ChinMuzik Posted October 22, 2016 Report Share Posted October 22, 2016 (edited) I just completed the construction for the CS of my MB-6582 build. I succesfully installed MIOS and the LCD is working as it should. After installing the current limiting resistors...when powering on the unit..I get a strange pattern on the matrix. Column 6 of the matrix flashes steady and no matter what I do it won't stop. Also, a couple of the controls LED's pulse very dimly in the same pattern as the matrix column. Several buttons do not work. There is also no response from any of the encoders. And another strange thing, the LCD will freeze and time a "poly" patch is selected. EDIT: I noticed the LCD freezes only when browsing patches while the matrix is in MATRIX mode...if in METER mode it browses fine. I checked soldering and no bridges and no visible shorts. I reaseated the shift registers and checked 5v supply on all sockets which is good. Cleaned all residue on the bottom of the board. After reseating, now some buttons behave strangely (along with ones that didn't work before) Edited October 22, 2016 by ChinMuzik Quote Link to comment Share on other sites More sharing options...
