I would say it's a adjustment you will need, is the convergence aligment ok, to adjust this you will need to find the adjusment block in the front, this is a black unit about 4" x4" and has lot's of wires that comes in.
On this block there will writing on it focus, and screen, well your half way there.
Adjust the green screen control downard to see if it adjuses your green problem if it does, here how you adjust the rest.
First go to your menue, turn the colours off. yes off.
next put contrast to max.
next turn your brighness to 40%
Nest ajust the screen control until you no longer see any trace line of the colour you or seing so that at the end product you het the best black and white picture you can. This will give you the end resolt for best picture posible.
Adjust the other colour after, to see if you or close to the corect adjustment go back to the menu and turn contrast down you shouldn't see any trace line.
Another problem people don't understand this unit have to be clear once's every 2 years.
This I won't explain it's a very long process if done right . Rear projectors has to be clear because with time you will notice the picture looks like you have catarack. or white filtering of the picture. This is when you know it need's cleaning, I do it all the time when I go to customer home, yes I do house call's. I think I'm the last one out there, most shop what's the tv in the shop mostly to be able to control the price there about to hit you with and if the customer doesn't pay there just sale it, they have the control and not you.
I hope this help, keep in mind it's very expensive to have tv repairs, but you have to pay, this what keep's tech going without them, well you can just imagine.

It looks like the convergency ICs failed on your TV. The IC numbers are STK 392-040, they are mounted on a big heatsink.
This may not be a DIY project, so I would suggest to take the TV to a repair shop.

3 things to look at
1 did the bulb burn out
2 did a pet get behind tv and pull the video inputs out
3 is the remote input set for the right video settings to run tv

Thats vertical deflection failure . Check the solder on the vertical output IC and the Yoke plugs. If that doesnt help you may need a new Vertical IC

you should not have to worry about high voltage as long as everything is unplugged. If you are worried leave it unplugged for a few minutes... the service manual warns to discharge the picture tube anode to the CRT conductive coating and wear goggles, but any charge should discharge after just 10-15 sec at the longest.
