All LEDs are lit lan ports. Replacement chip lan problem not solved. The chip was heated and a new hot. In the chain of Q601 was found a short circuit, 1 V is not there, but if you remove the throttle voltage appears. Transistor is not broken. Even when Ian chip shot 1 V. not lift ...
Who does that tell me?
Все светодиоды лан портов горят. Замена лан чипа проблему не решила. Чип грелся и новый греется. В цепочке Q601 обнаружилось короткое замыкание, 1 В. там нет, но если снять дросель напряжение появляется. Транзистор не пробит. Даже когда лан чип снят 1 В. не подымается...
Кто что подскажет?
