Заголовок сообщения:  philips 42pfl6877t/60 не запускается, мигает 2 раза.

Добрый день форумчане. После недавно воскрешенного саундбара от Филов, приехал и телек 42pfl6877t/60. Говорят раньше через раз включался, теперь совсем тишина. Вскрытие показало, что пациент таки пытается включиться, дежурка у него стабильно 3.3V, 12V линии поднимаются и держатся, телек делает несколько попыток запуска (6-8), керамический радиатор греется, не более 50гр, рука терпит, затем остановка и начинает мигать 2 раза с перерывом. Проц остывает.
К блоку питания вопросы закончились, перешел к main. Напряжения то же поднимаются и ничего кроме проца не греется.
Основные замеры проводил на конденсаторах, по ходу дела буду дополнять, может потомкам пригодится.
2uv7 - 1.2V
2j3k 1.5V
2j27 1.5v
2ja3 3.3v
50c2 1.1V
2upg 1.5V
При попытке подключения через UART видны только прерывания на перезапуск <0>
Так же основательно потекла термопрокладка, плата была обмазана с 2х сторон, включая 7j04, 7j03, 7kc0. Может это и послужило виной, нужно разобраться. Кто может, знает прошу помочь в этом деле.

Посмотрел ссылки, все сводится к прогреву проца и улучшению охлаждения. Это можно попробовать, но после перепрошивки. Лог 2 содержит ошибки при загрузке, по этому имеет смысл начать с флешки.

В этом был явный смысл?
Если бы было все так просто

то никаких проблем с ремонтом данных модулей не было бы. Подводных камней тут намного больше, чем кажется.

Аккуратно чистить компаунд, реболлить проц и восстанавливать дороги под компаундом. Причем дороги восстанавливать между лакированным текстолитом и точкой прикосновения компаунда. Они там рвутся. Все делать крайне аккуратно и под хорошим микроскопом
