Known Issues

Smoke when plugged in

Causes

  • Leaking C5 capacitor shorting resistors?
  • C5 on Power Supply board leaking

    C5 on Power Supply board leaking

  • Resistors on bottom side of PCB under C5 didn't fair well

    Resistors on bottom side of PCB under C5 didn't fair well

Solutions

  • Clean and recap, possibly replace parts on bottom

Recommended Preventive Maintenance

Cause

  • The T1600 contains two internal rechargeable batteries that may begin to leak and cause corrosive damage to PCBs
  • E1 is a through hold mounted 3 cell battery on the mainboard that wasn't yet leaking in my example but could possibly.

    E1 is a through hold mounted 3 cell battery on the mainboard that wasn't yet leaking in my example but could possibly.

  • 4 cell battery connected with cable had corrosion through the entire copper wire and white power beginning to leak from the shrink seal.
