Google for the service manual, should be available online for free, the G2 voltage should come from the D board where the high voltage circuit is.

This TV is horrible. I have the same one and not even a year replaced the light bulb twice. Very disappointing for a Samsung.

From your description it sounds like G2 voltage on the green picture tube is too high.
Are you confident about adjusting it yourself? There are high voltages in places which can kill. I will not take any responsibility of you getting an electric shock so I suggest calling in a qualified TV technician.

Any TV technician should be able adjust this voltage and it should not take long to do it unless the cases are hard to remove and hard to access the flyback transformer where the G2 (screen) adjustment is located.

Otherwise it may be a faulty green picture tube and this is expensive as you need to get the tube replaced.

Hope this helps

In my case, the adjustment was available from outside the TV. Sortof. On the rear of the TVabout 2 inches to the right of the coax in, there are two vertical slits on a little protrusion. Inside the slits are the two adjustment screws. The lower screw adjusts brightness, the upper screw adjusts focus. I spend 30 minutes popping the case apart just to find that I could not access the adjustment screws from inside. Lo and behold, they made them easily accessible from the outside. On a side note, I have never seen a TV designed as poorly as this on the inside. You have to literally reach in and unplug things just to get the back off. All the electronics save the tube itself are mounted to the rear chassis. On all other TV's I've seen (taken apart, rather), all the electronics are in the FRONT part of the chassis so that they move WITH the tube.
