An old man brought this satellite receiver to be fixed. It was a dead receiver. Took the cover off and scanned the power board with my naked eye but could not see anything there.
I powered up the receiver and started to test the voltages in the secondary power supply. All the diodes in the secondary section were not getting any kind of voltages whatsoever. That is an indication of a bad primary power supply. I tested the voltages at the main capacitor and I could read the 300 volts there.
