    I'm guessing it's these 2 dull ones? https://i.ibb.co/MZBf9WZ/fuse.png

        OK, so done a test
        D10/D11 = 550
        D8/D9 = 895
        D13/D14 = 375 using a EEDM501B multi meter on the 2K ACV setting

          Check some youtube videos on diode testing.

            Can you explain how you test the Diode on the 2K ACV setting?
            What setting of the meter did you use to test D8/9/10/11?
            Are you testing the diode with TV still plugged into the AC outlet?

              I'm testing the diodes with a diode setting on a different meter they came back with a reading

                So, I went ahead an purchased a new main board, turns out it's something further cause it's doing the same thing with a new board in the TV

                  I have a Haier 50" LE50d3505b television that is "dead." No image, no standby lights, no sound, no nothing. The power supply board is HKL-500201A.
                  I have tested diodes 10/11 using the "diode setting" on my multi-meter. I got .000 readings for both. For diodes 13/14, I got .177 for both readings.
                  Do you think diodes 10/11 are the issue and to replace them? If so....would these be the correct diodes to replace them with: https://www.ebay.com/itm/11376729897...QAAOSwDw9bLDvU

                  Thanks!

                      Can confirm, D10 or D11. Had to take them both out of circuit to test though.
