The tv screen has gone pink. no other clor, just pink.

do other I/O ports work? May have defective I/O PCB

screen drive on back of the screen has gone. they do over heat. the pink is the plasma lighting. replace the screen driver board and should be fine, when replacing put a bit of heat sinc on the top of the 2 or so chips big square ones on the board should help it last longer.

If using a box for signal disconnect it from power for a while to see if when it reboots this issue is gone or not.

could be a colot wheel gone bad or stuck

no there will be apart called as ptc,
it may be gone or having loose contact ,,,its dosent cost much

You need to degauss the CRT, there is a built in degaussing coil but its needs more power . this is simply magnetizm that needs to be removed . see if you can before a coil somewhere.gd lk

hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners?
If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened.
