Мои познания в ремонте данного вида техники: Любитель Наличие схемы: Нету Марка и модель - Dexp 43UHG1 Процесор - MT9602LAATIB Модуль обработки сигнала (Main) - TD.MT9602.761 Блок питания (PSU) - MP80TL-2P32-JB1 LCD матрица - PT430GT01-8 Прочее (T-CON, инвертор...) - Tcon N4THK500UHDGT02-1
Телевизору чуть больше года. Да, он гарантийный. Был. Пока хозяин не сорвал пломбу и не полез посмотреть. Поэтому вопрос с гарантией закрыт, не начавшись. Предистория- завис на логотипе или во время загрузки, Хозяин путается в объяснениях. Ко мне попал с ребутом на логе декспа. Проверил все диф пары, ничего пробитого нету. По питаниям чисто, без пульсаций. Флэшка KLM8G1GETF-B041. Снял её, слил прошивку, вот лог если интересно

Здоровье флэшки отменное, запись-чтение без ошибок. Единственная доступная прошивка здесь в обменнике от 55UHG2, залил её. Теперь логотип пролетает, появляется лого Google Tv, висит на нем минуту и ребутится. Вот терминальный лог в это время

Какого-то криминала не заметил. Проц умеренно теплый. Есть заведомо новые флэшки, но не думаю, что здесь дело в ней. На кнопки Vol-\PWR не реагирует. Сейчас постоянно автостарт происходит и ребуты каждую минуту. Попробовать написать производителю можно, конечно, но хозяин может не дождаться. Могу выложить слитую прошивку если это нужно. Либо просто жду советов.
