This is hardly off topic.  My own experience with CRTs is that they 
become dimmer and dimmer over time until they are virtually useless. 
The phosphor simply wears out.  Half life seems to be in just two or 
three years.

It seems that some models experience failures in their high-voltage 
power supply.

The high voltage supply is repairable but the CRT is not.
