Solution: Try to add an AV signal to the AV terminal. Automatically searched for the station and found that the TV program flashed past and the program number did not change. It was estimated that the sync head did not pass in the CPU. When auto-scheduled, the CPU 36 pin voltage is not changed, and the waveform measured by the oscilloscope is very small. It is detected that the NV01 (TA8851BN) 46-pin waveform is normal, indicating that the fault is between the NV01 (TA8851BN) 46 pin and the NA01 (TMP87PM36N) 36 pin. On the line. The inspection found VA06 (2SA1015Y) b-electrode capacitance CA13 (2.2μ F / 50V) leakage. Can replace CA13, troubleshooting.
