I have a D55u-d1 with no display. Its turning on but not properly. The standby light flashes when the power button is pressed, after a while it goes back to standby. I checked the output on the power supply. Every 12v pin reads 19v and every 24v reads 22v. I've seen other posts here about this exact issue but they replaced their power boards and had no luck and the forums were locked. Trying to get some answers. I get 19v even when everything else is unplugged. Definitely a power board issue but if there is something else causing the power board failure then id rather not toss $50 in the trash. Thanks.
