Known Issues

Symptom or Problem Encountered

Causes

  • Power Supply is Faulty with bad capacitors.
  • When you try to power up your MDD, you will typically get a quick power light and fan spin and it will shut off.

Solutions

  • Recapping the entire power supply generally fixes the problem. Although there is a chance some other components are faulty.

Disassembly Notes

Please be careful when opening the power supply because there are high voltage capacitors inside which can cause great injury to yourself. There are 5 screws holding the housing together and 4 screws holding the fans that need to be removed. Once the screws are removed, the top part of the housing needs to slide away from the fans. After that disconnect the fan cables. There are 4 screws holding the board in place, one in each corner. The board can then slide out of place and you will need to flip the board over and desolder the two power cables (blue and brown, please take a picture of where these are located before desoldering them to help with reassembly). After that the board should be completely free.
