Tried dump from remont aud and my tv turned on upside down and channel swap enabled. Attached is original dump, read from defective memory and written to new memory. Device worked correctly. See photos attached for panel type, model etc.
Был в ремонте телевизор Centek CT-8128 со сгоревшим блоком питания. Вместо шим 7536 установил OB2273. Прошивку для вас считал и выкладываю. На EPROM название BH1643 25Q64CSIG. Определилась как Gigadevice 25Q64. Фото платы прилагаю.
