    42pc3dv ysus question

    Hi everyone,
    I'm working on a 42pc3dv - no picture has sound. Bad fuse on ysus board( short to ground). I did the test on the ipm that I found online and it tested as bad. I have a few questions hopefully someone can help me out with.

    After removing the ipm, I tested at the rings on the board where the ipm sits, a lot of the rings have continuity to ground( I attached an image). Is this right?

    There's a resistor on the board R36, one of the leads has continuity to ground, does this sound right?

    The sideways cap has a slight mark on top of it ( its not bulged), does the mark indicate that its bad?

    Does anyone know where I could purchase the P8 connector?

    Thanks,
    Mark

    I can't answer definitively, but I suspect your resistor and IPM circuit board readings are fine. The cap doesn't appear to be blown. Someone here may have a junk board with the connector you need. I checked myself, and I couldn't find one.

    Edit: The P7 connector on the logic board should be the same as the P8 on the Y-Sus. The logic boards can be had for less than $10 on eBay if it comes to that. There are quite a few substitutes for your TV: http://www.shopjimmy.com/catalogsear...e]=Logic+Board

      Thanks for the reply capkid,
      The clip is completely off, not sure if I can just place the ribbon back in then sit the clip on it then hot glue it down, thinking that route if I cant get this connector.

        I've heard of people using hot glue on those broken connectors - never done it myself. I'm not sure if you broke the latch or someone else did, but I always use the index fingers on BOTH hands to carefully lift the latches; they're too fragile to pry up with one finger. I've broken a couple myself.

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Assuming...

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
          by Hakuu
          Hi There,

          This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

          After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

          More Details

          TV Model - LG OLED77G1PUA

          Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

          Sony xbr-65x900c main board issues?
          by jb_Bak
          Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

          Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
          Power Board Connector that goes to Main board
          CN6401
          Pin 01 NC
          Pin 02 NC
          Pin 03 "BL_ON": 0V
          Pin 04 "N/C"
          Pin 05 "STBY 3.3V": 3.5V
          Pin 06 "GND": N/C
          Pin 07 "AC_OFF"...
