POS Terminal Electronics Repair
A point-of-sale terminal that stops working can halt a transaction line. Sinsal diagnoses and repairs the electronics inside POS terminals at the component level, rather than treating every fault as a reason to replace the terminal.

Equipment Covered
- POS terminal main boards
- Card-reader interface electronics
- Battery and charging circuitry
- Receipt-printer control boards
Common Faults
- Terminal fails to power on or resets repeatedly
- Card reader stops responding while the rest of the unit works normally
- Battery no longer holds a usable charge in portable units
- Physical damage to ports and connectors from daily handling
Diagnostic Process

- Card-reader and interface electronics inspection
- Battery and charging-circuit testing for portable units

Common Questions
Does repair affect PCI compliance or payment certification?
Sinsal repairs the underlying electronics hardware only — compliance and certification status should be confirmed with the terminal provider after any hardware work.
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.
