Здравия!
Иммем 4 таких бука с одинаковыми симптомами...
никаких признаков жизни кроме мигаюсчего желтого светодиода (индикатор подключения к сети) мигает след образом :
4 коротких мига + 5 длинный после 3 коротких ( короткие длительностью приблизительно пол секунды, с интервалом 1 сек, 5-й длительностью около 1 сек)
Все компоненты которые возможно было проверить отдельно - проверены, напряжения на плате в норме, криминала нет, визуально никаких повреждений. Разве что симос батарейка 2,5В, ставил новую - никаких изменений.
Сервис мануала, что бы узнать что етот "миг" значит не нашел, в пользовательском мануале написано вилами по воде...
Вот собссно и вопрос: что значат ети мигания ?
P.S. забыл добавить - ети мигания по кругу, с перерывом ~3 сек.
дежурка бредит? Вкл-выкл, выкл-вкл, вкл-выкл???
тут подсказали что мигания ети значат 10h
так что теперь рзбираюсь что к чему у пациента...
Теперь 3 бука работают у одного другой код мигами...разбираемси.
Другими словами обратите внимание на мигания индикаторов и запишите их в виде:
короткое мигание - К =0 (логическому 0)
длинное мигание - Д=1 (логической 1)
далее, например мои случай:
читаем справа на лево:
00010000 00010000 00010000
00010000 = 10h= AC Adaptor output voltage is more than 16.5 V. итд.
коды смотрим по выдержкам из сервис мануала
необходимо учитывать тот факт что для разных моделей коды будут значить разное, ниже приведенные коды относятса к _данной_ серии буков.
