40H80 Remote Control Tip for Convergence

<< Back to Service/Designer Menu Page

The service manual describes the convergence procedures which appears to follow that same convention as the previous sets:

The service describes how to turn on/off the guns by pushing specific keys on the remote once the convergence grid is displayed on the screen:  

  • 100 for Red
  • 0 for Green, and
  • Ent for Blue (use Ch Rtn for later models)

100 and 0 appear to do as advertised but some have reported that Ent does not. 

It appears that you can turn on/off the Blue gun via the "Ch Rtn" button.
