Question about Sanyo HT30744 TV
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.

I too had the same problem where my HT30744 TV would lose its color. My mom's HT32744 would have the same problem too. They both are refurbished models bought at Value City Dept store. If I gave the cabinet a good hit it would mostly fix the color, but it could also make the picture go fuzzy too, a clear sign of just a loose connection somewhere.
So after my wife telling me she was sick of this almost 2 year problem and she was going to buy a new TV on the weekend, I figured I had nothing to lose. So I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.

Open it up (remove the 8 or 10 screws) and clean the dust (by compressed air or vacuum cleaner hose) off the circuit board. It fixed mine like a charm! A dust buildup creates a short across the closely spaced circuits and disrupts your picture. You may need to do this every few years, especially in dusty environments. Works for computer motherboards and power supplies too! You have nothing to lose, and it's very easy. Just be gentle with the circuit board.
