Sziasztok !
A tárgybeli gép sormeghajtó jele helyett csak az alábbi remegő 32khz-es jel jön ki a prociból. A készülék egyébként 50 Hz-es. (005kép). Néha próbál szélesedni, formálódni, olyankor már kezd négyszögre hasonlítani és felülről közelít a 15625 Hz-hez, de leginkább ez a rángatózás látható, ami nem elég a meghajtáshoz, folyamatosan leülteti a meghajtó tranyót.

A Hout-ra kapcsolódó felhúzóellenállás, a soros 100 ohm , a jelformáló 1nF ok.Tápok rendben megvannak.
Ha a sormeghajtó bázisára külső jelet adok akkor elindul a gép, nagyfesz, képcsőfűtés rendben, van fény.
A sorvégfok rendben megy, így:(006 kép)
A proci TDA 9351PS/N3/3/1997.A kvarc rezeg, SDA,SCL dolgozik, készülék bekapcsol.
Találkozott-e valaki ezzel a jelenséggel?
