chinapp:
is it means fix the cut trace can make the mV option  on ? :popcorn: :popcorn:

TiN:
Making meter "detect" mV option will not magically add missing components, no?  :-//

chinapp:
seems no more info on this ............ :scared:

meandeev:
Hello,
was there somebody in and removed some components?!
Attached you can find a photo of the mV-option of my 4920 and also the 400978-2.5 firmware of this device (Sticker says 2.5, inside the firmware you can find the number 2.05)

chinapp:
thanks so much for your pic

it seems not a big problem, could you give a view of the five  transistors? can not get the model of them,and also the foil resistor beside the fuse
