    Toshiba 55G310U. Power supply?

    This TV has no picture and is dead, I have the rear cover off.
    With both inverters connected, the mainboard puts out all the nessessary voltages. If I attempt to power it up with inverters connected, The L.E.D stays lit but the 12 Volt and the 24 Volt disappear.

    Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

      I am not sure what you are trying to say. Perhaps I don't understand...

        "the mainboard puts out all the nessessary voltages." Are you saying that the PS-ON, BL-ON, and DIM signals are all present?

          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...

          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...

          Toshiba 37bv701b power supply main rails
          by semiRocket
          The set is not turning on, when buttons on the front are pressed the button press sound is coming from the speakers, but the set is not trying to turn on, consuming only couple of watts.

          I am troubleshooting a Vestel 17PW26-5 from the set. Not sure how it is supposed to turn on main supply, but with the main board disconnected not getting the main supply to turn on either.

          Standby supply is working, PFC is working (390V), but the main supply is dead. Checked the mosfets and driving transistors and found they are not shorted and showing a diode junction. The suspicious...
