Hi forum friends,
Got this Changhong power supply board model no.715G6503-P03-011-001C to tinker around. It was the power supply board for a defective Philips 200V4Q lcd monitor. The monitor was long gone disposed and i was given this board. The problem is there is no 19vdc output on the connector CN902.
Fyi, i had checked all the diodes they are not open or shorted. The fuse is good as well as the coils. All electrolytic caps tested off circuit within 5% range capacitance and esr good.
My suspect is on the 12 pin chip at U901 which is marked LNK6766V. I will attach the datasheet later.
Attached now the image of the board top and bottom view.
