tv - 47PFL6877T/12 SSB - QFU2.1E LA NAND - 29F8G08ABABA Кратко предыстория. Проц ранее был заменен на новый,(хотя тогда причина была в прошивке - зависал), при этом радиатор был поставлен алюминиевый на термопасту. После чего аппарат проработал пол года теперь вовсе не включается. Сейчас - проц прокатывал с флюсом, на паялке БГА. Нанду заменил новой, с той самой прошивкой. Но похоже что вычитываемое из нанды вовсе не стартует. Ошибка 2, в SDM 53. При подаче 220 все вторичные напряжения подымаются, в норме 3.3v, 5v, 1,5v(4 Ом), 1,2v.... На протяжении около 5-и минут 4 раза дергает питание, после включения и каждого дерга на шине данных NAND коротко проскакивают данные около 10мс. При этом на терминал выплевывает почти одно и тоже, что на старом NANDе что на новом вновь записанном... Может кто знает, судя по логу - в чем проблема?

mzr910 писал(а): проверить все vref памяти Проверил. По прозвонке везде по адресной шине около 50 Ом по линиям vref по 500 Ом. Как и должно быть, на сколько я понимаю. При работе - на той паре что 256*8 по всем делителям всех линий стоит среднее - 0,72В. без каких либо шевелений. в том числе и на M1_RESET# 0,72В. похоже эта пара идет под видео, и пока отключена. - на той паре что 128*16 по всем делителям всех линий адреса стоит - 0,31В. без каких либо шевелений, на M0_RESET# = 1,2В. без шевелений на CAS#,RAS#,CKE,CS#,WE# = 1,2В. без шевелений RESET - снятый, но обращения отсутствуют (M0-CS# = 1,2В) Я понимаю что частоты там не шуточные, но если бы был сигнал, то осциллограф(SDS 1072CML+ 70MHz) показал бы хотя-бы среднюю составляющую, на время работы с памятью. Что еще можно посмотреть... ?

То у меня такая погрешность у осциллографа. На разных пределах он вычисляет разные уровни. Перемерял тестером +1V5-ХХ = 1,535В 4 точки DDR-MVREF = 0,767В, 0,769В, 0,760В, 0,773В 2 точки M1(0)-MVREF1(0) = 0,765В, 0,767В Диодная прозвонка оных vref дает M1(0)-MVREF1(0) = 0,279В в сторону проца, и DDR-MVREF = 0,373В в сторону памяти. Думаю по vrefам тут все нормально. А те что 0,3 и 1,2В это 0 и 1 для интерфейса работ с памятью(0<vref<1). Тем более эти уровни стоят на массе линий, а не 1-й двух, что не похоже на неисправность - все 15 линий адреса не могут быть подгнившими строго одинаково в одну сторону, а управляющие сигналы строго одинаково в другую сторону.

Нашел еще одну нерабочую плату (в соседнем сервисе), но с нормальным/полноценным логом. По которому её удалось починить. Лог ниже, где четко указано какую деталь нужно менять. Вложение: 115.7z Старая плата при этом пригодилась на запчасти (НАНД и I2S коммутатор).
