General Information · Repair Cautions

IBM 5154 EGA Display.

Known Issues

The caps in the power supply are knows to go bad, this includes all the electrolytics and rifa caps.

Symptom or Problem Encountered

The symptoms can vary from not powering up to image issues on the CRT. The RIFA caps are knows to explode and release a ton of smoke.

Causes

Leaking and aging capacitors, possibly caused by them being cooked over the life of the monitor.

Solutions

Replace the caps.

Disassembly Notes

  • This is a CRT, so you will need to know how to work around high voltages that could be deadly.
  • The screw covers on the top of the monitor can be fragile and can break, so they need to be removed carefully. The power supply cage can be completely removed and unplugged, but you will need to drill out the rivets to get it open and inversely will need some small screws or a rivet gun to put it back together.
  • There is a slight different list of capacitors for the 110V and the 220V versions of this display, so make sure you are looking at the correct list of caps.
