I have a Samsung S32D850T monitor with some issues - the power light LED will flash and the monitor will not turn on. The problem is definitely in the power supply board (confirmed with swapping in a known good board). Unfortunately, a replacement is not readily accessible. Below are links about the monitor and board information.
