A short, practical follow-up to and : white-screen failures on the Dell E193 family are usually an internal hardware issue. The reply from points in the right direction; the checklist below provides additional, non-overlapping ways to isolate which internal piece has failed and whether a DIY repair is realistic.

Quick isolation checklist

  1. Swap source and cable — test the monitor with a known-good PC and a different video lead (try every connector the monitor has).
  2. Try the built-in menu/buttons — if the on-screen menu appears, the panel and its illumination are responding and the problem is in the pixel-data/timing side; if nothing appears, the monitor’s electronics that drive the panel are more suspect.
  3. Note the front LED behaviour (steady vs flashing) and any unusual sounds on power-up — these are useful clues when matching parts or looking up service notes.
  4. Photograph labels and board stickers before opening the cabinet; then, with the unit unplugged and documented, reseat any visible flat flex cables and connectors (don’t cut traces or force connectors).

Repair paths and parts guidance

  • The small timing board and the thin panel-to-electronics cable are common, inexpensive replacements; their part numbers are printed on the boards or stickers inside the rear cover.
  • Panel replacement is usually not economical for low-end 19" monitors; replacing the small board or cable is a cheaper first attempt.
  • Buy parts that match the printed part numbers, not just the monitor model.

Safety and practical notes

  • Always disconnect mains, use anti-static precautions, and avoid touching high-voltage illumination parts in older models.
  • Document every connector, take clear photos, and compare board P/Ns before purchasing parts.
  • If the cost of parts and time approaches that of a good used replacement, replacement is the sensible option.

The fault: A lack of video signal reaching the LCD. The video signal is being recieved, but it is not being transferred to the LCD Panel. your backilights are fine, hence the white screen. I have nevefr repaired one of these, but my first action in this case, would be to inspect very closely all solder points on the logic board and the power board. Stay away from the inverter board and the control board and the laminated boards that attach to the LCD. They are working fine here. Dell is known for weak solder points. Use a 5X or stronger lense to inspect, and be very discriminating. Make sure your lighting is either Nonntime bright or as close to it as possible. Second, check for burn marks, burned composnents or melted components. Good luck.
