    Philips TV 37pfl5604h/12 no standby voltage

    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​

          Hi William1967,

          thanks for your reply.

          I have done some readings, please see the attached pic

          I think the primarie power supply is working.

              Is this diode on the secondary short-circuited?

                  I think not, because I read with the digital multimeter between anode/catode 0.217v

                      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....

                      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....

                      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...

                      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...

                      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...
