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. http://tv-remont-spb.ru/files/Philips_QFU2.1E_LA.rar - SM https://yadi.sk/i/ch99Kos6Q9reXQ - фото платы
