Hi Mariushm do you still have the schematic for the power supply board of a Samsung T220 monitor? I saw you had posted it a couple of years ago but of course the link is bad by now. The old link was http://savedonthe.net/a/samsung_t200...tw20_22_sm.rar. I am really struggling with a power supply. My voltages are bouncing real bad between 1 and 1.9 volts when they should be 3.3 and 5 volts. I have changed the rectifier and all the caps, but the problem still persists. My rectifier DC output is bouncing between 165-170 VDC and the input is a fairly solid 122VAC.
