La-d401p Schematic

The LA-D401P is a switch-mode power supply (SMPS) board designed by LG. Its primary function is to convert AC mains voltage into the various DC voltages required by the TV's mainboard and the OLED panel itself.

Because OLED panels require specific current regulation to fire the organic pixels, the precision of this board is critical. A failure here doesn't just mean "no power"—it can also manifest as backlight issues (in older LED/LCD hybrids) or, in the case of OLEDs, a failure to initialize the panel. la-d401p schematic
