Analog CRT video displays are based on the same principles as vacuum tubes - the cathode ray tube is a vacuum tube. Of course it will behave the same way, wear out and eventually need replacement the same way, need a warm up period the same way, change it's characterisitcs over time the same way, need calibration, and be influenced by external magnetic fields effecting it's electron guns - hence the need for degaussing. LCD and DLP displays work on completely different principles. If they wear, the mechanism is completely different than anything based on vacuum tube technologies.

Just because different objects are "electronic" in nature, this dose not mean that they will behave the same way and have the same needs for things like calbration. A video display (especially a CRT based one) is not the same thing as a preamplifier like the 950 by a long shot. They work on completely different principles. In addition, you cannot directly compare two different objects in regards to the same parameter - it's like comparing the wear charactistics of your car with the space shuttle. When was the last time you had your cell phone "calibrated"? Has you computer shown any signs of improvement by "breaking in"?

All electronics things cannot be lumped into a single category any more than all mechanical things can. The needs, operating principles, and wear characteristics of each device within a category can be completely different.
