You can buy a Tricolor power supply for this receiver here https://www.wildberries.ru/catalog/41...
Tricolor no signal
In this video I will show how, in the absence of a signal, the master consistently searches for a malfunction. In this case, after opening the receiver, it turned out that water got into the receiver through the cable and the incoming circuit burned out.
Repair of this receiver is possible, but the client decided to buy a new one.
