The aircraft both in AV or TV status, the lower grating curling, the upper horizontal bright line appears, and the field amplitude jitter up. Field measurements of each foot voltage output block TDA3653B are dithering, where {8} pin voltage jitter between 1V ~ 5V, TDA8361 related field oscillation part {41} {42} {43} pin voltage is also in jitter. Failure to distinguish between the presence of the oscillations or field output stage, off-field signal input resistor R301 (horizontal bright line to prevent screen burn, vice
