        Those are far from hi resolution and those aren't your boards. If you can't see it on your screen, I can't see either on mine. We need to be able to see and read details.

            Looks like your main board is sending PSon, but the PSU isn't turning on.

                Here is a service manual for it.

                Disconnect everything from the PSU and force it on by jumping STBY voltage to PSon with a 1k resistor. Plug it in and check all the output rails.

                  Be careful in the primary section on the power supply. When the PSU is working correctly you got around 400V DC on the main filter cap.

                    Insignia NS-LCD19-09 no standby LED; (new problem)
                    by valvashon
                    Having a new problem with the 19" Insignia that I modified with one of my automatic turn on circuits. That is now completely disconnected so that is not the issue. I was doing some modifications on that circuitry and managed to short something out on the underside of the power board.
                    Actually found and bought the service manual (who knew it was even available?!) which brought me to the High Voltage Startup Circuit controller chip.
                    Looking up that chip number- LD7575APS brought me to the attached datasheet. I have marked my voltage readings on the schematic sheet (open in new...

                    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...
