Мои познания в ремонте данного вида техники: Любитель Наличие схемы: нет Состав аппарата. Марка и модель - HAIER 50 Smart TV HX Шасси (если известно) - CV6886H-A Процессор - MSD6886N LCD матрица - CC495PU1L.4K (DH1VL1D4901PAL622769)
Текст сообщения: Здравствуйте, прошу помочь сменить тип панели .
Предыстория: аппарат попал ко мне с мертвой emms, в новую KLM8G1GETF залил через колодку RT809h ПО от 50 Smart TV BX (так как на 50 Smart TV HX не нашел), почему то не сразу все пошло но теперь ТВ смог подхватить ПО по USB. - Через USB заливаю ПО от сюда >>monitor<< и хотя панель указана такая же - изо раздвоено. - Через USB заливаю ПО от сюда >>remont-aud<< изображение вродебы норм но поскольку модель другая не работает кнопки на ТВ
Возвращаю ПО взятое с монитор.нет, подключаюсь по UART и за неимением опыта собственно не понимаю что далее делать , панель менял по uart только пару раз и на реалтек. Команда panel в этом шасси (возможно во всех MStar ) не работает.
