Once met mpc3500 with "black out" control panel, replace the control panel no cure & resort to replace the PSU from working machine no cure as well. Fix back the PSU back to working machine, what the hell the working machine pop out a same problem , control panel all "black out", is it this virus spreading scenario?
Finally found out that SC202 generated by using torch light on the control panel u could see. Replace LD unit & BCU, nothing happened again, the both machines resort to be scrap at last.
Any ideas pro why this could happen?
