Saving monitors: leaky capacitors
A common issue with electronics are when small insignificant components fail. Fixes then usually only depend on 1) Knowledge/problem solving and 2) 1-2 $/€/£ in replacements.
In this case a very common issue, leaky electrolytic capacitors. While most parts in a computer monitor should be fine for a couple decades these little parts can start to leak their electrolytic fluid or dry up and thus loose their capacitance. As their job is to store electricity, this usually lead to wierd issues. Happily Its usually very easy to diagnose. Here the tops of the parts was bulging, a clear indication.
Switching them out and no more issues and these old screens can continue living a happy life another ten or so years.
Don’t discard what can be easily fixed and given another life, there are always someone you know for whom such a thing is an upgrade. Even if you have decided to change out the old, consider giving your old things to charity or help someone out, no need to increase the landfill. (and fixing what’s broken can be a good in itself)
