Troubleshooting:

1. For the first reason, the user first moves the magnetic objects (such as speakers, etc.) away from the color TV at least one meter, turns off the power supply of the color TV (the main power supply on the color TV must be turned off, and cannot be turned off remotely). Turn on the power supply of the color TV after 4 or 5 minutes. If the color spots are not completely eliminated, you can repeat this step. If it cannot be eliminated after repeated several times, it means that the picture tube is too magnetized, so a special color TV degausser must be used to degausse the picture tube
