Can you repair a CRT?

Repairing a CRT monitor allows you to continue to use the same tried-and-true system you have been using with your equipment. A CRT monitor is not as efficient as an LCD screen, but it can still provide a reliable display for your systems.

Are any CRTs still made?

Absolutely. CRT material and process technologies are common to the vacuum tube industry as a whole, which continues to serve many applications across a wide variety of industries.

How does CRT rejuvenation work?

The other method of rejuvenating tubes is the procedure which is usually termed “reactivation”. The result of this procedure is that a new supply of emitting oxides are formed on the surface of the cathode, and the tube should then be good for a further period of use under its normal working conditions.

What is in a CRT tube?
