    That's what I was leaning towards. Well I will get one ordered and let you know it does. Thanks for your help. Got to learn somehow lol

        A common problem I saw on this power supply was bad solder joints on connector CN202. Use a desolder pump to remove all the old solder on all the pins, clean them up with isopropyl alcohol and apply fresh solder to all the pins. Before you re-install loosen the screws on the led driver board and pull that board up to meet up with the pins correctly before you slide it in place keeping two fingers pinching the two connectors together so it takes the stress off your fresh solder joints. Then tighten all the screws down.

            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 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.

            Samsung UN55KU6300F no standby voltage

            I have no standby indicator light and no light on the optical port. I checked the standby voltage on the two mosfets in the top left and they both read 30mV. I checked the fuse and it has continuity. I also checked the voltage on the two large 450v caps they both read 153v. All of these voltages are the same with and without the main board connected as well as with backlights connected/disconnected.

            Nothing looks obvious like a burned ceramic disc cap or bulged electrolytic. No burned resistors, diodes, or anything like that....

            Philips TV 37pfl5604h/12 no standby voltage
            by Bad_IC


            Hello,
            I have a problem with this TV, the standby voltage is not present. I have checked the components around the IC fsq510's area and they seem to work, also replaced this IC but the problem persists.
            These are the voltages in some pins of IC fsq510:
            Vcc=18v
            D=320v
            Vstr=154v
            Unfortunately, I couldn't find the schematic
            What else could I check?
            Is it possible to provide standby voltage from an external source to allow the TV to turn on?
            Thank you​...

            Asus GL503GE 3.3 standby voltage low
            by brock-s
            An Asus GL503GE laptop arrived that had had a screw dropped on the motherboard while the battery was connected. This resulted in a physical damage to the 3.3v / 5v voltage controller RT6575DGQW (pu28 on schematic, page 40). Additionally, the trace to pin 12 (VIN 19v supply) was burnt.

            Replaced the RT6575DGQW with a new one, repaired the damaged trace. Only getting 0.7V instead of the expected 3.3v standby voltage (3V_S5 on schematic).

            Replaced the AON7408 PQ60 mosfet from a donor board as resistance was low on the gate (I did not write this value down, as I optimistically...
