My System: Echostar 3000ip, 1m dish |
Hi, Where can I find the circuit diagram of the Echostar 3000IP power supply? I am trying to establish the resistance value of R3 marked on the Printed circuit board. Thanks Rapper | ||

My System: Echostar 3000ip, 1m dish | Hi Llew, Thank you very much for the value of R3 and the circuit diagrams, most helpful. You mention about checking the PCB for burns, was there any particular reason? The resister is very close to the board on one side and as a result of the heat the solder joint has suffered and no longer sound, but no other damage is apparent. Thanks Rapper | ||

Baking of the board area around it can also affect other components adjacent to it. The resistor often keeps its value but loses its identification marks, as you have found. When replacing, use extended lead lengths to keep the resistor proud of the board. Llew Llew
