#1 Projektor Vivitek DX813, fan error ?

Witam
Projektor pierwotnie przyszedł do mnie z zatartym jednym wentylatorem.
Po wymianie i zrobieniu konserwacji ruszył i wydany do klienta.
Po pewnym czasie wrócił z informacją że nadal się wyłącza.
Projektor faktycznie się wyłącza po 70-80 sekundach i zgłasza losowo błąd FAN1 lub FAN2 lub FAN3.
Wszystkie wentylatory wymienione i kręcą się stabilnie.
Sprawdzałem oscyloskopem sygnały tacho na wentylatorach i wszędzie ma około 90HZ, stabilnie.
Odłączyłem wszystkie zasilania wentylatorów i podałem z zewnątrz zasilanie z zasilacza laboratoryjnego, nie zależnie od ustawionej prędkości obrotów efekt zawsze ten sam, czyli wyłączenie po 70 sekundach i losowy błąd któregoś z wentylatorów.
Co można jeszcze sprawdzić ?
