    is this 125v with the leds connected?

    btw, you have some cracked solder joints, resolder all the ones with a faint ring around them.

        Re: Biglite led driver mbd001 Over Volatage

        I think you are getting 125Vdc because it has no load, the 80~90V rating is probably if it has working LED string connected to the output, LED power supply is the constant source power supply. Did you verify that the LEDs are OK?
        Any more details you have about this LED driver and the LEDs strings?
        You should also provide good clear straight shot pictures of the top and bottom side of the board.

            Is the LED panel made to be used with that power supply? What kind of panel is it?

                      Thanks for the follow-up.
                      "i notice fluctuate the voltage the meter 125v reading prove the 123V the 125V."
                      I am surprised that what you found on the output Voltage swing was only a couple of Volts, I expected a lot more if it has bad caps, may be your does not have fast response.

                          Hello, this is my first post and im just a beginner, so be easy on me guy. thanks



                          i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.



                          i have no datasheet at all for the LED lights, all i have is its length.



                          long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.



                          as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,...

                          Need Audio Driver for Thomson P14C4BK128 (Windows 10/11)

                          Hi everyone,

                          I'm looking for help finding the correct audio driver for my Thomson P14C4BK128 laptop.
                          The sound is not working properly, and I believe the audio driver is missing or not installed correctly.

                          Here are the details:
                          • Model: Thomson P14C4BK128
                          • Operating System: Windows 10 64-bit

                          If anyone has a working link to the driver or knows where I can download it, I'd really appreciate it.

                          Thanks in advance for your help!

                          Hello all am trying to reinstall my AMCAP Microscope on windows 10 but it is not working anymore. But the cam and the drivers are present in the Device Manager but there it saysWindows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) the drivers is : gl usb2.0 uvc camera device driver and i also get this mesage: Windows found driver software for your device but encou​ntered an error.
                          but it is quite strange because it did work on this same OS for one week ago and even for sometimes ago on that same but now nix.
                          any help?

                          by Daveleone
                          Hello TV experts! I have a UN55D6900. The successfully TV turns on, and the backlights light up, and I get a picture, but there is a section that is dim. I took it apart and 1 out of 4 segments of backlight LEDs are not lighting on both sides of the TV (in other words, the same segment is out on both LED strips).

                          I tested the LED strips with my LED tester and all of the LEDs light properly, so I believe the problem is with the PSU/LED driver board (BN44-00428B). The voltages at CNM810 (between PSU and main board) look ok to me. The voltages at CNL801A and CNL801B look off for one...
