This Emerson LCD TV came in my shop dead. After testing a few components I found a bad diode on the secondary side of the switch mode transformer. Location number was D631. Someone suggested an NTE 579 might make a good replacement but Digikey had a 5 amp schottky diode which handled more current so I figured was a better option. their part number is SB5100DICT-ND
I also replaced C633 which was 220 MF at 16 volt and
Just to play it safe I replaced C631 even though it checked Okay. It might not have been necessary but because this capacitor appeared to be the filter for this diode which shorted I didn’t want to take a chances.
It’s value was 2200 MF at 25 volts.
