Abnormal display
• The method of maintain single source (such as TV, AV etc) abnormal display: Firstly, check the relative channel circuit's
component whether have obviously short and virtual jointing. It is need to use forehead method to deal with the covert reason.
It is need to check Tuner's outputs for TV source abnormal display. Because of Main IC's high degree of integration, all of the
video signals are transmitted to the back end after processed by main IC. All of the sources’ abnormal display may caused by the
main IC's abnormal run. So it is need to judge the problem is caused by the main IC or fore-end circuits. You can do like this: Put
the good machine's TV/AV signal into the bad machine's Main IC ,and put the bad machine's TV/AV signal into the good
machine's Main IC. If the problem follows the action, the problem is caused by fore-end circuits. If the problem not follows the
action, the problem is caused by the Main IC or the periphery circuits.
