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 done something like that but i plugged mine out for like a day still had it so i left it for like 2 weeks and couple days then it went away then on that same day i noticed it started coming back and second time so i locked of the tv and went 2 sleep.Next day its back 2 dark shadowy middle and i was told by a friends dad sometimes if u have the brightness of the tv up over 50 or 60 % that can damage or have a magnet round the tv and if u did have 1 round it get it back and in a circle shape move it round anti clockwise and that should fix it . Hope i helped.

How can I fix My Sony Bravia 55" LED TV that has a dark area on the Screen


Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
