    Fuses look also good so I need a bit of help please
    Voltages
    Con5
    Gnd
    Gnd
    +5v =5.0v
    +5v =5.0v
    Ps/on =4.1v
    +5vsb = 5.0v
    +5v =5.0v
    +5v =5.0v
    Gnd
    Gnd
    Gnd
    +12v =13.3v
    +12v =13.3v

    Con3
    +12v =13.3v
    +12v =13.3v
    On/off =0.00v
    Adj=5.0v

    Led backlight voltage

    +76.1v -0.00
    +76.1v -0.00

    Main cap is 323v

    Thanks

    No standby or no backlights?
    I assume no responsibility for any stupid suggestions I might post.

        If I jump ps/on and 5v I get voltages
        +12v go to 11.8v
        Ps/on goes to 4.8v

          So mainboard not sending signal to turn on.

              Have you checked mainboard voltages? Try heating up your processor to see if TV will turn on?

                Zombie Samsung UN55NU6900F dead / no standby voltage - randomly came to life after hours of troubleshooting then died
                by tvguy12012012120
                This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                Vizio D50u-D1 Dead Set No Standby
                by fharris1977
                Hi. I got a Vizio with no power or standby, and won't turn on with remote or button. I checked the voltages on the connector and all read 0.00V or nearly 0(0.050 ON/OFF pin). None of the pins are labeled STB for standby although I do see some 5V pins. Other than the obvious standby led, which isn't coming on, is there a way to check for standby voltage on this PS. I'm trying to see if my problem is the PS or mainboard. Some Vizios I have fixed with no standby led me to think it was the PS but it turned out being the mainboard. Any experience with this set would be greatly appreciated.

                Samsung BN44-00259A standby question
                by Crystaleyes
                Hi all.

                I started a thread while back regarding TV power supply standby circuitry as it is something I am not quite on top of.
                SMPS theory and function is becoming more familiar, however the standby part is still a bit of a mystery.

                Anyway, a friend has this TV with the above mentioned power supply board which has no standby voltage, nor any other voltages leaving the board.
                The mains AC comes in fine, gets filtered and rectified with power is on the main filter cap as well as the transformer and drain pins of the ICE3B0665J, but that's it.

                JSK4228-050 Power Supply Standby voltage changing! (Possible from Wharfedale LTF37K1)
                by reessi
                Hello,

                I am trying to re-purpose this power supply that I saved years ago from a tv with a cracked screen for a monitor but that is not really that relevent at the moment. I do not recall which tv but a google search looks like it is from Wharfedale LTF37K1.

                You may notice I made some alterations moving some components to the top and some wires which are from a 5v regulator I fitted to the 12v output as the monitor requires 5v. The standby was already at fault from the beginning, it has nothing to do with the alterations...

                Years ago it had some bulging caps...

                Yamaha TSX 120 Standby Problem
                by psssst
                Hello forum. I've recently been given a Yamaha TSX 120 DAB radio and ipod dock. Its working well however when put on standby its using 6.3 watts. The manual states less than 1 watt on standby. I measured this with a plug in monitor which seems accurate with other items. In use it uses around 7.5 watts. Firstly has anyone who owns a similar radio also got a plug in monitor to check if this is normal with this unit? In the first half a second the monitor shows 0.3 watts which I suspect is what it should use but something is switching it to be almost fully powered. I've searched the manual for eco...
