    Re: Samsung ue32f4570ss with power supply BN44-00604F

    Hi, I've a Samsung UE32F4510 with backlit not working. Some times backlit power on.

    I've checked the led output on powersupply. All the pins are at zero value

    thanks

        Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
        by Tynan Dill
        I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

        Upon bringing it home and plugging it up, it showed a standby light.

        I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

        The screen seems to blackout and stay black, but with a flashlight I can see the display.

        With my Playstation 4 connected via HDMI, and running a game I can hear sound.

        Assuming...

        Samsung BN44-00262A H37F1-9SS power supply help finding blown value components!
        by cheeky2
        This Samsung combined power supply and inverter was replaced a while ago from a Samsung 37inch LE37B530P7W TV. However I would like to repair this one.
        I have replaced the Mosfets Q1820 and Q1821 ( FDPF7N50U) which were both blown and the fuse FM802S. The schematic for this power supply that is attached doesn't relate to this power supply as the driving transistors and diodes are D1830, D1831, D1832, D1833, Q1811 & Q1810 are nowhere on the schematic!
        Does anyone know what the components for D1830, D1831, D1832, D1833, Q1811 & Q1810 should be? I ask as I did change the Mosfets...

        Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
        by sam_sam_sam
        I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

        One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

        samsung ua55es6800 - no image
        by shlomim412
        hi
        having problem with samsung ua55es6800

        tv had backlight on, sound working - responds to the remote control but no image.

        check tcon board - had 12v in but no other voltages present.
        when disconnected left ribbon cable - got back voltages and half image with lines and distorsion

        when leaving only left side connected - again no voltages and no image.

        put a tape on all (cd?! lines) on the left ribbon cable and got complete but distorted image (horizontal lines).

        kept trying to block less pins on the left ribbon cable...
