Actually man... you need to find the flyback transformer for the green tube, and adjust the raster on the green screen down a notch. most likely you are dealing with an issue where the coil inside the flyback transformer to your green CRT has a bad spot on it and the coil wiper is setting on top of it causing the resistance value to drop on the overall coil. Find the flyback transformer for the green CRT, adjust the screen coil slowly until the lines fade away. Do not adjust the focus coil. Screen coil is usaully above the focus coil.

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck

SOURCE: Convergence issue?
This still could be the convergence . This will should be repaired by a tech if you do not know how to repair . Around $200 - $300 if you could get it to him or more if he has to make a service call . Call around for the best price as alot of shops vary in there charges. On this problem if it is the convergence make sure they will use the original IC's and not the cheap replacements as they do not hold up as long . Good luck

This set is fairly easy to fix for this trouble. A AV48p30 usually takes me about 40 minutes to fix for this problem.
It uses two of the STK-392-110 convergence chips. The repair involves two things--getting at the chips (easy) and being able to unsolder them and replace them.
You can buy almost everything you will need on Ebay for under 30 dollars (I can tell you who to look for there)
Most shops are going to get 300 or more for this kind of repair so if you or someone you know can do it you can save a lot of money.
I can tell you how to get at the chips and also everything you will need to do the repair.

Tips for a great answer:
Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.

Could you show a picture of the distended cover you mentioned?
Were the light blue lines you were referring to, diagonal, or truly horizontal?
