    Sceptre E55 no power no led light. Help!!!

    Ok so I have a 55 inch Sceptre E55 that the person said they were watch then it just shut off and never came back on. What should I check and how to go about it. I have a multimeter so I can follow any direction you give. Thx

    Look at the power supply board connectors to see if there are pin labels printed on the top or the bottom side of the board or not.

        I hope OP at least did the fuse check without giving instruction.

                The fuse (red square) will check like a short with meter in ohms test (same as meter leads shoted together)
                If the fuse is ok, connect it back into the tv and check if you have 5VSB. 5 volts dc standby voltage

                  So I just check it from underneath the board right? If so when I test it nothing happens my meter just stays on OL

                    Test in diode mode, if you have a meter that beeps when you touch the probes together, if fuse beeps it should be ok, probe on each end of fuse, make sure you have the proper two points on bottom of board.

                      A common failure seems to be D10 & D11, check them in diode mode to see if they are shorted or not.
