​ Проектор Benq MX661. Проектор не включался. Лампу заменили на новую Philips made in China, без модуля, продавец заявлял как оригинал. При включении лампа зажигается, постепенно увеличивая яркость до очень яркого, изображение начинает подрагивать, примерно через 30 сек. лампа гаснет. Загорается индикатор LAMP (красный), POWER и TEMP выключены. Включается вентилятор, через некоторое время проектор выкл. Счетчик лампы сброшен. Хотел осмотреть балласт на проблемные пайки, электролиты. но не могу снять крышку. Все винты открутил, но что то держит в центре у задней стенки, боюсь сломать. в сервисном центре в Мурманске заявили. что лампа не оригинальная, возьмутся за ремонт если у них закажу новую. Подскажите хотя бы как вскрыть.
