Power Supply Repair
Power supply boards are one of the most common failure points in electronic equipment — and often one of the most repairable at component level.
Common Equipment or Faults
- No output voltage
- Output voltage out of specification
- Unit trips or shuts down under load
- Visible capacitor damage (bulging or leaking)
What Sinsal Assesses
- Input and output voltages under load
- Condition of capacitors and switching components
- Whether the fault originates on the power board or downstream
What You May Receive
Diagnostic findings, Repair record, Post-repair verification result.
Important Limitation
Some power supply failures damage downstream components too, which affects overall repairability.
Frequently Asked Questions
Common Questions
What are the signs of power supply board failure?
No output, incorrect output voltage, unexpected shutdowns, unusual heat, or visibly bulging or leaking capacitors.
Can a power supply be repaired rather than replaced?
Frequently — capacitor and switching-component failures are common and often repairable at component level.
Have Equipment That Needs a Second Opinion?
Describe the equipment and the fault. Sinsal will confirm whether it's a fit for diagnostics and repair before any work begins.
