If you can share a clear photo of the top and bottom of the board (and any IC markings you can read), I can help identify the power architecture and likely failure points — no need to share the actual proprietary drawing.
It looks like you're referencing a specific piece of hardware: BDL51 LAD711P REV 30 — likely a power supply or main board from an LCD TV (possibly a Samsung or LG chassis, given the naming pattern). bdl51 lad711p rev 30 schematic work
However, I cannot directly provide a downloadable schematic file or a proprietary feature code for that board. But I can help you find the correct feature, identify what you likely need, and point you toward how to obtain the schematic. If you can share a clear photo of
