    Whoops-Shorted out SMPS by accidental probe slip

    So, Title says it all.

    I got a free TV today, Element ELCFW328. Worked fine for about 10 minutes and would shut down to completely back to standby and would then, turn back on with no issues until about 10 minutes later.

    Went to checking some voltages on the connectors and I believe my probe touched the standby and 12v.

    No, no standby voltages but the other voltages seem okay.

    Tested Diodes and D16 on the cold side is really the only one that wasn't right in circuit so took it out and it's reading 0.201v in Diode Mode.

    This is the board

      I viewed the pic but could not see where the damage was. List the make and model of set and part # of the power supply and a close up of the damaged parts

          Hi I know this post is old, but I am trying to fix the exact same PS, and comparing your board to mine, the part labeled "T1F" on your board looks completely melted. Don't know if that helps or if you even care anymore, but thought I'd give my 2 cents worth.
          resistance is futile

              Accidental slip of the hand caused a spark on Capacitor. Is my PANEL killed in action?
              by Axis937
              Hi folks, newbie here. My intention on a working monitor was to test for voltages on the various pins. Somewhere near the ribbon to the monitor, there we 2 caps. One was reading around 5V and the other was maybe about 12 or 14V . Cant really recall. Then it happened. The multimeter kissed the 5v cap and the other cap. Spark appeared. NOW... the part where the spark happened ( Caps near the Last ribbon cable ) is now totally white. 1/6 part of the screen is white. From my little understanding , i came to learn that there are transistors inside the TFT panel. Could that be a issue then? I have removed...

              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.

              Onkyo DX-V500 Laser Disc Player - weird SMPS fault
              by dkneyle
              This relic from a technology path that came to a dead end (but still has historical interest) was brought in with a dead SMPS, which is based around a MK1210 device. I got it going after a battle. It seems to have a strange design - if it's not getting feedback that the secondary is OK it cause the big FET to go into full conduction and overloads resulting in a blown fuse at best or something worse! I'm using a Dim Bulb Tester (70W/230V) which thankfully has saved the day a number of times whilst repairing.

              Now, it loads a CD OK. The motor voltage output (which is built onto the SMPS...

              Samsung UN40H5003 boot loop every ~8 seconds
              by eigma
              Hi, I rescued a Samsung UN40H5003AF (H = 2014 FHD) from the curb. Symptoms are: standby (red) light comes on, stays on for 8 seconds, flickers off, then comes back on, and the cycle continues.

              Service manual: https://www.electronica-pt.com/esque...is-u8la-71272/

              SMPS board: checked voltages, all seem normal (A13V = 12.8V, UD = 3.3V, PWM_BLU = 0.77V, PS_OnOff = 5.5V). Remove 10p cable to main board -> backlight comes on. I think this means SMPS board and backlight are good.
