TV has black screen -only sound. Can't see any faint image with led backlights disconnected on psu or backlights when main board is disconnected from psu. Tried replacing psu (Vestel), main board (Vestel)and t conn (LG)boards with supposedly working boards from Ebay.
Can anyone confirm what the voltages should be on any of the boards? Can't find a service manual anywhere and there are no voltages printed on boards.
