It looks to me a loose solder, or loose contact joint somewhere in the video section or at the CRT board itself. Try also to resolder jungle ic pin, extra care must be observed in soldering this IC, see to it that no voltage is present before doing this,it may damage the ic.
Hope this idea will help.

Green screen


Not really sure how much the tv weighs, but I know it is a bunch. I have 2 of these t.v.s. One I bought at Wal-mart and after about 6 months it started doing this green screen also. I would normally give the side of the tv a good wack and it would go back to normal for awhile. The other tv I bought from my neighbor who was moving for $25. The problem with this one was the "no picture but I have sound". If I wacked this one I could get the picture to come back on for a while, but it would go out again. Well just the other day I took the back off the "no picture" tv and was looking around. I noticed that the circuit board that is attached to the picture tube was loose. I pushed it back down on the tube and put it back together and the picture has been fine since. So I thought I would check the one with "green screen" issues and sure enough that circuit board was loose also. Pushed that one all the way back down and have not had any issues with that tv either. Hopefully that fixed my problem, I guess time will tell. Maybe it will fix yours also.

Picture disappearance & tv turns off


It sure sounds like you have a classic case of bad solder joints. Resolder all the connections on all boards.
