So, B4R head, working. Moved downstairs, set back up, not working. It was not dropped, shaken, beaten or called dirty names (until it quit, that is). Upon visual inspection (under the top plate) the caps, board and all associated pieces appear as one would expect. The fuse and power switch also passed initial consideration. So, before 1) removing the board, committing my boyfriend and myself to a project that currently holds no discernible direction, goal or end; or 2) finding a local shop to hire that may or may not know how to repair the head; I thought I'd reach out here first. Any thoughts? Of note: yes, the cord and outlets have been factored out as a potential source of the problem. All snarkiness is directed at a particular B4R, your input, thoughts and ideas are most welcomed! -Snark!
