Schematic PDF for the Samsung UA40EH6030 LED television, with the U71I designation appearing in the name, 8.66 MB. The document helps with tracing power supply rails, LED backlight drivers, main board voltages and panel interface signals when a set shows no picture, no power or clicking. It opens in any PDF viewer. Samsung uses different main boards across regions and production runs, so compare the board code printed on the PCB with the diagram before replacing parts.
