    HITACHI 58HK6100UA

    When changing channels the top quarter of the screen is dark for 3 seconds before lighting up as normal.
    This happens every time I change channels and is consistent. After the top backlights come on the picture is good.
    I think there are only 4 sets of backlights in this tv, do you think it’s the top row failing or a panel issue or panel driver
    problem? Or am I totally wrong?
    Many thanks for any help.

      The fault is 80% the top led bar, the rest is the bar connector, and the led driver if each bar has its own driver (bad diode contact, bad final electrolytic)

              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,...

              LCD Backlights Driver - Unknown Component
              by Spongebob89
              Hi,
              I have an "LCD Backlights Driver" and it is not working. After measurments and checking the routes of the PCB I beleive that this component on the red circle is a choke for filtering the supply voltage and block noise from the inverter to go back to the main board. When I measured in ohm and in diode mode with multemeter shows always OL. I shortcircuit this component and it worked. The current that I measured with multemeter is 550mA, so I want rated current 1,5x550mA=825mA~1Α. Am I right that this is a choke and if yes what value do you beleive is (maybe 15uH or the...

              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 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!

              Hitachi 50hyt62u-k tcon or driver boards ?
              by Chrissygizmo
              Hi everyone.

              This is my latest problem, I have a Hitachi 50HYT62U-K tv. I was informed off the previous owner that it had been squirted with water.

              I originally thought it was going to be a right off and I would be stripping it, but I've messaged around with it and I've had a good picture on it earlier.

              I have got the problem down to either the tcon board, ribbon cable or driver/buffer board (Not sure what they are called) . I have messed around with it with hammer hands & I've managed to snap 3 of the clips that keep the ribbon cables in place...
