Our Repair Process for the
DSTK155
Our repair process for ABB DSTK155 units begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the reported issue. For units exhibiting ripple voltage or operational instability, we replace all degraded electrolytic capacitors with high-quality, long-life components. Communication failures are resolved by reflashing firmware with verified images and repairing or replacing damaged communication ports. Overheating issues are corrected by removing old thermal paste, applying new high-performance thermal paste to heat-sensitive components, and performing necessary fan maintenance. Intermittent operation is addressed through meticulous board-level rework to repair dry solder joints and thorough cleaning or replacement of corroded connector pins. Power supply failures are resolved through component-level repair, with a focus on replacing faulty PWM controllers and switching MOSFETs, ensuring the unit meets original performance specifications.
