Check vertical output circuits. They control the up and down deflection and when not working you get straight line across front of tube.

Three coloured lines appered on the screen - no picture


If there is no picture and 3 vertical lines in the center of the screen, stop. Turn off TV. You have no horizontal deflection happening. Lines will burn into crts and be permanently visible after repair.

No horizontal deflection is caused by Horizontal sweep circuit failure, maybe flyback transformer and associated components. More than a simple do-it-yourself repair.

Clearly shows problem in deflection area both horizontal and vertical section. Horizontal lines is due to vertical section problem and making bbzzzz is due to horizontal output transistor short and sometimes LOT SHORT.
