Hi,
Pulled this monitor from storage and tried switched on power but i only got white display.
Not sure whether this monitor worked in the past.
I searched for schematic or service manual for the monitor and board model 715G4924-M01-000-0H4F but there is no info whatsoever.
Checked the fuse F701 for continuity and tested ok no short. Next i do dc voltage test on 3 pin regulator N32B 960T43 (upper middle part of board) at u702, got 5v at pin 3. Another 3 pin regulator N32C 912T43 at u703 also showed 5v at pin 3.
I also did dc voltage test at lvds connector at pin 1 of CN803 and got less than 1vdc. Something not right here. Probed the diode at D801 next to the lvds connector and got 57vdc. Can someone kind enough to help and point me where to check for further test so this monitor can be used again. Thanking in advance.

The fuse should have continuity ie a short. If there was no short (open circuit) there wouldn’t be continuity.
Just had to say it.
