Samsung LNT4671F Board ? Can't Post
The power supply board ### is bn4400166C I need to know what the diode ###'s are for position DB851 and DB803 one is reading shorted and the other is reading down at a .12 while still on the board. Any help is appreciated!

DB803 has the coil of a relay across it - unsolder and lift either end from board. It will now check fine.

For some reason the board schematic only shows page one - No pg 2 or 3.
Lift either end of DB851 from board and do the reading again.
