Сегодня хотел бы поделится опытом работы с сервисной документацией или как ее еще называют “Сервис Мануалами” (Service Manual) мобильных телефонов фирмы Samsung. Многие мастера недолюбливают именно эту фирма за малое количество принципиальных схем на новые модели телефонов. Но зато сервис мануалы довольно быстро появляются на просторах интернета, только в них довольно скудно описаны неисправности, которые можно и самому отремонтировать да еще в большинстве своем построены по шаблону и не отражают особенностей каждой модели. А вот что самое неприятное, так это отсутствие номиналов установленных элементов что в большинстве случаев полезнее чем шаблонный алгоритм проведения ремонта.
Хотел бы поделится с Вами способом определения маркировки элемента по “Перечню деталей” (Parts list) прилагаемому практически к каждому сервис мануалу.
Power-on password hp compaq 6715s manual guide on 2c.eohaber.site.
Возьмем к примеру Сервис Мануал к телефону Samsung GT-S8500 , на 14-ой странице которого начинается перечень установленных элементов, т.е. Parts list.
Question: Q: How to disassemble Power Mac G5 (Late 2005)?? I have found out my power supply is bad on my Power Mac. I have another power supply and have worked on these systems before but the older model. So, I am officially crazy. I bought 26 Powermacs (G5) And I modded them ALL They are now ready for ATX and mATX Mainboards But why 26? Did I mention I was crazy?! (And they were only sold.
Предположим что по воли судьбы к вам на ремонт пришел телефон после удара или после попадания влаги, клиент жаждет его восстановить и вы приступили к работе, но вот незадача после сильного удара оторвалась от платы какая-то микросхема, допустим U604и естественно хозяин телефоне не нашел ее на полу куда уронил телефон или найдя ее не задумывался что кусочек “пластика”, размером 3 на 3 мм., может быть микросхемой его любимого телефона. Вот теперь нашей первоочередной задачей будет определить, что же за деталь стояла под маркировкой U604? Это хорошо если у Вас на текущий момент в ремонте находится точно такой-же аппарат или донор и Вы со спокойной душей можете посмотреть ее маркировку или даже снять ее.
А что делать если неоткуда снять и негде смотреть, вот тут на помощь придет Сервис Мануал. Открываем его не 14-ой странице и ищем наш элемент U604, в описании написано что это IC-SENSOR – микросхема датчик, ну это уже что-то. Теперь смотрим номер в графе SEC CODE –1209-001817 это и есть зашифрованная маркировка элемента.
Вот чтобы расшифровать этот SEC CODEмы перейдем на сайт www.samsungonderdelen.com и в любой из полей поиска введем наш код 1209-001817.
В ответ на запрос получим интересующую нас информацию, в нашем случае, отсутствующий элемент – Акселерометр BMA023 фирмы Bosch в корпусе LGA с 12-ю выводами, размером 3 на 3 мм. и в пластиковом исполнении.
Теперь нам будет намного проще найти аналог этой микросхемы или заказывать ее у поставщиков запчастей. Или найти схему ее подключения и по маленьким кусочкам собрать нужную нам картину.

Какую информацию можно найти в сервис мануале (инструкции)
Сервис мануал (инструкция) содержит в себе информацию, относящуюся к обслуживанию и мелкому ремонту того или иного оборудования. Как правило, Вы получаете сервис мануал для Вашего устройства при его покупке. Кроме того, на сегодняшний день существует множество Интернет ресурсов, предоставляющих инструкции для устройств различных моделей и марок.
Что такое схемы?
Схемы и схематические диаграммы являются неотъемлемой частью электротехнической промышленности, так как они представляют собой наглядное описание конструкций тех или иных устройств. Схемы необходимы для обслуживания и ремонта различного оборудования и электромеханических систем.
Использование руководств (инструкций) по ремонту.
Руководства (инструкции) по ремонту для того или иного устройства обычно выпускаются независимыми издательствами, не имеющими отношения к официальным производителям оборудования. Это не те инструкции, которые изначально поставляются вместе с приобретаемой техникой. Хотя в целом информация, содержащаяся в руководствах по ремонту, схожа с той, которую можно найти в обычной инструкции, между данными документами есть явные различия. Дело в том, что руководства по ремонту обеспечивают нас более детальной, полной и специфичной информацией.
