Question about Samsung SyncMaster 740N 17" LCD Monitor
Can you give me, how to repair, the LCD samsung 740n, Screen Display Darkness...
Theres only one solution to the problem you have to replace the whole power supply board .its easier to replace them than finding and soldiering the defective parts like the capacitor on the board .u can just replace the power supply board if u think the power has a problem. if it doesnt work then u have to replace also the main board or the board connecting the rgb cable.its more expensive to replace the board but its worth it. ur lcd will work better and its easy to put them on the lcd casing .
