Zamieść wyraźne zdjęcie SWOJEJ płyty w obszarze urwanego pada. Zdjęcie musi być wystarczająco ostre, aby były widoczne ścieżki.

Clean the flux residues from the location of this transistor with IPA and attach a clear photo of the area of this transistor with visible copper traces on the board.

Ta ścieżka prowadzi do tranzystora Q813 pin1 (bramka) obok złącza COM1.
