How can I fix it so my RCA F35317 tube TV picture/graphics is not blurry?

Graphics is OK but not the picture... this suggest a fault prior to the RGB drivers or video switching stage.

Ideally you need to 'scope' the video signal along it's path with an oscilloscope.... since the poor picture is not caused by the tube or it's focusing otherwise the graphics would also suffer the same effect.


It may well be a common 'stock fault' with this particular model.

Adjust the focus control on the back of the flyback someone bumped.
