перепутал ± у передатчика (по глупости паял в 2часа ночи)
питание подавалось секунд 5.
Теперь он не работает, не греется и от него идет тихий высокий писк.
Я немного шарю в микроконтроллерах, но вот такие аналоговые схемы для меня тайна.
Подскажите что смотреть кто разбирается. Крышку снял, с виду все нормально…
Может кто в питере чинит за денюжку?
извиняюсь, нашел такую тему, можно закрывать. но вопрос с ремонтом в питере остается открытым!)
