The set needs to be focussed and reconverged. The red and blue images combined make a magenta/purple image. Adding green makes it white. Depending on the type of TV, if it's a CRT projection TV then there's an electronic focus control for each of the three tubes as well as the mechanical adjustment of the optical lenses. Given the description, then I'd have a look at the electronic focus first. A sudden shift in focus suggests that something in that circuit has given out. This would cause the red and blue images to go soft enough to create a halo around objects on screen.
Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.
The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as www.TvRepairKits.comto get a repair kit with instructions.
Usually this is bad fluid in the blue and green CRTs. the tell-tale sign is that the blue will just haze, look at a guy in a black suit.. you will see the blue just hazing out around his white shirt and tie. This is common for all these philips TVs and is dirty cooling fluid in the blue and green CRTs. A repair shop will charge you about $300 for the fix, maybe less if you're lucky. You could fix yourself for about $40 and some time, but would need to have some mechanical skill and some free time on your hands. Let me know if you need further assistance.
The coolant in the chambers that are part of the CRTs(picture tubes) has been contaminated by foreign matter and the high temps created by the CRTs. The coolant can be replaced but its an expensive and time consuming operation. Some of the parts needed for this repair may also be no longer available. I'd start shopping.
The green dot in the center sounds like a burn mark on one or more of the picture tubes inside the set, and the curved lines are telling me that you have a problem in the convergence circuits. The blue haze around everything white tells me you either have a lot of dust build up on the lens over the CRTs, or your picture tube(s) are very weak. If this set is over about 12 years old, I would replace it. I doubt if you will be able to get the green dot out of the picture without changing the tubes which would be VERY expensive.
