Question about Televison & Video
Though it is possible that the tube is defective as you pointed out, may I offer an alternative diagnosis? Most CRT type TVs are driven by three (3) transistors located in a squarish PCB at the very rear of the picture tube. Each transistor is responsible to drive the red, blue and green guns of the CRT. If the green drive transistor is defective, the symptom you have described would also be the result. It is even possible that the transistor is not defective but any of its pins/terminals might have developed a cold solder.
Should this be the case, then the repair would be relatively easy (replace or re-solder as required) and comparatively low cost.
Should you venture a DIY, please be reminded of safety procedures/precautions when working with high voltages. Should you be uncomfortable going this route, perhaps your best bet would be to seek the services of a qualified professional.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.
