This LED TV died suddenly while it was on. Now it does nothing.
Typical when I spot two or more DO-201 schottky barrier diodes in parallel: one of them is shorted. In this case, one SB5150 from Taiwan Semiconductor (positions DM807C and DM809C). This is 5A 150V. There’re two, so we need 10A 150V to match original components.
I replace both with a single LiteON MBR10150CT (dual schottky barrier). Both anodes go to original anode holes. Cathode goes to one of the original cathodes holes, with a wire. TO-220 IC is bend over the PCB and I put a scrapped small aluminium heatsink, flat enough to fit the TV box. Make sure it doesn’t get too close to any other component.
