Known Model Issues

Look up your model on this wiki and elsewhere to see if there are any common issues specific to your models. Some model families may have shared issues or technical bulletins to address them.

Model family issues:

Power Issues

  • Check fuse
  • Check solder joints of AC plug
  • Check voltages on board

Vertical Deflection Collapse

Characteristic red/green/blue retrace lines visible on the screen.

Tube Rejuvenation

Last resort to bring back dim tubes, burns oxidation off of guns.


Internal Magnetic Interference

A CRT can be exposed to enough magnetic interference that the image retains a persistent color or geometry issue. Generally, these issues can be fixed by enough degaussings by the built-in degausser or by using a stronger external degausser coil. While rare, it's possible that internal components or the case shell can cause magnetism issues on the screen.

IK Shutdown Issues

See the pages on the Trinitron IK Circuit.
