  • In addition, there can be IK blanking. A weak CRT, intermittent shorts in the CRT elements, improper G2 cutoff, or intermittent components can cause the issue.
  • Verify the G2 cutoff and try turning up the screen/G2 slightly.

  • Remove the two screws and disconnect the lamp connector running into the ballast 
  • Slide out the bad ballast and insert a new replacement ballast.
  • Seal off the TV again after tightening up the equipment.
