    LEDs shouldn't flicker, so more than one LEDs are bad.
    And you've probably forgotten a film or put them in the wrong order if you can see the LEDs.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        It looks like two LEDs are shorted out (not on).
