Hisense TV maintenance summary Classification method according to the performance type of TV faults TV faults can be divided into static, random, progressive and hidden faults according to the performance types.
The static type will show a static state after a fault occurs. The fault will no longer develop and will not continue to damage other components, such as low sensitivity.
After a random failure occurs, it will sometimes disappear automatically after a while, but it may reappear after a while, such as rows being out of sync, etc.
Once a fault occurs in the progressive type, if the power supply is not cut off immediately, the fault will rapidly expand and damage more components, such as transformer whistling, etc.
Although hidden-danger TVs can work normally, once there is an opportunity, the fault will appear immediately. Continued use may further expand the fault, such as high-voltage ignition.
