Digital receivers and receivers have two parts: power and image. If the digital receiver does not turn on, we check the first part. Capacitors can be replaced with the same microfarad value but with a higher voltage. For testing ICs and regulators, the datasheet can be found on the internet and the connection of the power pins and the related pins, etc. is specified. Diodes, which are responsible for rectifying current and converting AC voltage to DC, can also be removed from the board and a connection test (beep) is taken. Resistors can be measured on the board in resistance mode. Hello, welcome to your channel ElecSHow. In this channel, you can watch interesting tutorials on electronics every week.
