Matrix what you suggest me please?
Thanks Matrix, can you please share a picture for this special chip/IC and FET / MOSFET transistor on main printed circuit or on PSU.
Many thanks
aaa oki paolino,matrix thanks, the large probability fault is the single tuner of my vu+?
I hope that problem of tuner because tuner change is most easily than electronic diagnostic and electronic change.
conclusion: ca can be everything (PSU,electric component on motherboard) is ok, but the tuner is fault?
Many thanks matrix, i haven't motor equipment, its connected directly to LNB.
i suspect static electricity arrived there via length of cables(long).
there is not overload protection on tuner which block the output tension?
