    LOGIK L22FED12 No Image/Sound - Possible DVD Drive Problem?

    Hi, have this LOGIK 22" TV which has no image or sound? I think it may have something to do with the integrated DVD player but not 100% sure?

    With the mains cable connected and switched on, there is no STB light or blue on light but the DVD drive is spinning? If I disconnect connector C1102 on the PSU (4 blue wires) this stops the DVD drive from spinning and the blue on light comes on? Sometimes I can get the TV in to red STB light so able to turn the TV on using either the on/off switch or remote. I have tried another main/PSU board but get the same results as with the original board.

    I'm wondering just what the board on top of the DVD player doe's?

    Thanks.

    unplug the dvd player, the tv works fine without one.

    then turn your attention to votages on any voltage regulators on the main board.


    to answer your question btw, the board on the dvd player IS the dvd player, it's a standalone player with 5v / 12v input and a/v output on the top connector.

      Have unplugged the DVD player from it's board and taken some readings from the white 10 pin plug both when TV in STB and when on. Not got to checking the voltages on any voltage regulators as yet.
