Since retirement from an industrial electronics, technical field, and after a lifetime in the electronics field, But with a wish to still keep my electronics skills "alive" (or mebe it is the brain) I began to repair monitors and computers saved from a fate worse than death (LandFill).

I donate repaired PC's and monitors to local church groups for them to give to "New Australians".

The majority of monitors (and some motherboards) mostly suffer from the same faults, they can and often do fail earlier than three or more years old.
The frequent cause of failure is overheating and secondly frequent power voltage surges from the mains supply.
