@Jim253 As far as I know Square unfortunately doesn’t offer out of warranty repairs. I don’t think you could repair it yourself or have a 3rd party repair as Square has anti tampering built into their products that will disable them completely.
Square Register, Square Terminal, and Square Readers, are designed with anti-tampering mechanisms to ensure device security, protect payment data, and comply with industry security standards such as PCI DSS (Payment Card Industry Data Security Standard).
