Users questions:In 2002 purchased NESO Trinitron FD770A17-inch flat-screen monitors, home, color screen, the last two months there, while yellowish, while bluish, or reddish, partial green, let us analyze the reasons, or possible solutions . In addition, according to the user that there are heard ignition coil hairZizi out sound, but I have not heard before use. This is the boot display automatically degaussing is not magnetic question, again thank you all.
Experts answer: This is a display on the CRT circuit failure, resulting in failure due to tube circuit red, blue, green, three guns, there is a variable resistor circuit contactBad, need to take a close look because as with the deflection coil and ignition coil there is no relationship can be ruled out. If their own hands, then the best would be to open the display in the CRT circuit board can see the seat of adjustable resistance, were measured with the multimeter the resistance value of each because it is composed by three-way, three resistor values should beThis is basically the same, there is a different source, it could be trouble. If you do not understand their own best knowledge of electrical repair is better.
