Classification method according to the performance type of TV faults. TV faults can be divided into static, random, progressive and hidden faults according to their 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.
