Remove purple haze around edges


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.

Need to fix the color and screen


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

I have a Samsung CRT slimfit that I bought in 2006. It has worked splendidly until about 4 months ago and suddenly I have started to notice the edges of the screen about 2-3 inches on both sides have...


In my experience from doing Samsung's warranty work on slimfit sets, they have issues with picture tubes causing problems on the circuit boards. Many times I would replace a board only to have it fail a short time later. The wide crt draws a large amount of current and many have purity (discoloration around edges) problems. I would suggest you try contacting samsung to see if any recall exhists on these and if that doesn't work I wish you luck having it repaired properly for under 275.00
