: Check the SR360 or similar Schottky diodes on the secondary side. If the receiver is completely dead, these are likely shorted.

: Protects against interference and converts AC to DC.

If you are measuring the output pins, you should see approximately: : Powers the processor and memory. 5V : Logic circuits and USB (if applicable). 12V : Audio and switching. 22V / 30V : LNB power (tuner voltage).

: The most frequent issue. Even if they aren't bulging, capacitors like the

The power supply block (PSU) generally follows this architecture:

For a detailed visual guide and component labeling, you can refer to technical repair forums like Remont-Aud.net or Tele-Satinfo , which host specific circuit diagrams for the .

The satellite receiver (part of the General Satellite family) typically uses a pulse-width modulation (PWM) power supply, often based on the DM0265R or DM0365R chip. These units are known for common failure points due to heat and aging. Common Schematic Block Components

: Usually 33–47µF / 400V; a common culprit for failure if it bulges.
