32" sony crt (2007) Good picture but slight yellow color upper right corner and slight blue color upper left corner
The problem is the discoloration of the picture this happens due to magnet effect..or a magnet probably speakers set of a sound system place near your tv..2nd is the built in demagnetizer of your tv is malfunctioning...the built in demagnetizer is place at the back of the pictire tube it is wrap with an electrical tape and place around the picture tube..it is activated everytime the tv is power on...the demagnitizer is controlled by a thermistor switch..it is a device which is activated by a certain temperature,once it reach the max temp.it switch off..check whether it is soldered proerly on the pcb..use a soldering iron to fix it..you can also buy a demagnitizer from an electronic shops to demagnitized the picture tube..simply plug in the demagnitizer to an AC outlet and with the TV powers on bring the demagnitizer in front of the tv in front ot the monitor press the switch on button and move the demagnitizer in circle and sideways until color is ok..caution do not power the demagnitizer for a long time this produces hit rapiddly.
