Since all Trinitrons have a steel/iron slot mask that the in-line beams shoot through they have to have a de-gaussing coil. It is only on for a few seconds but without it you will have (dis)coloration of regions of the screen. The coil is in series with a thermistor or like to limit the current to a short time. As the slot mask can be bent in only one plane and is near the glass, the glass has to be thick to support the air pressure on the straight-line surface. That's why they are so heavy. -Ken

Yes. There are degausing circuits built in that are triggered during the powerup sequence.

Purple tint on corners of television screen


It needs degaussed. Turn the TV off for 24 hours and unplug it. Plug it back in and turn it on. If the degaussing coil in the TV hasn't worked buy a cheap degaussing wand off of ebay. 10 second fix. You can also ask the local repair shop to do it. Anything over $5 I would just buy the wand. Keep magnetic objects as well as electronics away from the TV. Vacuum cleaners can also cause this if it's on the floor.

Sony wega 28 inch colours wrong, circle on screen


It sounds that there is some magnet near by TV that is affecting picture tube. Please remove any extra speaker or any thing that has strong magnet inside, unplug TV for 20-30 minutes, replug back in, turn it ON, hope that will solve your TV problem.
Thanks.

Sony trinton 27inch red light blinks 11 times


those LED flashhing codeds are useless. You most likely have a problem in the high voltage circuits. You should bring that one to a local shop as it's very nlikely you can fix it yourself, and the high voltage circuits are dangerous.

TV has color bloches at corners


Assuming this is a tube style TV (not lcd flatscreen) your degausing coil in your TV sounds like it is defective . The Degaussing coil on newer televisions / monitors surrounds the outside edge of the TV and turns on when the TV is fired up. In the old days, their used to be no degaussing coil - when a child would take a magnet to a CRT television, magnetism would remain on the tube and cause discoloration and blotches as you describe (multi-colored blotches) To correct this a technician used to use a degausassing coil and perform a circular pattern on the screen to remove the improper magnetized area. Since the old days, newer tvs have degauss coils built into them, but if they go bad, or always on etc... they can cause the problem you describe.

Television picture colour


This is because you have something emitting an electric magnetic pulse close to the TV. Like a large unshielded speaker or large Battery. First thing you need to do is move anything near the TV away and see if that correct the issue. Next would be to degauss the TV. Unfortunately the TV probably does not have a built in degausser.

A degausser is an electro magnet in a circle. you plug it in and run it around the surface of the TV.

Count the flashes and verify that the model is KV-32FS100. The flash count will indicate the circuit in which the problem was detected.
