The source monitor

A project log for LCD light box conversion

A quick "afternoon" project with a scrap monitor.

This project started when a suitable monitor was found in a scrap bin. In this case, an HP LA2405x LED backlit 24" monitor. It was labeled "bad". Powering it up confirms that the actual display wouldn't drive from a computer source, or even the on screen display. However, the backlight worked, which made it a perfect one to use.

If the backlight didn't work, I could still have used it, but it would have been harder to figure out the backlight LED drive specifications.

But my experience disassembling LCDs shows that all sorts of surprises can be found which makes the unit harder to use. Need to take it apart to find out.
