4, 2017 Report Share Posted March 4, 2017 If it's a row of the matrix, I think the problem is on the sink side. Are LEDs out in the trig buttons, pause and GP 13/14? Quote Link to comment Share on other sites More sharing options...
mongrol Posted March 4, 2017 Author Report Share Posted March 4, 2017 Nope. All those LED's are working. LED's on GP11/12 are broken (along with the buttons). Quote Link to comment Share on other sites More sharing options...
latigid on Posted March 4, 2017 Report Share Posted March 4, 2017 Whoops, wrong row. LEDs out on GP11/12, rewind and stepview? It points to a bad 595 chip (U7) or broken connection somewhere. You might even find reseating the IC helps. Quote Link to comment Share on other sites More sharing options...
mongrol Posted March 5, 2017 Author Report Share Posted March 5, 2017 Replaced U7. No luck. Is there a wiring schematic somewhere other than the Wilba.pdf thats in the shape of the CS? Quote Link to comment Share on other sites More sharing options...
mongrol Posted March 5, 2017 Author Report Share Posted March 5, 2017 Fixed. Cable wasn't in right. Thanks Lat. Quote Link to comment Share on other sites More sharing options...

latigid on Posted March 5, 2017 Report Share Posted March 5, 2017 Maybe an addendum; what was the issue? Still a faulty 595 and a loose cable? Or was the original okay? If anything wasn't plugged in properly I'd think nothing would be working. Quote Link to comment Share on other sites More sharing options...
mongrol Posted March 5, 2017 Author Report Share Posted March 5, 2017 Cable wasn't fully seated into the socket underneath the CS. While it looked like it was in, it was at very slight angle meaning that channel wasn't made. Quote Link to comment Share on other sites More sharing options...
