This set was dead. IC 601 DP704C in power supply was burst. After replacing this IC, montior shows faint horizontal lines along with display. These lines are somewhat like we see when the monitor is in interlace mode. Is this due to filtering problem?
U can search problem in vertical section may be sum IC component was dry resold them .
