Hello For every standard televisions, there will have a degaussing posistor, to demagnatise the picture tube, each time it is switched ON. If thie degaussing posistor has damaged, there will be no degaussing action and color patches on screen will be the relsult. Moreover, check whether there is any external speaker boxes have placed near the Tv. The magnetic effect from the magent of the speaker can also cause this. Posistors sre of severel types, and the pictures of some of them are given here.
It sounds like the set has become magnetized. It could possibly be from an external speaker magnet or some other magnetic field (ie. a vacuum motor). It could also be a malfunction in the built in demagnetizer circuit. Color picture tubes are very sensitive to magnetism. Because of this there is a built in demagnetizer circuit. If this circuit malfunctions it can cause the same problem. Turn the set off and unplug it for 30 minutes or so. This will allow the circuit to cool off and reset. Turn the set back on and see if it returns to normal. Also, dropping the set or a heavy jar can warp the shadow mask inside the tube causing the same problem. If the unplugging method does not work, have a shop check it for you. Thanks for using fixya.
sounds like the monitor experienced being close to a magnetic field.
if the monitor doesn't have a auto degaussing (demagnatise) function on start up, then try using the degaussing function on the monitor (in the menu somewhere).
if no good, then you can try moving/waving a magnet near the affected area. b careful! slowly wave the magnet from a distance 1st, until you have improvements. too close and it will change the colours further!
you have to remove the back of the phone with a small tri screw driver. underneath the board in a corner there is a flat cable that connects the screens to the board. It came loose. press the flat cabe back into the the board chip. they will lock together. the screens will work.. I just did this with my sons phone.
what you are describing is a degaussing problem. It normally occurs if some Magnetic source has been brought close to your TV. Perhaps you have shifted your TV from part of the room to another? Or to another room? Did you or someone place a magnetic source (Speakers, Tape recorder, Walkie talkie, some toy of your children, etc near or on top of the TV? Just remove it.
And wait for a few days. The problem will get automatically cleared up, as the TV set's Auto Degaussing circuits will clear the color patches.
