    Led driver TPV101AD Datasheet

    I have tried to find the datasheet for this IC. It is a led driver ic.

    on this power supply in my case. It is designed with two exactly the same IC driving one ledstripe each.

    TPV 715G8620-P01-000-002S for Philips 43PUS6412

    Located bottom right hand side.

    Anyone with better friendship with Google than me? ;-)

    Thanks in advance.

      There is only a wiring diagram.

          mmm...had that one. Just need to know the expected values etc on each pin.

          Thanx anyway.

              LED_VCC is likely 12vdc
              Dim could be between 0 & 3.3~5v depending on signal from main board
              EN depends on BL_ON/OFF status 0 to 3.3~5v signal from main board
              Iset is likely very low around 1 volt or less, depends on led current (leds on or off)
              LED is the return for the led string, likely 1~2 volts if led's are on
              COMP is a reference from the +LED and is likely no more than 2.5v

              What are your backlights doing? You likely have a bad led in one of the strings

                  Before they just flashed once and then turned of. I had a bulb in series with PSU and when I disconnected one of the backlight stripes (of two) the unit started. Then i could connect the other one and it still worked. But idf both connected then reboot. over current protection some how. BUT...when doing the procedure above and both were lit, the bulb gloved 20%. Some partial shortage....

                  I have fixed the problem...even if i exchanged both of these ic:s (yea...there were two identical circuits and both ic:S that had same outputs) ..one of them did not work somehow. Exchanged one of them again and now it works. The backlight turns on without any problem. But i had no datasheet for those IC:s but narrowed everything down to one of the ic:s anyway.

                  the voltage that you mention are there now after testing. Soo nice input here man. Thanks.

                      Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
                      by howardc64
                      Problem

                      Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



                      Model & Board Pics



                      Conflicting Spec

                      Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

                      Audio Driver/ Controller IC labeled GAD SHM? Datasheet
                      by Iceking007
                      Hello,

                      Could anyone provide me with some information on an IC labeled GAD SHM?

                      This is some sort of audio driver, it connects directly to left and right speakers via some inline resistors (small value of course).

                      I've attached an image of the chip on board, I counted 20 pins. It might be some sort of op amp; it isn't the primary audio processor, as there is a separate dedicated chip for that.

                      Thank you for your time....

                      Audio Driver for Thomson P14C4BK128
                      by charif
                      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!

                      how to install gl usb2.0 uvc camera device driver on windows 10
                      by bohaboha
                      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?

                      LED DRIVER KEEPS DYING
                      by osrex
                      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,...
