故障现象:开机图声正常,但图像水平向右移动5cm,屏幕上整幅图像显示的只有2/3。分析与检修:图声正常说明机内主要电路工作正常,疑点应集中在附加电路上。将此故障机与正常相同型号机子相比较,发现故障机在图像水平偏移的情况下,还伴随着图像质量(鲜锐度)差一截。据此分析,如果是偏转线圈调整不良,在其他电路工作正常情况下,其图像效果不应较差,又根据大屏幕彩电所特有的电
Symptom: boot sound is normal, but the image moves horizontally to the right 5cm, the entire image on the screen shows only 2/3. Analysis and Overhaul: The normal sound of the figure shows that the main circuit in the machine is working normally. The doubt should be concentrated on the additional circuit. This fault machine with the same type of machine compared to the normal and found that the fault plane in the case of horizontal image offset, but also with the image quality (freshness) difference of a section. Based on this analysis, if the deflection coil adjustment is poor, the normal operation of other circuits, the image should not be poor, but also according to the large-screen TV-specific power
