Hi all, I have an issue with the line6 m13. All effects work but the lcds are either blank or black boxes. (LCD colour backgrounds still work) It seems a pretty common issue when looking online, but there doesn’t seem to be any solutions.
Has anyone had experience with this or any thoughts on what to try. Service manual is available online.
Thanks
