"Halo" Effect
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.
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 55 inch Mitsubishi Big Screen Television model #VS-55705. It turns on, but if you turn it off, it takes about an hour before you get a picture or sound. There are vibrating horizontal white lines running continuously on the screen. I sure would appreciate any assistance. Also, does anyone know where I can buy a repair manual for this model? Thanks, very much!
