Default Marshall MG100HDFX ,2002

Loss of clean channel intermittently, dirty channel ok.
Both clean switches have no contacts made in clean mode.
I'll replace the clean vol control, but nothing obviously wrong. No
obvious solder problems in that area.
Anyone know if anything of the clean ch,separately, goes through the
digital effects pcb.? 3 pcb fixings only on 3 of 4 corners, allowing one
corner to lift with vibration, the header side. I'll reset pins and fit
a cable tie over that corner (too populated to have a 4th fixing)
When I can repower I'll remove the dsp board and see what that does
