    LeEco L554UCNN no display

    Looking for someone that possibly has worked on one of these Intertek sets. L554UCNN super 4 X55 LED tv. set turns on - -no display. backlights seem to light up but not fully. Also set will not turn off after turning it on with remote. measured CN8601 and CN8602 led connectors.
    CN8601 has 82 V and CN8602 has 27.4 volts. thats between pins 2 - 8 on the connector. Its very hard to get to the pins as its double sided. using a flashlight - nothing on screen. feels like LEDs are bad ? is there a schematic available to see LED pinout ?

    update - after examining the led conns (CN8601 and 2) - only four pins are on the ribbon cable even thou the connector has 8 pins

      you need to take look on the downside of both sockets and draw them so you will understand how many vled + and - the psu supply to each socket.
