    Hello all.

    I have a problem with the Samsung LE40A536T1F TV.
    The TV has stopped displaying a picture.
    The TV has power (after turning on, you can hear the loudspeaker of the received channel, no matrix backlight, the remote control responds).
    Please help.

    Added after 3 [minutes]:

    The fuses checked with a multimeter are ok.
    The capacitors on the power board are not swollen (checked after desoldering with the UT601 multimeter http://www.uni-t.eu/pl/3507-miernik-uniwersalny-ut-601
    Checked capacitors marked in red

    With such knowledge of how the TV works, even MacGyver will not help. ;)

    Very nice and friendly forum.

    You can't do anything with sarcasm here. You do not write anything about the voltages on the inverter, is there a signal from the processor to the inverter, or you have SM. You have entered "electronics" in the specialization of your profile - what for?
