    Been searching for months to figure out where I stand with a UN556150 . . .

    I have a UN55SE6150FXZA that doesn't have a picture and no sound, but reacts to the remote. I get the 5 start up blinks, but when I pull the power I get a 5-5-4 in double blink sequences. I can't find anywhere any listings for Blink Codes. I know that this model is most susceptible to the cap issue. But would really like to get this thing fixed. So I can take my time in rebuilding my DLP.

    Any assistance will be greatly appreciated.

    Thank you . . .

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

      'UN55SE6150FXZA' You need to verify the mode.

      UN55ES6150FXZA?
      There are more than one version of the boards so we need good clear pictures.

        We have seen this model come into the shop many times with bad LED's and never seen bad caps on it. Disconnect the main board from the power supply and see if the back-light turn on. If not then we know for sure its going to be power supply and or LED strips.
        Once the power supply has had time to discharge, connect the main back in and perform the flashlight test. If you can faintly see the picture in a dark room by using a flashlight at a 45 degree angle about 2 or 3 inches from the screen, then you know your issue is backlight.

          I think if the Backlights have a fault the set may shutdown. So if disconnecting the Main Bd from the Pwr Bd gives backlight, then Main Bd faulty. However, if the result does not give backlight the Pwr Bd or Backlight is the fault....In most of my encounters the Backlight LEDS were bad.

            Samsung UN65NU6900FXZA Stand-by light on but voltages on PS indicate TV should be on
            by DXseekerMO
            Hello everyone!

            Tonight I picked up a Samsung UN65NU6900FXZA with a curious issue.

            Symptoms:

            2) TV does not appear to turn on
            3) Backlights do not illuminate, voltages associated with backlights on Power Supply are not present
            4) "Power on" terminal on Power Supply has 3.26v
            5) "A13V" terminals have 12.9v
            6) Stand-by test jumper on Power Supply has 12.9V
            7) Optical audio jack on Main Board illuminates

            Schenker VIA 15 PRO, PF 4NU1F V1.0, P/N: MBPPF4NU18-F310 - 36mA in stand-by
            by FriedFred
            Hello, everyone!
            I have here a Schenker VIA 15 PRO, with this numbers on the board: PF 4NU1F V1.0 and P/N: MBPPF4NU18-F310 .
            I took out the memory and the battery and the SSD.

            So, in stand-by, only the board, takes 36mA. No power-button pressed at all, I can measure 1.8V, 3.3V, 5V. All coils present voltages except the two power rails for the CPU. The CPU is a AMD Ryzen 5 4600H.
            After pressing the power-button, the current raises to 500mA and the two power rails for the CPU show up with 0.8V.
            After several seconds, the fans switch-off and the board keeps powered...

            LG OLE65C1 Stand-By issue
            by Titus6
            Hello everyone,

            I bought an OLED65C1 refurbished TV back in 2022 from a shop. The TV is awesome, this is my first OLED and I really love it.

            However I have an issue with the TV since the end of last year. I noticed when my TV is in Stand-By, sometimes the LED goes off then comes back on. When do so it seem periodical. It only goes away for 1-2 seconds, than comes back on. The TV NEVER turnes off, while it's on, so it's not overheating issue or electrical power issue.

            I bought a service remote (MKJ39170828) and checked the menu 3. Power On/Off Status. I took...

            the laptop is starting ONLY if a usb drive (or a mouse) is connected on the Type-c port.. leaving it empty hangs startup on DynaBook BIOS LOGO (never seen something like this)

            Vizio E400i-B2 missing stand-by voltage
            by DXseekerMO
            I picked up this Vizio E400i-B2 with no stand-by light and diagnosed it with missing stand-by voltage. I found a Power Supply at ShopJimmy, installed it but it didn't work properly. SJ refunded the transaction and did not ask me to send the board back.

            So I took some voltage readings upon the original board. Here's what I found:

            Main caps have 169.9v

            AC detect voltage is 1.3v

            None of the MOSFETS appear to be short.

            The opto (IC106) that appears to have something to do with stand-by voltage has 3.0 volts on terminal 1...
