This is a CRT (or picture tube) projection TV . and if the green CRT won't come on it doesn't mean the crt is bad. The red or ble CRT could be put in the place of the green one to confirm if the tube is bad . It is more likely that the voltages feeding the green crt (middle CRT) are bad or missing. In either case it takes a bit of troubleshooting and disassembly to confirm. A CRT costs between $200-$500.

Hello:

Yes is is your convergence IC's. One has gone bad, but consider replacing both of them because if one has gone bad then the other is not far behind. They are located on the middle board of your set. They are mounted on a large heatsink, the part # should be STK-392-040. Replace these and your set will work fine again.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
