    PWM Dimming Control Signal low voltage drop LA-E841P

    JEDP pinout LA-E841P:
    4,5 MLO (Main-Lane)
    7,8 AUX (Auxiliary Channel)
    9,10 VCCS (Power Supply +3.3V)
    11 HPD (Hot Plug Detect)
    15 LED_EN (BL_ENABLE Signal of LED Converter)
    16 LED_PWM (PWM Dimming Control Signal)
    19,20 LCD_VCCS (BL Power)

    Have an issue with pin 16 (PWM Dimming Control Signal): low voltage drop!
    Any help would be much appreciated!

      LED_PWM(INVPWM) comes directly from SOC. Attach schematic if you have one for better understanding. There can be way out but you will loose brigtness adjustment control.

          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

          Requesting Help For GA-970A-DS3 rev. 1.0, No Post code, no RSMRST# signal
          by AstutePauciloquent
          Hi everyone, over the past few months i have taken a deep dive into motherboard diagnostics and I love the challenge. Currently im trying to learn all about the signals that travel around the motherboard, such as frequencies, enable signals High and Low logic states etc. And i have been learning to read and using the Schematics for this board that i requested here on Badcaps forum, from a few months ago, this is such a great place for these.

          I’ve been working on a GA-970A-DS3 (rev. 1.0) that does not post. This motherboard has been my main learning board. I would like share...

          BL0202C BL0202B BL0200C Datasheet
          by Document Archive
          The BL0202C BL0202B BL0200C are 2ch output LED driver IC for LED backlight, and it can do dimming to 0.02% by external PWM signal.

          This IC realizes a high efficiency by the boost convertor control that absorbs variability on VF.

          The product easily achieves high cost-performance LED drive system with few external components and enhanced protection functions.

          Features and Benefit

          Boost Convertor

          ● Current-Mode type PWM Control
          ● PWM frequency is 100 kHz or 200 kHz
          ● Maximum On Duty is 90%

          Vizio M65Q7-H1 Red Vertical Strips fixed by tape blocking LC1 signal to half of the panel
          by howardc64
          Failure Symptom



          No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.

          Where is the short?

          Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.



          Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but...

          PS4 fat has inconsistent signal after HDMI replacement
          by supravit2000
          Hi, guys!

          I am not a professional, all I can do is solder stuff on the boards, so I would really appreciate it if someone with knowledge shares his experience/thoughts on a problem I have with a PS4 console.

          My friend gave me an original fat PS4, board model SAB-001, with WLOD, that has been previously opened. I changed the HDMI port, couple of pads on the board were ripped, which I connected to the corresponding caps/resistors? Just did so as in a shown diagram (one of the ground pads I ripped off and left it not connected). However, there was still no signal, so...
