    55G310U Toshiba Dead

    Can't get anything out of it. Power supply outputs all ) as well. The obvious answer is Power Supply Board unless it needs to be switched on by the Main Board. Suggestions?

    Thanksl

    Power supply typically supplies standby voltage to the main board. When the TV is turned on, processor will send a power supply on to fully turn on ps and backlight on signal. If you have no standby voltage, power supply is suspect. Should be a main AC fuse you can check but fuses will blow due to shorted components.

      PS fuse checked OK, and with no standby voltage, I was assuming a PS problem. Thanks for the confirmation.

        What is your voltage across main capacitor?
        I assume no responsibility for any stupid suggestions I might post.

          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...

          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
          by Asraf Atb
          Hi everyone,

          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

          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...
